RT0-cycle time
The parameter for the cycle time for the RT0 time slice (for position and speed controllers
and motor control) can be set here.
The value must be between 62.5 µs and 1 ms; the standard value is 250 µs.
The RT0-cycle time can be changed only when the drive is inhibited.
The RT0-cycle time must not fall below the preset current controller cycle time 
Z47.65–. This is monitored and as the case may be the error 501 will be triggered which
inhibits enabling of the drive.
1.10
Task fieldbus cycle time
The parameter displays the cycle time for the task fieldbus.
The task fieldbus cycle time must not fall below the RT0-Cycle time. In this case the task
fieldbus cycle time is limited to the RT0-Cycle time, the error 505 will be triggered and thus
the enabling of the drive will be inhibited.

Configuration
3.4.1
Power unit
All the power unit related data are divided into two groups. The first group includes the
so-named power unit data which is shown in parameter group 129 and cannot be written
to.
The power unit has a non-volatile memory which holds the power unit data. When the
controller is initialized, these data are read out and transferred to the corresponding parameters in group 129.
The second group, parameter group 130, contains all the other power unit working data.
These parameters represent either constantly changing physical quantities or certain settings which generally can be altered.
Detection of a mains failure
The detection of mains failure at external supply is possibly not fast enough for specific
applications. Therefore a mains failure detection is optionally possible via the DC link voltage (see Z130.35–).
Behavior at mains failure
The drive can be configured that operation is possible at a mains failure for a set time
(Z130.25–). Different kinds of behavior can be set (see Z130.10–):
– Disable only motor operation (generator operation is enabled, field current is further
supplied). This behavior is only possible at external supply.
– Normal operation (motor and generator operation): Normally this option makes only
sense at a DC link combination if another axis feeds back power to the DC link. This
behavior is only possible at external supply.
– Disabling and automatic restart: The pulses are inhibited in case of detected mains
failure. The drive changes to "Switch-on inhibit (1)" state and coasts down. If the time
of the mains failure is shorter than the set Mains failure delay (Z130.25–), the drive
restarts automatically. The drive changes automatically in the "Operation enabled"
state again.

Configuration
At mains failure a motorized operation is advisable, if there is enough energy in the DC
link or if several axes are coupled via the DC link and simultaneously at the other axis
energy is supplied to the DC link.
NOTICE!
It must be ensured that the mains is not activated during motorized operation (for example by switching off the main contactor), if motorized operation is activated at
mains failure. Otherwise the charging circuit of the DC link can be damaged!
The setting for the behavior at mains failure effects only in the set time in Z130.25–. If the
time is set to 0, the drive is inhibited at once at mains failure and an accordant error message is generated (error 1016 Mains failure or error 1032 Supply not operational).
Bit 2:
If Bit 2 of parameter Z130.10– Mode is set, the controller activates a time monitor
when a phase failure is detected. The drive reports warning/error 1047 „Phase failure“.
The motor current is restricted to nominal current.
The further behavior is determined by the response which is set in warning/error 1047.
m Response is „No response“
The drive remains enabled.
After the phase error delay time has elapsed, if the phase failure condition still exists
the drive generates Error 1015 "Phase error timeout" and inhibits the pulses to the
power unit. 
If the phase error is cleared during phase error delay time, the controller deletes the
warning and switches back to the non-reduced current operation.
m Active braking („Return motion“, „Stop (Ramp-down time)“, „Stop (Quick stop time)“,
„Stop at current limit“, „Controlled stop“, „SS1 stop“)
The drive effects an active error response, changes to „failure“ state upon completion and inhibits the pulses to the power unit.
If the error response will be not finished up to the phase error delay time has
elapsed, the drive generates Error 1015 "Phase error timeout" and inhibits the pulses to the power unit.
Also if the phase error is cleared during phase error delay time, the pulses to the
power unit will be inhibited finally.
m Pulse block
This response is not permitted. In order that the pulses are inhibited fast as possible,
the parameter Z130.24– is set to 0.
If Bit 2 of parameter Z130.10– Mode is not set, the phase error delay time doesn’t act.

PWM frequency
The PWM Frequency of the drive controller and the cycle time of the current controller are
set in this parameter.
Valid values: 
PWM Frequency
Current controller cycle time
2 kHz
250 µs
4 kHz
125 µs
8 kHz
62,5 µs
16 kHz
62,5 µs
NOTE!
If it is intended to operate a PWM frequency of 2 kHz at an axis unit, it first must be
checked if the operation of the drive is permitted (e.g. if the related values of the motor, or of the motor filter if one is at use, still are valid for this PWM frequency). At a
switching frequency of 2 kHz the current controller cycle time is 250 µs - so the adjusting range of the output frequency is 0 to 225 Hz (see the electrical data in the instruction handbook of the device).
Generally:
m The band width of the current controller is inversely proportional to the current controller cycle time.
m The noise of the motor caused by the voltage signals in pulse form, drops with an increasing PWM frequency.
m The thermal loading in the IGBT model decreases along with falling PWM frequency.
Therefore the attainable peak current length increases with falling PWM frequency at
constant peak current while the nominal current of the device increases during continuous operation.
m The adjusting range of the output frequency increases if the current controller cycle
time sinks. This adjusting range refers to the stationary operation and to the linear
range of the PWM - that means without an overmodulation and provides frequencies
that generate excellent output voltages.
n The quality of the generated output voltages is given by how close they are to the
effects of ideal sine voltages and depends on the ratio current controller frequency
fI-R (fI-R = 1/current controller cycle time) to the maximum output frequency fmax:
fmax = fI-R / Kpf. The greater the proportional factor Kpf the better the quality is which

Configuration
is reached. A multiple of 6 is preferred for Kpf because of the 60° symmetry of the
three-phase system or of the voltage in the voltage space vector. Typically the
Kpf = 18 is selected to provide a good quality.
n The adjusting range is determined as follows (see chapter "Electrical data" in the instruction handbook of the device.
Current controller cycle time Output frequency adjusting range
250 µs
0 - 225 Hz
125 µs
0 - 450 Hz
62,5 µs
0 - 599 Hz (900 Hz) *)
*) 900 Hz are technically (from the control point if view) possible
n The controller specifies an upper limit for the output frequency of 599 Hz so that the
900 Hz, which are technically possible, may not be reached (for details over this limit
refer to the relevant Baumüller sales department. Key word: Export limitation).
n The converter can generate output voltages with frequencies between fmax and
599 Hz and the controller permits them. The quality of these voltages can't be guaranteed.
Change of the PWM frequency during operation
Up to Firmware version V01.08 the parameter can be changed only when the drive is inhibited. From firmware version V01.09 the parameter >130.15< can be changed during
continuous operation by the user. However, there are a few limitations:
m For applications with high demands on the performance (e.g. synchronous operation)
the complexity of the controller setting with variable current controller band width would
be too high. For this reason the PWM switching in enabled operation is restricted to the
speed control and current control operating modes (see Z109.2–).
m The current controller cycle time may not exceed the RT0 cycle time Z1.8–. The value
will not be accepted if this condition is violated by writing a PWM frequency during the
continuous operation.
m The power unit peak current Z6.25–, depending on the PWM frequency, limits the
maximum drive current Z19.6–. If a higher PWM frequency is entered at continuous
operation, it could happen that Z19.6– should be reduced. In this case the change of
the PWM frequency is rejected. However, the change is allowed in the inhibited state
and Z19.6– is limited automatically.
m If the PWM frequency is changed in continuous operation with activated dead time
compensation (Dead time compensation factor Z47.50– > 0%) the adaption of the
dead time compensation must be activated after the PWM frequency Z123.1– bit 3 = 1
and therefore the values of the dead time correction table Z123.15– should be measured in this mode.
m The switching of the PWM frequency in continuous operation isn't permitted for the
sensorless synchronous motor.
m The PWM frequency should not be changed during the flying restart of the sensorless
asynchronous motor.
The failures at the implementation of the PWM switching during the continuous operation
in the controller were minimized - however, with reference to control engineering, they

can't be excluded completely. Therefore this option is adequate for simple (not critical)
applications, only.
The instantaneous PWM frequency is displayed in the parameter "Instantaneous PWM
frequency" (Z130.41–). It can deviate from the set PWM frequency >130.15<, if the safety function of the PU temperature mode "PWM reduction" is operated (see ZOverload
monitoring of the power unit– from page 638).
When switching into a lower PWM frequency it must be regarded that the adjusting range
of the output frequency possibly may be reduced.
A change of the set PWM frequency >130.15< during the continuous operation is not accepted as long as the PWM reduction, warning 216 is triggered.
The display parameter Z47.65– specifies the directly acting current controller cycle time.

Phase error delay time
Settable timeout for phase error (Error 1015 „Phase error timeout“). The maximum possible value is specified by Parameter Z129.24– Time phase error (a constant of the power unit specifications).
If Bit 2 of parameter Z130.10– Mode is set, the controller activates a time monitor when
a phase failure is detected. The drive reports warning/error 1047 „Phase failure“. The motor current is restricted to nominal current.
The further behavior is determined by the response which is set in warning/error 1047.

After the phase error delay time has elapsed, if the phase failure condition still exists

warning and switches back to the non-reduced current operation.
m Active braking („Return motion“, „Stop (Ramp-down time)“, „Stop (Quick stop time)“,
„Stop at current limit“, „Controlled stop“, „SS1 stop“)
The drive effects an active error response, changes to „failure“ state upon completion and inhibits the pulses to the power unit.
If the error response will be not finished up to the phase error delay time has
elapsed, the drive generates Error 1015 "Phase error timeout" and inhibits the pulses to the power unit.
Also if the phase error is cleared during phase error delay time, the pulses to the
power unit will be inhibited finally.
m Pulse block
This response is not permitted. In order that the pulses are inhibited fast as possible,
the parameter >130.24< is set to 0.
If Bit 2 of parameter Z130.10– Mode is not set, the phase error delay time doesn’t act.
This parameter is not available at BM2500.

Mains failure delay
A mains failure is ignored within this time.
Warning 1046 Mains failure is generated in general if a mains failure is detected. If the

Different options are possible for the behavior during the Mains failure delay. This options
are defined in parameter Z130.10– Mode.
If the mains is available again within the set Mains failure delay, no error message is generated. The warning is deleted and normal operation is continued.

Motor
3.4.2.1 Motor Identification Plate
Stegmann and Heidenhain encoders provide the option of storing OEM data in their
EEPROM. This memory is used to store the following information in the encoders:
m Notch angle offset
m Machine characteristics
m Encoder characteristics
m Motor ordering code
The data structure of the OEM memory follows the Baumüller standard, as already implemented on the b maXX 4400 and 5200/5300. Thus identification plates can also be read
from encoders which were previously used in b maXX 4400 and 5200/5300 drives and
conversely.
3.4.2.2 Motor Temperature
Three different encoder types can be utilized:
m KTY84/130 (PTC with an almost linear characteristic for precise evaluation of the temperature)
m Temperature switch (motor protection thermistor (PTC) conforming to DIN 44080-082)
m PT1000 (PTC with linear characteristic)
The selection is made using Parameter Z107.37– Temperature Sensor Type. On motors
which have an encoder with an electronic identification plate, the appropriate value is entered at switch-on. On motors without an electronic identification plate, the encoder type
must be entered.
With the KTY84/130 and PT1000 temperature encoders, the current motor temperature
in °C is ascertained and then checked against the two temperature warning thresholds
(Z128.4– and Z128.5–) and if they are exceeded, Warning 710 or 711 is issued. If the
switch-off threshold is exceeded, Error 709 "Motor Overtemperature Detected" is generated. The switch-off threshold in effect is displayed in Parameter Z107.27–. On motors
with an electronic identification plate, the appropriate value is entered at switch-on. The
standard value for Baumüller motors is normally 150°C.
With the temperature switch, the temperature value determined is compared to an internal permanently set switch-off threshold. This switch-off threshold corresponds to a resistance value of 1100 ohms. If it is exceeded, Error 714 "Motor Overtemperature Detected
by Temperature Switch" is generated.
The temperature encoder can be connected either to the encoder input or to the connector X101 provided on the power unit. The setting for the connection is made in Parameter
Z128.2– Temperature acquisition system.

3.4.2.3 Torque limits
NOTE!
If the Nominal Kt Z107.44– is set to zero, then the torque limit is suspended. This
state is achieved by setting the Nominal power Z107.6– to 0 kW. If the Kt correction
factor Z138.23– is set to zero, then the torque limit limits the cross current to 0 A.
The maximum available torque
The maximum torque of the machine is proportional to the available torque-generating
current Z19.8–. This current is calculated by subtracting the magnetizing current set value Z19.9– with the maximum drive current of the drive Z19.6–.
I sq_max =
2
I max – I sd_set
2
Usually, the maximum drive current of the drive Z19.6– is the same the peak current of
the power unit Z6.25–. This current can be reduced by PU overload monitoring.
Additionally, in the field weakening range the torque is limited by the maximum power.
Therefore, the maximum available torque Z138.20– is constant in the base speed range.
In the field weakening range it decreases inversely proportional to the speed.
The symmetric torque limit influences the set value of the cross current controller, which
controls the torque-generating current. However, the generated torque must be limited
and not the torque-generating current. Therefore, the limit for the torque-generating current must be fit to the following equational format.
Torque limit (P138.22)  100

If several limits simultaneously (Z138.6–, Z138.7–, Z138.14–, Z138.15– or Z138.22–)
influence the torque-generating current set value, the lowest one is the decisive value
(see ZFig. 35– (b)).
Particular case synchronous motor with interior permanent magnet (IPMSM)
The torque is calculated from the characteristic map of the IPMSM and from the currents
according to the following formula:
3
T = --- p   PM I q +  L d – L q I d I q 
2
If a torque limit is entered, the maximum Iq current is recalculated from this equitation,
where the torque limit (Z138.22–) corresponds to the torque T.
3.4.2.4 Torque monitoring
Torque indicator Z138.21– displays the internal machine torque. The actual possible machine torque is displayed by the maximum available torque Z138.20–. In order to reach
this maximum available torque, the torque-generating current must not be limited via the
parameters Z138.6–, Z138.7–, Z138.14–, Z138.15– or Z138.22–. See ZFig. 36– for

Defining the torque
Particular Case: Synchronous Machine
If the nominal machine working point (rated torque at rated speed) is only reached, if magnetizing current is applied to the machine, the following must be considered:
If the magnetizing current in the nominal working point is lower than 10% of the rated motor current, then the effects on the torque indicator is about 0.5% of the displayed value.
With magnetizing currents of about 20% of the rated current or above, these effects are
significant (deviation is about 2%).
If the required accuracy of torque indicator Z138.21– is critical due to this influence, it is
recommended, to define the rated data of the synchronous motor at the threshold speed
of field weakening (ID nominal = 0) for unmodified nominal motor current and to enter in
Pnom Z107.6– and nnom Z107.7–.

Max. drive current available
Shows the currently effective limit of the apparent current. It influences the limit of the current torque as well as of the field current. The parameter accords to the minimum value
between the "maximum total current of the drive" Z19.6– and the "External limitation of
the maximum total current" Z138.9–.
19.6
Max. drive current
Settable limitation of the apparent current of the drive influences the limitation from the
current torque as well as from the field current.
The maximum total current of the drive is limited by the "Power unit peak current" Z6.25–:
"Max. drive current" [>19.6<]  "Power unit peak current" [Z6.25–].
NOTE!
m The apparent current limit of the drive can automatically be reduced furthermore,
for example by the PU overload monitoring or the phase fail (see "bit bar of external
current limit" Z138.8– and "External limiting max. drive current" Z138.9–.9 and the
value of the parameter >19.6< is not changed. The current acting limit of the apparent current is displayed in the " Maximum available total current" Z19.5–.
m The "Max. drive current" >19.6< is the scaling size of the standardized current parameter Z166.3– / Z166.4– (current threshold motoric/generator; operation mode

Max. field current amplitude
Display of the maximum amplitude of the field current. The maximum field current for synchronous motors is set via the absolute value of the field current set value (Z19.9–). The
maximum field current for asynchronous motors is set via the limitation of flux controller
(Z146.12–).
The maximum field current amplitude is limited by the maximum total current of the drive
(Z19.6–):
Max. field current amplitude [>19.7<]  0,95 * Max. drive current [Z19.6–]
NOTE!
The amplitude of the field current can be reduced automatically e. g. by the PU overload monitoring or phase fail (see "Bit bar of external current limit" Z138.8– and "External limiting max. field current amplitude" Z138.10–), without the parameter value
>19.7< being changed. The currently effective present limit of the field current is the
minimum value between "Max. field current amplitude" >19.7< and "External limiting
max. field current amplitude" Z138.10–.
19.8

Isd aux = "Max. field current amplitude" Z19.7–.
NOTE!
The "Max. available torque current" >19.8< is the scaling size of the standardized
current torque parameters Z18.50–, Z19.51–, Z138.2–, Z138.3–, Z138.14– and
Z138.15–.

Field current reference value
At an asynchronous machine and if the "Permanent field current" field weakening type is
set (Z142.1– bit 0 = 1) then any field current is permanently applied (lsd set value
Z47.2– = Field current reference value >19.9<). This way the field weakening controllers
and flux controllers are deactivated. For example here the magnetizing current of the
ASM at the measuring point can be entered.
However, the required field current can differ or be lower at field weakening as well as
greater when magnetizing. If the field weakening type was set "at the voltage limit"
(Z142.1– bit 0 = 0) the parameter >19.9< has no meaning for the ASM.
If a synchronous machine is operated in field weakening here a negative current value
must be entered. At a synchronous machine and if the field weakening type "permanent
field current " is set ((Z142.1– bit 0 = 1) here any negative field current can permanently
be applied (Isd-set value Z47.2– = Field current reference value >19.9<). This way the
field weakening controller is deactivated. For example here the required field current at
maximum speed and torque can be entered. The required field current amplitude however can differ from that value if the speed and torques are lower than the maximum values.
If the field weakening type "at the voltage limit" is set (Z142.1– bit 0 = 0) then the parameter >19.9< imposes a field current limit to the field weakening controller and the controlled field weakening characteristic.

Magnetic current
Magnetizing current Id for asynchronous motors. If the motor has no electronic identification plate, the magnetizing current must be entered. If the motor type is not known, Id can
be found from the identification plate / motor data sheet. 
If Id is not known, it can be calculated approximately:
I d = I  1 –  k  cos  n 
2
Where:
|I| = Motor nominal current (Z107.9–)
cos n = Power factor (Z107.12–)

k = 1.0 to 1.3
It corresponds to the nominal current Id at IPMSM (see ZSynchronous motor with interior
permanent magnet– on page 113). The Motor constant K (Z171.12–) used for adjustment of the MTPA characteristic can be calculated from the Nominal current I (Z107.9–)
and the nominal current Id.
107.15
Slip frequency (cold)
The parameter is only relevant to asynchronous motors. The slip frequency of asynchronous motors is temperature-dependent. The following parameter is merely a data point
on the characteristic curve. This characteristic curve is reproduced in the controller; only
the first two data points are used for this (slip frequency when cold at the cold temperature
and slip frequency when warm at the warm temperature). This parameter defines the slip
frequency of the motor at the nominal torque and cold slip temperature (e.g. a cold motor).
The slip frequency when cold must be lower than the slip frequency when warm. If the
asynchronous motor has no electronic identification plate, the slip frequency when cold
must be entered.
107.16
Slip frequency (warm)
For description, see Z107.15–.
This parameter is only relevant to asynchronous motors and defines the slip frequency of
the motor at the nominal torque and warm slip temperature. The slip frequency when
warm must be higher than the slip frequency when cold. If the asynchronous motor has
no electronic identification plate, the slip frequency when warm must be entered.

DANGER!
If the value is changed, the drive automatically loses the notch position search for the
synchronous motor. After change the user must execute notch position search again,
in order to operate a synchronous motor with encoder without danger.
If the synchronous motor is operated sensorless, it can be operated with the new parameter value immediately. As with the sensorless synchronous machines, the parameter
value for asynchronous machines is effective immediately. If the same value is written to
the parameter, which already is in the parameter, then this writing procedure has no effects.

Iq limit motor symmetric
The torque current can be limited symmetrically with this limit, i.e. equal in both torque
directions.
The parameter must be seen in connection with the limits at the torque direction or the
motor and generator operation respectively (Z138.2– and Z138.3–). The less of the set
limits is always effective (symmetrical or mot./gen. and MR1/MR2 respectively).
In contrast to the also symmetrical cyclic torque current limit (Z138.14–) this parameter
is not cyclic writable. Instead it is storable, has the identical standardization as Z138.2–
and Z138.3– and is subject to the hysteresis (Z138.4–) at the determination of the quadrant.

current and ramp-up time must be preset. Then it is accelerated to the desired speed
(Z123.39–) with nominal magnetizing current. Thereby a linear ramp calculated from the
ramp-up time is used. Then the motor successively is supplied with a step size of 1/20 of
the nominal magnetizing current at this speed. Thereby the required voltage is measured.

Synchronous motor with interior permanent magnet
Interior Permanent Magnet Synchronous Motors (IPMSM)
The b maXX 3300 can operate synchronous motors with interior permanent magnet
(IPMSM). The IPMSM has nonlinear inductances. Generally the cross-inductance is
greater than the direct axis inductance. These inductances are depending on Id as well
as Iq.
For operation in an optimum way the current controller must be adapted to the inductances, because the gain of the current controller is directly proportional to the inductances.
The active inductances were gathered directly from the table depending on the current
set values and the current controllers were adapted to these values.
Additionally to the torque of the Lorentz force a reluctance torque exists at the IPMSM
based on the different inductances (T~(Lq-Ld)*Id*Iq). In order to get the maximum torque
for the impressed current (MTPA), also an Id current must be impressed depending on
this torque. The currents were split automatically during controlling, so that always the
highest torque is reached depending on the total current.
3.4.4.1 Commissioning
In order to ensure an optimum in dynamic when operating a IPMSM, the following notes
for setting are mandatory:
– Using a Baumueller motor the data can be loaded from a motor data base. All settings are carried out automatically with ProDrive.
– If no Baumueller motor is used, at first an autotuning (see ZAutotuning of Current
controller– from page 155) must be executed to set the current controller roughly.
– The notch position must be set next.
– The field current can be limited via parameter limit magnetizing current (Z146.12–).
This is important in order to prevent the demagnetization of the motor.
– After this the speed controller must be set. A good setting can be determined with a
control loop analysis.
– Subsequently Lq, Ld and the magnetic flux must be mapped in the controller. Therefore are two options:
n If the parameters are known, they can be loaded via a csv-file.
n If they are not known, an automatic identification can be executed with ProDrive
(see chapter Z3.4.4.2–).
– In conclusion the current controllers must be optimized again. The optimization is
executed according to the table values of Lq(0,0) and Ld(0,0).
3.4.4.2 Identification of the nonlinear parameters
The identification of the nonlinear parameters Lq, Ld and the magnetic flux is executed in
speed control operation. ProDrive executes this automatically. The inductance is measured during ramp-up, in which both currents Iq and Id were kept constant. Therefore the
corresponding inductances can be found for each current combination Iq and Id.
The following settings may be entered:
– Standardization current for the curve family

Configuration
n This is the maximum current as far as the identification is executed. From 0 A up
to this value the currents were varied in ten equal distances and the measurements were executed. 
– Ramp function generator
n The ramp-up time must be set to 0 seconds, so that the speed controller is directly
limited at a speed jump.
– Set value generator
n The set value generator should alternately generate values from 0 up to a sufficient high speed in order to get enough measuring values during the ramp-up.
3.4.4.3 Field weakening at IPMSM
If a voltage limit is reached at the controller, the field weakening controller interferes at
the BM3300. In contrast to synchronous and asynchronous motors a higher torque can
be reached with field weakening at IPMSM, because the additional Id current effects a
reluctance torque.
The required curves of an IPMSM are shown in ZFig. 43–. Without field weakening the
motor works on the MTPA curve (red). If an additional Id current is supplied, the state
shifts left (greater Id current). The Id current can be increased up to the MTPF curve (maximum torque per flux) at field weakening. The maximum torque is reached here at an
available flux. At a greater Id current the motor needs higher voltage to reach the desired
torque. If the available flux reduces further, the maximum Iq current is reduced and the
current pointer always positions itself along the MTPF curve up to the zero point of the
flux. So it is secured that always the maximum torque can be reached.

Description of the Software Modules and Parameters
The field weakening of the IPMSM is implemented via a state machine in the BM3300
(see ZFig. 44–). The state machine changes in the "Flux reduction by Id current" state at
first reaching of the voltage limit. The field weakening controller is initialized to the actual
Id current value, because an Id current is always supplied at operation of IPMSM. The Id
current is here increased up to the Id current of the MTPF curve. If the Id current reaches
the MTPF curve, the state switches in the "Flux reduction by Iq limitation" state. The maximum Iq current is reduced here proportionally to field weakening factor. If the needed Iq
current is less than the half maximum of the Iq current, the state machine switches back
to the previous state.

3.4.5.1 Encoder monitoring
Monitoring of signal amplitude Sin² + Cos²
The controller evaluates the present total amplitude from the sine and cosine traces of the
encoder (Am in ZFig. 45–). At error free operation the sum of the quadrants of the sine
and cosine measuring values is nearly constant. However the signal level is not always
constant, in particular there is a dependence of the angle speed and consequently from
the speed.
The levels for the monitoring of the sin² +cos² value can be set in the parameter Z14.1–
and Z14.2–.
Figure 45:
Sine/Cosine traces and instantaneous amplitude of the encoder signal
Sector monitoring
The sector sequence at the sampling of the encoder traces (sine or cosine signal) is analyzed at this monitoring. Here it is assumed that the sampling rate is at least 4 times the
signal frequency and therefore each quadrant of a signal period is at least sampled once.
Monitoring of square-wave incremental encoder
The levels of the encoder signal are monitored separately at a square-wave incremental
encoder, because a monitoring of the amplitude using sin² +cos² is only restricted possible. The zero trace (zero pulse) is not monitored.

Configuration
NOTE!
m The amplitude monitoring does not monitor for cable breaks and is only in a limited
position to detect any cable breaks that might be present.
It is not guaranteed that an individual break in one of the sin+/sin- or cos+/coslines will be detected by the form of amplitude monitoring implemented.
m It is not possible, if the machine is stationary, to detect a cable break using the indirect method of amplitude monitoring. If might be possible to detect that a cable
break is present using amplitude monitoring, but the machine must first be started
up.
m The amplitude monitoring and the display in the encoder diagnosis of ProDrive is
only possible up to approximately 18 kHz signal frequency (is equivalent to
n [min-1] = 18 kHz * 60 / number of pulses) at a square-wave incremental encoder. Above this frequency only the special square-wave incremental encoder monitoring is effective.
Monitoring of the position actual value
This monitoring is available at Sine-Cosine encoders with digital interface. The absolute
position, which the encoder calculates, is read out at the digital interface (Hiperface,
EnDat, SSI). This value is compared with the position calculated from sine and cosine
traces and is written in parameter Z14.22– Position monitoring error. If this value exceeds the set error threshold Z14.21–, error 428 is initiated:
428 Encoder monitoring: difference between analog and digital position too high
The response time is max. 5 s. Please consider the setting notes for parameter Z14.21–.
Restrictions:
– Monitoring of Hiperface encoder and EnDat 2.1 is possible from firmware version
1.08.
– Monitoring of SSI encoder is currently not possible.
Field Angle Monitoring on Synchronous Machines
The controller determines the pole wheel direction of the rotor with the aid of the motor
model. This is then compared with the pole wheel direction which is calculated from the
encoder used for motor control. When the monitoring is enabled (i.e. the field angle speed
threshhold Z143.8– is not equal to 0), if there is an angle error greater than 45° (electrical), Bit 8 of Parameter Z143.1– is set and the error message
211 Error While Monitoring the Field Angle
is initiated. The pulse enabling is blocked as a result.
Additionally, the field angle monitoring can be switched on and off by setting the field angle speed threshhold (Z143.8–) as a function of the speed set value. If the speed is less
than the field angle speed threshhold (Z143.8–), the monitoring remains disabled.
Field angle monitoring only functions for the encoder which is set for motor control.

3.4.5.4 Encoder correction
Offset- and amplitude error corrections must be done at all encoders. However, the static
encoder error corrections at the sine incremental, the SinCos Hiperface, the SinCos Endat 2.1 and the SSI encoders are advisable upon completion of first correction.
1. Offset and amplitude error correction
Amplitude and offset of the sinusoidal and cosine tracks are measured here. This way is
optimized, that the unit circle of the sine value and the cosine value is centered and has
a 90% amplitude. On the ProDrive page Encoder diagnosis the measured values can be
included for checking. If the measured points are on the predefined green circle, the angle
and speed measuring have been processed correctly.

ProDrive Encoder diagnosis
2. Statical encoder error correction
The encoder signals are subject to tolerances. Therefore, the sinusoidal signals and the
cosine signals are not always conform with an exact sinusoidal function. These tolerances can cause speed vibrations with a frequency of speed*PPR (pulses per revolution).
These tolerances are suppressed by using the automatic statical encoder error correction. The offset values of the encoder tracks are fit, so that the speed vibrations are minimized.
Calculation takes place in speed control. Thereby, the setpoint frequency of speed * PPR
(pulses per revolution) must be constant and they must lie between 30 and 500 Hz.
Measuring checks are made with the circular buffer speed (Z18.22–) and the sinusoidal
track (Z106.24–). The measurement at a SinCos Hiperface encoder with 1024 PPR
count in speed control with a set speed of 10 rpm is shown in the following. The relevant
frequency is 
f = 10 rpm * 1024 = 170 Hz.

3.4.5.5 Excentricity
Vibrations may occur in the speed, with the frequency of the present speed, if the encoder
is not exactly aligned centrically towards the motor shaft. The position error, which was
caused by an encoder eccentricity, cannot be corrected by the positioning controller or by
the speed controller. The position error can be approximated by a sinusoidal function.
Thus, the control error is suppressed on the encoder angle by adding an additional angle
with a sinusoidal function. The amplitude and the phase of this sinusoidal function are automatically determined in ProDrive.

Determination is carried out in current control. The setpoint frequency (speed) must be

3.4.5.6 Resolver synchronization
The resolver can be operated with two different excitation frequencies, 7.8125 kHz and
8 kHz. By using the 8 kHz thereby the resolver excitation can be synchronized on the
fieldbus. Additionally the phase of the resolver excitation can be set to set the resulting
sine and cosine tracks to a certain time.

Synchronization of the resolver
In ZFig. 53– the synchronization of the resolver is represented. Via bit 4 of parameter
Z106.43– the excitation frequency can be set to 8 kHz and activates the synchronization.
The Dsp interrupt is synchronized to the fieldbus and the resolver tracks (blue) are synchronized to the first Dsp interrupt. The excitation (green) is shifted so that the maximum
of the resulting sine and cosine track is synchronous to the Dsp interrupt. The phase shift
between the Dsp interrupt and the accordant maximums are set via the parameter
Z106.52– and accepts values between 0 and 124 µs. Thereby, the excitation voltages of
the amplitude and the phase towards one another can deviate depending on the impedance of the resolver.

If the bit is set, the analog tracks at initialization of absolute encoders with HIPERFACE®-interface are used. This achieves a higher initialization accuracy. The precondition must be an assignment of the digital position information to the analog tracks
according to the HIPERFACE®-specification. The delivery status of encoders have this
assignment. However, this status can be changed by overwriting the digital position of
the encoder.
If this option is set and the assignment is not specified, error 402 occurs at initialization
of the encoder.

Homing sets the M0-Offset automatically (see ZAutomatic setting of the absolute value

It only makes sense to use an M0-Offset with absolute value encoders. Furthermore, the
encoder's range must cover the total traversing range of the drive.
It can be selected at addition of the M0-Offset, whether the range (Z137.2– Number of

not. This is defined in parameter Z106.3– Encoder options bit 7.
If the represented range should be taken into account, an overflow occurs at addition of

Autotuning of Current controller
At present, the following three measurements have been implemented for the autotuning
function:
m Stator resistance measurement,
m Leakage inductance measurement (stator inductance measurement on synchronous
machines)
m Dead time measurement on the power inverter
After the measurements have been performed successfully, the current control circuit can
be self-optimized on command. In ProDrive you can decide whether the modeling parameters used for motor control should be set to the values of inductance and resistance from
the motor data sheet or from the results of the autotuning. The dead time compensation
can also be activated via ProDrive.
NOTE!
With the function "Self-optimization" additional parameters cannot be determined for
the motor model of the connected electrical machine!
BM3000 is not an intelligent measuring device for electrical machines!
With the function "Self-optimization" the control engineering characteristics are determined only. This includes the electrical machine, the cable as well as additional filters
between inverter output of motor and the motor connection terminals.
Dead time compensation is not absolutely necessary when operating with encoder response. Dead time measurement need only be carried out for open loop operation and
the dead time compensation then activated.
Starting autotuning:
m The resistance and inductance measurements can only be started together.
m The dead time measurement can only be started if the resistance and inductance measurements are also activated at the same time.
m After change of switch frequency (Z130.15–) the dead time measurement must be executed again depending on the controller version (see ZDead Time Compensation–
from page 417)!
If desired, the calculation and adoption of the measured resistance and inductance must
be activated in the current regulator parameters (Z123.10– bit 3 = 1) before the measurement. The measured resistance is standardized to 20°C, if a temperature sensor is
connected to measure the motor temperature. If the measurement results are not satisfactory, these parameters can be recalculated from the motor data sheet or be set directly
with other values.
The adoption of the measured motor parameters into the motor control system and the
activation of the dead time compensation is only allowed if the corresponding measurements have been carried out successfully. Otherwise the motor control system uses the
values from the motor data sheet.
The autotuning only has an effect on the current data set.

Time constant of step response
This parameter displays the identified time constant for asynchronous motors. The current level for this is approx. 80% (current rise from 75% to 85%) of the maximum current
(Z123.4–). For synchronous motors the current level is 85% (current rise from 75% to
95%) of the maximum current and from that the value can be compared with the Result
Current Controller Tn (Z123.9–) in order to assess the saturation effects. A clear saturation effect is present if the step response time constant is clearly less than the value of
the Result Current Controller Tn (Z123.9–) parameter. The parameter Z123.9– has in
effect been measured with a current of 50% of the maximum current (Z123.4–).
123.14

Dead time compensation table
Table of the current-dependent correction of the voltage setting based on the measured

The table is displayed graphical in ProDrive on page "Autotuning current controller" by

NOTE!
Up to Firmware version V01.08: The table is valid for the set operating frequency of
the power unit at time of measurement, only. Measurement for the dead time compensation must be made again if the operating frequency (Z130.15–) was changed!
From Firmware version V01.09: If the correction table (dead time) is measured during
the adaption of the dead time compensation according to the PWM frequency is active (Z123.1– bit 3 = 1), the effective voltage of the dead time compensation is corrected according to the effective PWM frequency. Therefore, a dead time
measurement after a change of the PWM frequency is not necessary anymore. However, the best results are generally reached if the used PWM frequency corresponds
to the PWM frequency at the moment of the dead time measurement.

Ks Measurement
The Ks factor measures the accelerating power and is made up of the entire inertia torque
J and of the speed constant Kt of the motor:
Kt
Ks = -----J
Two option to measure the Ks factor are in the BM3300. On the one hand via an acceleration and braking procedure and on the other hand via the FFT module. The speed controller as well as the Ks must be preset. Recommended values are Kp = 60 1/s for the
gain and Tn = 0.3 s for the reset time, whereas the parameter Ks can be preset by about
twice the estimated value or by an empirical value.
During the first measuring procedure the following measuring model is used:
isq   t  = a  d  + b   + c
dt
where:
0  N1    N2
and
1
Ks = --a
in this model. Ks has units of [degreesA/s²] and  is the speed in [degrees/s]. The factor
b is the coefficient of friction (see Z52.9– Load Friction factor). For the determined friction
c at standstill, see Z52.10– Load Friction.
An incorrect Ks factor in the speed controller results in the acceleration feedforward being
incorrect (converted to current) and the controller parameter Kp not being correctly normalized.
The prerequisites for the Ks measurement are:
1
Current controller and motor control have correctly set parameters,
2
Set Value generator and ramp function generator have parameters set,
3
Drive is running with speed control (or position control) with set value generator and
with provisionally set control parameters.
The second option mainly is used if the motor already was included in the application and
may cover a specific distance only. Additionally the erasing and resonant frequency as
well as load inertia and spring and damping constant can be determined at the two mass
oscillating system. Information about this in the ZAutomatic controller and filter setting–
from page 629.

Any function can be selected for the inputs DI1 to DI3.
The function "Pulse enable" is on digital input DI4. DI4 cannot be inverted.
When using the quick stop, the assignment "Quick stop - DI1" is recommended.
Only ONE FUNCTION per input may be selected. With one function, one input linking per
input can be used at the same time (see also Operating Mode for Digital Input 1,

Configuration
3.4.12 Filter
The filter module contains a general digital IIR filter function (IIR = Infinite Impulse Response) which is typically used as an actuating variable filter (Isq filter). The order
(Z29.8–) of the filter (maximum 7) and the filter coefficients (Z29.9– to Z29.23–) can be
freely set as parameters. The transfer function in the z-domain is:
Figure 65:
Equation for filter order
where the z -k are the lag elements about the k-cycle.
The filter module works between the speed controller and the current controller. It can be
switched on and off using the Module command (Z29.1–).
3.4.12.1 ProDrive filter
The filter is set via the individual coefficients. In addition to this ProDrive provides an operating support by which single filters can be parameterized. There are five different filters
under the window Controller  Control structure  Polynominal, which are supported at
parameterization:
– PT1 filter (single or bilinear)
n Low-pass filter with damping from the cutoff frequency which was set, onwards.

Configuration
3.4.13 Fieldbus communication
The fieldbus communication is realized via a separate processor. The basic configuration
is carried out by the fieldbus processor or by the fieldbus master, as well. Therefore, most
parameters within this range are provided for display and diagnostics. Specific settings
must be made in the controller.
It is necessary and also helpful to understand the communication timing in specific cases.
Basic sequence of the different software components in the controller
Figure 68:
Basic sequence of the fieldbus task (fieldbus cycle 1ms, RT0 cycle 250 µs)
The basic sequence of the relevant software components for the fieldbus communication
is shown in ZFig. 68–. The current controller responds every 62.5 µs. The position and
speed controller responds every 250 µs right before the current controller responds. The
fieldbus communication takes place in an own task, which can be interrupted by the current controller or by the position and speed controller.
The beginning of the fieldbus task or of the controller interrupt (after this the fieldbus task
starts) is synchronized to the sync signal of the fieldbus. Hence, the fieldbus task starts
at a sync offset of 0 µs with a time delay of about 30 µs shortly after the sync signal. This
is due to the computing time of the controller interrupt.
In a fieldbus task the set values are read, the actual values are written and then the interpolation for the cyclical position set value specification is calculated. The interpolated position set values are transferred to the position controller with the next position/speed
controller cycle (RT0 cycle).

Transferring the set values from the fieldbus task into the position/speed
controller.
At 250 µs cycle time or greater the set values are transferred in the next RT0 cycle after
the fieldbus task was started.
At 125 µs cycle time the set values are transferred in the RT0 cycle after next one, so that
the fieldbus task is available of more computing time.
Via the parameter Z131.23– Fieldbus options bit 1 can be set that the acceptance of the
set values in the position/speed controller takes place in the beginning of the next fieldbus
cycle only.
Transmission sequence from the fieldbus to the controller
The basic sequence from fieldbus transmission (here EtherCAT) up to the processing in
the controller is shown in the following figure.
Figure 69:
Set value and actual value transfer from the fieldbus to the controller. The configuration fieldbus
cycle 1 ms, RT0 cycle 250 µs, sync offset 0 µs is shown in the example.
In the controller the set value as well as the actual value transmission takes place in the
fieldbus task. The set values (at a sync offset of 0 µs) must reach the controller before the
sync signal takes place. As the fieldbus processor requires time to receive the data from
the fieldbus and then to provide it to the controller, this data must be provided to the fieldbus in time. Alternatively the fieldbus task start and resultant the transmission in the controller can be delayed via the sync offset.
During data exchange between the controller and the fieldbus processor the set values
and the actual values are exchanged back to back. The same applies for data exchange
to the fieldbus (default behavior at EtherCAT: common frame for set values and actual
values).Consequential the actual values are delayed by about two fieldbus cycles.

Configuration
Separated transmission of set values and actual values
Figure 70:
Separated transmission of set values and actual values.
The actual values in the controller can be transmitted separately from the set values.
However, transmission isn't carried out in the fieldbus task anymore, but at the end of a
controller interrupt. The actual values are immediately transferred by the fieldbus processor and provided in the EtherCAT buffer. Thus the dead time for the actual values is reduced.
Hereby, the timing for the fieldbus transmission must be considered exactly in order to
avoid access conflicts when responding to the actual values on the fieldbus.
Time setting of actual value transfer
Figure 71:
Optional separated transmission of set values and actual values.
The transmission time of the actual values to the fieldbus processor can be determined
in the parameter Fieldbus options (Z131.23–), separately. Now transmission takes place
at the end of a controller interrupt and not in the fieldbus task anymore. It is possible to
set the controller interrupt carrying out the transmission. Thereby, the controller interrupt
starts to count where the fieldbus task is carried out, too. A setting of 0 controller cycles
means that the actual values are transmitted in the interrupt, where the fieldbus task will

Description of the Software Modules and Parameters
be started after that. This means that with this setting the actual values are transmitted
right before the set values are read.
The exact time for actual value transmission to the fieldbus processor alternates because
of the controller interrupt's computing time. Therefore, a time frame of 62.5 µs is set. In
the example shown a controller cycle of 5 was set. Therewith, transmission is carried out
within a time frame of 312.5 µs to 375 µs after the sync event has taken place (at sync
offset 0 µs). Additional time must be calculated for the transmission to the fieldbus, as the
fieldbus processor requires time to receive the data from the controller and to transmit it
onto the fieldbus buffer.
3.4.13.1 Parameter IDs for the Real Time Lists
The contents of the real time lists in the controller are configured at system commissioning by means of a service channel. These are then exchanged in real time. For each direction (Consumer and Producer) there exist two lists in which the values of a maximum
of 16 parameter Ids can be transferred in each case.
The IDs of the Producer and Consumer lists are represented in ProDrive as a two-dimensional array[2][16] in each case. The lists can then be opened simultaneously in ProDrive.
All the data can thus be visualized in a clearly laid-out manner.
3.4.13.2 Access Counter for each Real Time List
The number of accesses to the Producer and Consumer lists is represented in each case
as a one-dimensional array[2]. The lists can then be opened simultaneously in ProDrive.
All the accesses can thus be visualized on-line in a clearly laid-out manner. The access
counters are writable parameters, so that the counter statuses can be set externally, e.g.
to 0.
Using a further two parameters it is possible to display separately for Producer and Consumer, which list was last accessed in each case.

The time (in controller cycles) to transmit the actual values to the fieldbus
processor
The transmission of the set values and the actual values from/to the fieldbus processor
normally takes place in the fieldbus task. For special applications individual time settings
can be configured for actual value transmissions.

3.4
Configuration
The transmission occurs in line with a controller interrupt. The time is set in a grid of controller cycles (62.5 µs).
A setting of 0 controller cycles means that the actual values are transmitted in the interrupt in which the fieldbus task is started in the following. In this way the reading of the set
values follow close upon the transmission of the actual values due to this setting.

Profinet device name
This parameter contains the Profinet device name (max. 240 characters). ProDrive displays this parameter as text on the Configuration / Fieldbus slave page, if the fieldbus of
the connected controller is a Profinet type.
131.52
Error counter fieldbus actual values
Error counter for access conflicts at actual values.
The counter is incremented, if the fieldbus firmware did not retrieve the actual values. If
the fieldbus is in operational state and the drive is synchronous with the fieldbus, the error
1937 is set at exceeding of threshold Z131.55–.
131.53
Error counter fieldbus set values
Error counter for set value failures.
The counter is incremented at every set value failure. If the fieldbus is in operational state
and the drive is synchronous with the fieldbus, the error 1938 is set at exceeding of
threshold Z131.56–.
131.55
Max error count fieldbus actual values
Error threshold for access conflicts at actual values.
This parameter configures how many access conflicts (actual values have been not retrieved) are necessary to set the error 1937.

3.4.14 Measuring encoder function
The Measuring encoder function can be used to store the position actual values of Encoder 1 to different external signals.
Different settings may be selected as trigger signals for measuring encoders. When the
trigger signal occurs, the current position actual value of the corresponding encoder will
be stored and shown in the assigned measuring encoder display parameters.
The accuracy of the measuring encoder is the accuracy of the encoder system that is
used:
m With rectangular incremental encoders, the resolution per revolution corresponds with
the quadruple of the line number.
m With SinCos® encoders and sine incremental encoders, the analog information from
the sine and cosine tracks is also evaluated.
m Only the information from the analogous evaluation exists for tilt encoders.
The following events may trigger the storage:
m Rising and / or falling edge at digital input TP1
m Rising and / or falling edge at digital input TP2
m Zero pulse of a encoder. This function is only possible with rectangular or sine incremental encoders.
m Zero pulse of a encoder in connection with an additional qualification signal (High or
Low level) at digital input TP1 or TP2.
A one-time or continuous storage is possible for each trigger event (e.g. rising edge at
digital input TP1). If a trigger should be issued for a rising or falling edge of a digital input,
a minimum edge distance of at least 4 µs must be observed due to the limitations of the
digital I/O evaluation. The minimum edge distance is extended up to 500 µs, if the filter
for suppression of bounce influences is switched on.
Only the first measurement will be displayed for single measurements ("one-time triggering"). Triggering will then be deactivated and additional trigger events will therefore be ignored. The availability of the measured values will be shown in Parameter 124.3 (Status).
124.2 (Measuring Encoder ActCmd) can be used to reactivate an already configured
(124.1 Measuring Encoder ConfMode) single measurement and the existing measured
values for the applicable trigger event will thereby be deleted.
With continuous triggering, the first measurement within the sampling cycle (1 ms) is always displayed. If additional trigger events follow within the same sampling cycle, they
will be ignored. The first measurement within the next sampling cycle will overwrite the
values of the previous one. The availability of new measured values will be displayed in
parameters 124.3 (Status, after initial measurement) and 124.4 (Status 2, Toggle Bit after
each new measurement).
With triggering from a digital input, the allocation positive/negative edge is dependent on
the direction of revolution. The measured values of the positive edge at positive direction
of revolution are equal to the measured values of the negative edge at negative direction
of revolution. The measured values of the negative edge at positive direction of revolution
are equal to the measured values of the positive edge at negative direction of revolution,
and where necessary adding the measuring inaccuracy due to the encoder’s resolution.

3.4
Configuration
With triggering from zero pulse, the measured value of the positive edge is independent
of the direction of revolution, the measured value of the negative edge differs depending
on the direction of revolution by maximum ± ¼ number of pulses.
So only the positive edge should be analyzed by triggering from zero pulse.

These two freely programmable PID controller can be used for realization of user-specific
feedback control problems.
m The cycle time is 250 µs.
m The single controllers (P, I, D) can be switched on and switched off separately by
selection of the corresponding bits in the PID controller mode.
m The PID controller can be synchronized with current, speed or position controller, i.e.
the controller is only then activated, when current, speed or position controller are
active.
m Set value, actual value and output can be freely selected via freely configurable
source or target parameters.
Set value and actual value can be specified alternatively via open-loop control +
fieldbus or analogous inputs. The output can be read out via open-loop control +
fieldbus or analogous output.
The freely programmable controller can be configured as P, PI, PD, PID, I, ID and D controller by selection of the corresponding bits in the PID controller mode. The activation of
the PID controller can be synchronized with current, speed or position controller by selection of the bits in PID controller mode.
Algorithm
The following transfer function is true for the PID controller:
Kp
Ys
G  s  = ----------- = Kp + ------------- + Kp  Tv  s
Us
Tn  s
Kp = P - gain
Tv = Derivative time
Tn = Integral action time
With
Kp
Ki = ------Tn
and
Kd = Kp  Tv
we obtain:
Ki
G  s  = Kp + ------ + Kd  s
s
This means that Kp is effective for the D and I controller even then if the P controller is
inactive.

3.4.16 Master-Slave Torque Coupling
By means of the function „Master-Slave Torque Coupling“ the loading of two drives, which
carry load together, can be divided in a defined ratio.
Structure of the control
A direct communication between the axes is necessary for this function via a fieldbus
(cross communication between the axes or via a controller). In any case a controller is
required which sends the same speed set value to the involved axes.
Requirements:
The following requirements must be fulfilled for the torque coupling:
m Drives are rigidly coupled
m Master and slave are in speed control
m Master and slave get the same speed set value, e.g. over EtherCAT
m Cross communication between master and slave is possible
A compensating controller on the slave drive calculates an additional speed set value
from the torque set value of the master (receiving over cross communication) and the
torque set value of the slave corresponding to the torque weighting. Over a rigid coupling
the torque are set corresponding to the torque weighting (see ZFig. 76– on page 232 or
ZFig. 77– on page 233).
The coupling is activated on the master (Z147.1– Bit 8), slave-side this setting is efficiently not before master and slave are enabled (Z147.3– Bit 4 = 1), because the servo loops
are closed then.
NOTE!
The slave can accelerate possibly up to the overspeed limit (Z6.5– or Z6.6–), if the
mechanical coupling is removed during the torque coupling is active (Z147.3–
Bit 4 = 1).
For stressing the drives in standstill and if applicable also during the motion an additional
torque init stress can be connected.
Two options are available for the connection of the torque init stress:

control and sends up the telegram to the drive slave. The drive slave reads this values in
the same bus cycle as its set values. Therefore
m the drive master must be located physically in the EtherCAT cycle in front of the drive
slave in order that the drive slave gets the actual values.
m the coupling command master, the torque set value master and torque init stress actual value master (optional) must be mapped in the drive master and the drive slave
in the same address area.

3.4.17 Friction compensation
3.4.17.1 Description of the friction compensation
The dynamic of a feed axis is influenced negatively from static friction (dry friction) at start
or inversion of the direction. The friction compensation enables the compensation of the
static friction by connecting an additional torque set value which is dependent on the moving direction and speed.
Functionality
In principle the friction compensation is, that the known static friction part is compensated
via an additional torque set value and must not be balanced by the speed controller.
Thus an improvement of the controller behavior (lower position error) can be obtained especially at reversal of the moving direction. This causes an increase of the drive control’s
accuracy.
A certain compensation of the friction is achieved with the connection of a correction signal to the internal speed set value.
HINWEIS!
A speed controlled or position controlled operating mode must be activated (see
Z109.1–) for friction compensation.
A correction signal with selectable progression is connected depending on the set value
or actual value speed of the drive.

Ramp with PT1 filter and response
Figure 83:
Friction torque compensation with PT1 filter and response
This friction torque compensation is symmetrical to speed 0 and is executed with the
speed set value only. A difference is made between three cases:
– Starting the control: Actual current value is 0 and no default setting of direction.
n Setting via output value 1 (Z154.5–)
– Start-stop: Actual current value doesn't reach 0. The values, which are added are
lower. The curve is flatter than the previous one; the friction torque compensation is
lower. Friction torque compensation often isn't necessary.
n Setting via output value 2 (Z154.6–)
– Reversal: Actual current value is negative. The static friction torque as well as the
dynamic friction torque (from the other direction) must be compensated.
n Setting via output value 3 (Z154.7–)
The slope of the friction torque curve is calculated via the lower speed threshold
(Z154.3–). Additionally to the slope a PT1 filter is effective with the time constant of parameter Z154.10– and the speed deviation is feedbacked and it is responded to the deviation. If the speed actual value is greater than the speed set value, the compensation is
stopped. The compensation is continued not until the speed deviation drops again.
If the speed decreases to 0 rpm, the actual compensation value is added to the integral
term of the speed controller and is reset to 0 subsequently. The result is no change of the
torque set value and the friction compensation function can be started again.

Configuration
Figure 84:
Speed controller gain at stick-slip effect
In addition the controller responds to the stick-slip effect, i.e. if the friction moment drops
abruptly at exceeding of the static friction. This adaption is switched on not before at least
80% of the friction torque is reached and responds, if the actual speed increases faster
than the set speed over several cycles. The speed controller is adapted and the compensation falls via the PT1 filter to the output value 2 (Z154.6–), if the direction of revolution
is reversed.
At the speed controller the P term as well as the integral term are amplified shortly by the
same factor (Z154.11–), in which the factor drops down linearly to the speed set value.
3.4.17.2 Identification of the friction torque curve
The friction torque compensation with PT1 filter and ramp can be identified automatically.
For this the motor must move between a positive and a negative speed with a slowly increasing ramp. The settings and the identification can be done automatically in ProDrive.
The identification is started via bit 9 of parameter Z154.1– and their status is displayed
in parameter Z154.12–.

Sync tolerance
Tolerance range for the synchronization signal. These values set the maximum permitted
jitter for the synchronization signal. It also sets the range within the drive synchronously
to the fieldbus.
156.4
Sync offset
Offset between the fieldbus synchronization signal and the controller cycle. Positive values generate an offset of the controller cycle.
This parameter is set automatically. Manual setting is possible, if manual setting is activated in the parameter „Synchronization Mode“ (Z156.1–).
According to fieldbus cycle time and configuration of the EtherCAT master, a manual setting may be necessary, in order to exchange data between the drive controller and the
fieldbus connection without problems.
The Sync Offset must be set, so that no access conflicts occur on the internal DPRAM.
This can be controlled via the parameters Z156.15– to Z156.19–. Write access fieldbus
and read access DSP must be at least 50 µs apart. The same applies to write access
DSP and read access fieldbus.
156.5
Fieldbus cycle
Measured interval-length of the synchronization signal.
156.6
Fieldbus jitter
Measured jitter of the fieldbus synchronization signal (deviation of the set interval-length).
156.7
Sync error
Current phase error between synchronization signal and the controller cycle.

3.4.19 Configurable status word
With this function single bit information with up to 16 parameters can be copied into a
common status word (Z165.2–).
The following settings are possible for each status bit ("channel")
m Parameter number of source
m Bit number
m Logical bit
Via the parameter Z165.6– Latch the state of short-time bits of the parameter Z165.2–
is specified (OR function).
NOTE!
The cycle time of function is 1 ms. States, which occur for a short time interval will not
be detected reliably by the configurable status word or the latch. The configurable
status word is generated at the end of task RT1. That means that all other operations
of this task have been processed.
Furthermore adjacent bit pairs of the parameter Z165.2– can be combined with logic operations. The structure of the operations is predefined (see ZFig. 85–).
The following boolean operators are available: AND, OR, XOR, NAND, NOR and XNOR.
The operation results can also be mapped to the configurable bits 14 and 15 of the
Z108.3– Status word 1 of the drive manager. Here the information is available with a delay of 1 ms. This function is described in the parameters Z108.9– to Z108.12–.

3.4.20 SoftDrivePLC
3.4.20.1 Overview SoftDrivePLC
For controller version V01.07 and higher a restricted PLC functionality exists in the firmware. Herewith programmable operations and accesses to controller parameters can be
executed.
The SoftDrivePLC enables simple assignments directly on the drive (without needing a
PLC option module).
The SoftDrivePLC of the b maXX drive is provided in two variations
m Standard version (free)
m Full version (extra charge)
Limitations of the standard version compared with the full version
m Only one event task and the default task is possible
m Fastest event task RT0 is not possible
m Length of the executable code within the task is reduced
The program ProProg 5 is used for operation of the full version. The standard version can
be operated with ProDrive as well as with ProProg5.
NOTE!
Controllers with full version of the SoftDrivePLC must be ordered explicitly. The Baumueller type code shows whether this functionality is integrated or not.
If the full version is available, an identifier "-Exx-" exists in the device type code at which
xx must be an odd number.
Example:
BM3XXX - XXXX - XXXXX[-X] - XXXXX [-S0X] - XX [-XX] [-E01] [-#XX]
The full functionality of the SoftDrivePLC is available at a controller with this type code.
The SoftDrivePLC is programmed with the ProProg V5.x software in the IEC-61131 language Structured Text (ST).
3.4.20.2 Function
With the SoftDrivePLC parameter accesses links can be executed directly at the controller without using a PLC option module.
Typical applications for the SoftDrivePLC:
m Computing of scalar controller parameters
m Access to digital, analog inputs / outputs
m Weighting of controller values
m Error management, etc.

3.4
Configuration
The following direct access is possible to controller parameters via the SoftDrivePLC:
m Read access to all 16 bit and 32 bit scalar controller parameters including floating
point parameters,
m write access to all 16 bit and 32 bit writable scalar controller parameters,
m access to data set parameters depending on active data set,
m access to instantiated parameters
3.4.20.3 Limitations
The following limitations apply for the SoftDrivePLC:
m Supported data types: BOOL, WORD, DWORD, SINT, INT, DINT, USINT, UINT,
UDINT, REAL
m Access to scalar parameters only
m At present no function calls or function block calls possible
m It follows that there were no standard function blocks defined in IEC-61131 available, e.g. edge detection (R_TRIG, F_TRIG), timer (TP, TON, TOF), counter (CUT,
CDT, ...) etc.
m No motion function blocks or other technology functions available
m No fieldbus master control
m In Program Organization Units (POU) called by interrupt events there are no back
loops allowed (i.e. no loop instructions e.g. FOR, WHILE, REPEAT applicable)
m The memory size for local variables is 500 bytes. In this memory operands of the
types bool, byte, word or double word can be set arbitrarily, as long as the sum of
the memory requirement of the operands does not exceed 500 bytes.

m Number and characteristics of tasks are fixed.
m No retain data
m No breakpoints, single step operation, single cycle operation, no forcing of I/Os possible.
m The controller PLC saves a correct translated project always in the flash memory. It
is not possible to keep a boot project in the flash while working with another project
in RAM.

3.4.20.4 Tasks
The SoftDrivePLC features from V01.07 the following tasks which one or more POUs
could be assigned:
m default task (lowest priority in real time operating system of the controller),
m RT0, RT1, RT2, fieldbus task, write events to parameter.
The required calculating time of the default task can be read in parameter Z170.5–.
All tasks can be activated or deactivated separately via controller parameter.
Parameter Z170.1– configures, whether the SoftDrivePLC should execute a cold start at
once when switching on the controller.
3.4.20.5 Programming interface
The Windows program ProProg Version 5.x or ProDrive are the programming interfaces
for the SoftDrivePLC.
These programs are able to
m write and administrate PLC projects
m load projects in the controller and run projects
m control the PLC (cold start and hot start)
m display controller variables during run-time in appropriate debug windows
Programming via ProDrive
ProDrive provides a framework for a PLC project. Such a project is part of the ProDrive
project and is saved automatically in a sub-directory associated on the b maXX drive within the ProDrive project. The PLC project file (*.plcprojx) is compatible to ProProg5. The
PLC project files are included in case of copying or zipping a ProDrive project.
The Build process generates a PLC program file (*.pro) which is saved in a sub-directory
associated with the b maXX drive within the ProDrive project. This file is then transmitted
to the drive and activated. When executing an upload or download of a parameter set via
ProDrive, the PLC program file is transmitted also and saved using the same file name
but another file extension (*.pro)
NOTE!
The parameter module, the SAF modules and the Control Panel do not support the
PLC program file.
Worksheets
For programming the SoftDrivePLC ProDrive provides a variables worksheet and two
code worksheets .
The variables of the PLC project can be defined with an ST editor in the variable worksheet. The drive parameters which can be inserted in the variables data sheet by double
click or drag & drop are to be found in the toolbox at the right window frame. The toolbox
also provides filtering drive parameters by name or by number.

3.4
Configuration
For programming the two tasks ProDrive provides a separate code worksheet. The programming is done with the help of an ST editor. The toolbox at the code worksheet contains beside the list of defined variables, the keywords and functions as well as the
commands for possible type changes. The entries can be inserted in the code worksheet
by double click or drag & drop. Each entry provides a context menu for opening e.g. help
or other functions.
Error handling in the controller
Overview of the PLC relevant errors, which must be considered by the controller:
m Static errors:
n Load error of the PLC project file (boot file)
n Compile error of the neutral intermediate codes

Error in the intermediate code or not supported command sequence

Violation of restrictions as returns in real time tasks
m Run-time errors
n Task timeout (watchdog error)
n Array boundary check errors
n Division by zero - is not evaluated currently - the result of division by zero is zero
n Errors according to return values of the executing parameter access functions
n Bracket errors

3.4.21 DS402 Factor Group
3.4.21.1 General information
The DS402 Factor Group (CiA CANopen Drives and motion control profile Part 2: Operation modes and application data) is supported in order to adapt to user-specific units.
Position, speed and acceleration weightings can calculate or recalculate the most important drive parameters.
A conversion and a write access to the accordant drive parameter are executed by each
write access to the writable parameters. Read only parameters are updated cyclically.
The Factor Group is activated for all axes available in the device by setting bit 14 = 1 in
parameter Z131.9– (Fieldbus slave settings). Scaling can be adjusted separately for
each axis.
The DS402 scalings are calculated as follows (the corresponding DS402 object number
is in brackets):

3.5.1
Drive management
The drive manager manages the important system resources of the drive. These include,
among other things, the complete control of the device in the various operating modes,
switching between modes, error handling, the management of all communications interfaces, etc.
The control of the drive is effected by means of a state machine which is operated via the
control word Z108.1– and hardware control inputs. At the same time, control is also possible using only the hardware inputs, i.e., without activating the control word. To do this,
the bits for motor control in the Communications Source parameter Z108.7– must be appropriately cleared.
The state machine for device control (see ZFig. 90– on page 285) and the commands in
the control word conform to the Drivecom/CANopen standard. The control word Z108.1–
and the corresponding commands are explained in detail in the parameter description.
The following hardware control inputs are present:
m Quick stop input (SH):
n Terminal: X2 Digital Inputs 
Using Parameters 116.2/116.8/116.14/116.20, any chosen digital input can be selected as the input for the Quick Stop. For normal operation, a High level (if input is
not inverted) is required. If no input is selected, the signal will always be seen internally as set (High). A Zero level on this input (if input is not inverted) initiates the
Quick Stop response.
m Pulse enable (IF):
n Terminal: X2 Digital Inputs Pin 5 
Enables the pulses for PWM. This input acts directly on the power unit driver. If a
Zero level is applied here, no pulses can be output by the power unit.
m Controller Enable (RF):
n Terminal: X2 Digital Inputs 
Using Parameters 116.2/116.8/116.14/116.20, any chosen digital input can be selected as the input for the Controller Enable. If no input is selected, the signal will
always be seen internally as set (High). The Controller Enable takes place together
with the Pulse enable or via the control word command.
m Input error reset (FR):
n Using Parameters 116.2/116.8/116.14/116.20 any chosen digital input can be selected as the input for error reset. A rising edge on this input (if input is not inverted)
initiates an error reset.

m Parking shaft
If a controller in the Fieldbus network is operated without a motor or encoder, the output
of errors (display, error LED) can be suppressed by activating the "Parking shaft" display
state.
In the "Parking shaft" display state, a "P" is displayed and the error LED remains off. This
is also the case when errors occur. However errors and the drive state continue to be signaled as usual by means of the status word and the error parameters. The transition to
other drive states as State 1 (Switch-on Inhibit) or State F (Error) is not possible.
After the "Parking shaft" display state is exited, the actual drive state (1 or F) will be displayed again. Error and warning messages will be transmitted and displayed as usual
(display, error LED). Changing to other states will be possible again.
The "Activate Parking shaft" and "Cancel Parking shaft" requests are transmitted using
the Parking shaft Control Word parameter Z108.20–. The state and errors for the requests are signaled by the Parking shaft Status Word parameter Z108.21–.
The controller will only accept the "Activate Parking shaft" command if the following conditions have been satisfied:
n Controller is in Drive State 1 (Switch-on Inhibit) or Drive State F (Error)
n Drive is at a standstill (N=0 threshold under-run)
The "Cancel Parking shaft" command will be accepted if the controller is in the "Parking
shaft" display state.
If the controller is switched off in the "Parking shaft" display state, this state will be re-established at the next switch-on.

m Bit 13:
For all operating modes: inhibit operating mode changeover
To avoid inconsistencies between the set operating mode and the mode-dependent bits,
the mode changeover can be inhibited selectively. When the bit is set, the set operating
mode remains active. Any intended change to the operating mode will only be adopted
when the bit is cleared. A new operating mode can thus be activated synchronously with
the control word. The instantaneous state of the mode changeover is indicated in
Z108.5– Status Word 2.

Bit 3: Error
The controller sets this bit as soon as an error (Parameter 100.2 > 0) which triggers an
error reaction from the drive appears. The bit remains set during the error reaction and
in the error state, and is only cleared when the error is successfully reset. The error
LED lights as soon as this bit is set.
Bit 4: Main supply voltage / DC link voltage present
Mono unit with its own power supply:
The bit is set when the main supply voltage is present on the power unit and the DC
link is loaded. It is cleared if the main supply fails. This bit is always updated independently to the device state.
Bus axis (without its own supply; DC link is generated externally by a mains rectifier
unit): 
If the evaluation of the "Operationally ready" signal is switched on (Parameter 140.1
Bit 0 = 0 and Bit 10 = 0) and if the supply and the bus axis are linked together via the
signal bus, the following applies:
If the DC link of the mains rectifier unit is loaded and the mains rectifier unit is operationally ready, the mains rectifier unit reports "Operationally ready" over the signal bus.
Then Bit 4 is set; otherwise it is cleared. This bit is always updated independently to
the device state.
If the evaluation of the "Operationally ready" signal is switched off (Parameter 140.1
Bit 0 = 1) or (140.1 Bit 0 = 0 and Bit 10 = 1), Bit 4 is always set.
Bit 5: Quick Stop or request for Quick Stop active
The bit is active low and is cleared as soon as a Quick Stop response is initiated via
the "Quick Stop" control word command or via a hardware input configured for "Quick
Stop" (see Parameter Z108.8– DI_StatusDrvControl (Status digital inputs drive manager)). When the "Ready to Switch On" state is reached, the bit is set. If "Remain in
Quick Stop" is selected as the behavior for the Quick Stop response (Parameter
Z108.13– QuickstopCode (QUICK STOP reaction code) Values 5 to 8), this bit remains cleared for as long as the drive is in Quick Stop. The bit is set once more as soon
as the drive is enabled again or the "Ready to Switch On" state is reached as a result
of a command.

Bit 7: Warning
This bit indicates when a warning or an error which does not result in any error reaction
is present in the controller. This state can be recognized externally by the flashing of
the error LED.
Bit 8: Status of ramp function generator is Stop
m Speed control (Operating mode -3) and speed setting (Operating mode 2): 
This bit indicates that the ramp function generator has been stopped and its output is
therefore frozen.
m Coupled operation (operation mode -12) 
1: A reloaded curve is ready to be activated. 
0: A reloaded curve was activated and there is no curve available anymore
Bit 9: Remote
This bit is not yet supported at present.
Bit 10: Set Value reached
This bit is cleared in the inhibited state in all operating modes
m Position control (Operating mode -4) and synchronous operation (Operating mode -5): 
The bit is set immediately if neither of the two position contouring error monitors has
detected an overshoot of the set limits (Parameter Z143.1– Monitoring status, Bits 0
and 4 are both 0).
m Speed control (Operating mode -3) and speed setting (Operating mode 2): 
The bit is set if
– the output value of the ramp function generator is equal to the input value and
– the speed controller deviation is less than the preset limit and the ramp function generator is reporting "Set Value reached". During active braking procedures (Quick
Stop, Inhibit Operation) the bit is set as soon as the drive is at standstill (Parameter
Z6.1– "Speed=0 message").
m Manual drive operation (Operating mode 5): 
The bit is set if the output speed set value (Parameter Z119.8–) has reached the specified jogging speed (Parameter Z119.4–).
m Reference run operation (Operating mode 6): 
The bit is set in the following cases:
– Reference run has completed successfully (bit 12 is set additionally)
– Reference run is not yet started or interrupted (command hold) and the drive is at
standstill (then bit 12 is deleted)
– Error at reference run and drive is at standstill (bit 13 is set additionally)
An overview of the bit combinations for the reference run is located subsequent to the
table „General Overview of All Operating Modes“.
m Spindle positioning (Operating mode -6):
The bit is set as soon as the position actual value is in the set position window for the
set position window time. The bit will be deleted when the drive is not any longer in the
positioning window.

Word 1 Bit 8, Hold:
m Target Position Setting (Operating mode 1):
– If Hold = 0: 
The bit is set as soon as the actual position value is in the preset positioning window
for the preset positioning window time. The bit is cleared when the drive is no longer
in the positioning window.
– If Hold = 1: 
The bit is set as soon as the axis has come to a stop. For this, the set value setting
and the drive must be at a standstill (Parameter Z6.1– "Speed-0 Message"). The
Hold function is only implemented in the Target Position Setting mode (Operating
mode 1).
Bit 11: Internal limits active
The bit is set if an internal limit is active, for example current limit, speed limit, hardware
and software limit switches. This bit is always updated independently to the device state.
Parameter Z108.17– "Mask for Status of Internal Limits" can be used to define which internal limits should be displayed.
Bit 12:
m Speed control (-3) and speed setting (2): 
The bit is set if the n=0 threshold is under-run. This bit is always updated independently
to the device state.
m Target Position Setting (Operating mode 1): 
The bit is set to acknowledge a new set value if the control of the positioning is effected
by means of "New Set Value".
m Reference run operation (Operating mode 6):
The bit is set if the reference run has completed successfully with the home position
being set. 
The bit is deleted if the start bit in the control word (bit 4) is canceled.
m Spindle positioning (Operating mode -6)
1: Start-Command-Acknowledge 
The start of a sequential positioning will be acknowledged when the controller has recognized the command and positions. For this purpose the preceding spindle positioning must be completed and then an increasing edge must be recognized in the startbit. This handshake is made only at sequential positioning and at start after spindle positioning error.
m Position control (operating mode -4): 
1: Target posiiton effective 
The bit is set, if the drive follows the set value (target posiiton) from the cyclic transmission, i. e. the set value is written to the input of the position controller. The bit is deleted,
if the drive ignores the cyclic set value. 
This is the case at

Delay for Quick Stop input
Settable delay for the response to the activation of Quick Stop by the Quick Stop digital

Time for reducing torque
This parameter can be set to provide smooth torque reduction using controlled braking
procedures. After the drive has been braked to Speed 0, the internal torque limit is reduced linearly to 0 over the set time and the drive is then inhibited. This smooth reduction
of torque is effective for all braking procedures controlled by the drive manager, i.e., for
the "Inhibit Operation", "Shut Down Drive" and "Quick Stop" commands, provided a braking procedure with subsequent transition to an inhibited state is set as a response to the
corresponding command. Furthermore the smooth reduction of torque also operates for
error reactions where a braking procedure is initiated.

Data Set Management
The device data set management is described in this chapter. You will learn how to create
and change over data sets without ProDrive.
All the parameters which are assigned to the data set management system can be found
at ZParameter overview– from page 320.
3.5.2.1 General
The total configuration, thus all storable parameters, of the device is referred to as Parameter set. The parameter set includes the axis independent parameter and the axis
dependent parameter of all axes.
Tha data set dependent parameter of an axis are referred to as Data set.
The parameters for configuring the device are stored in its Flash memory.
Some of these parameters are implemented as data set parameters, i.e., up to 7 different
configurations can be stored. It is also possible to switch between these data sets during
operation.
3.5.2.2 Command interface
The data set management system can be accessed via ProDrive or via Fieldbus.
The following actions are possible:
m Storing parameter set
m Loading parameter set
m Creating and deleting data sets
m Initializing data sets
m Switching between (already created) data sets
m Copying data sets
m Storing data sets
m Loading data sets
A command is activated either by ProDrive or by writing a command code to the Command parameter Z105.1–. Additional auxiliary parameters supplement the command interface.
When operating with ProDrive, data set command codes and data set auxiliary parameters must be ignored as they automatically take over the user interface.
The parameter Z105.2– Status displays the instantaneous processing state of the command interface and also any error messages from the previous command.

3.5.2.3 Organization of the parameters in the data sets
Within the device there are seven separate memory areas for parameters that have the
"Data Set" attribute (DS 1 to DS 7).
In addition there is a "window" which represents the current active data set (DS 0). One
of these seven data sets is always selected active. By writing to Parameter Z105.6– Active Data Set Number, Data Set 1, 2, 3, 4, 5, 6 or 7 can be selected to be active, hence it
is possible to switch between the data sets. In so doing, the window moves from DS 0 to
the memory area of the activated data set.
Example: 
Data Set 3 is activated. 
The "window" for the active data set addresses Data Set 3.
Figure 91:
Active data set
Basically, only data from the active data set (DS 0) can be accessed via external option
modules or Fieldbuses.

3.5.2.4 Delivered state
When delivered, only Data Set 1 is created. The other data sets DS 2 to DS 7 are deleted.
The active data set (DS 0) is Data Set 1. All parameters have their standard values.
Switching to another data set is not possible.
After the device is configured, the parameters in the device should be saved. If an error
occurs while saving (e.g. as a result of switching off the device during the programming
procedure), the device writes the standard values (default setting) to the parameters
when switched on again.
3.5.2.5 Switch-On behavior
After the b maXX® is switched on, all parameters are loaded with the stored data. The
device activates Data Set 1. Unconfigured data sets are set to default values.
3.5.2.6 Changing, loading, copying and storing parameters
Changes to parameter values (e.g. by ProDrive or via a Fieldbus) only affect the device's
working memory. If changes are also to be preserved after the next switch-on of the device, the parameters must be explicitly stored in the device. All the parameters in all the
created data sets are always stored.
With the aid of data set commands, the values of parameters in created data sets can be
loaded individually or completely into the working memory.
The data set copy function permits copying of the parameter values from a created source
data set to a different target data set. If the target data set has not been created yet, it will
be automatically created by the device. If the target data set has already been created,
the original parameter values will be overwritten.
Using the ProDrive Up/Download function on the "Data Set Management" page, parameters can also be saved to a PC data storage medium or written back to the device.
3.5.2.7 Identification of parameter set and data sets
There is the parameter Z105.11– for identifying of the complete parameter set for a device.
For identifying individual data sets the following parameter are available:

3.5.2.8 Functions of the Data Set Management System
NOTE!
The drive must be switched inactive during loading of the data sets.
Data Set Management 
Commands
The Data Set Management System has the following functions 
(can be set in Z105.1– Command):
m Reset the Data Set Management System
m Write parameter set to Flash memory
m Read parameter set from Flash memory
m Delete parameter set in Flash memory
m Set standard values for the active data set
m Set standard values for all savable parameters
m Create Data Set <n>
m Delete Data Set <n>
m Copy Data Set <x> to Data Set <y> (from RAM to RAM)
m Load Data Set <x> from Flash memory
Status of the Data The status parameter Z105.2– Data Set Management Status is used to display the result:
Set Management m Error while writing (incorrect value, parameter write-protected, invalid parameter numSystem
ber)
m Error while reading
m Command processing running
m Error code
Some commands for data set management require additional parameters, which are listed as follows:
m Z105.8– Source Data Set
Source data set for certain commands such as "Copy" or "Reload".
m Z105.9– Target Data Set
Target data set for certain commands such as "Create" or "Delete".
m Z105.6– Active Data Set Number
The number of the active data set is shown here. Writing to this parameter effects an
immediate change of data set.
m Z105.3– Message Text 
Array with 20 entries
Displays the number of the parameter for which an error occurred with the last data set
command. If an error occurs during command processing, the command does not interrupt the transfer procedure but instead continues the transfer procedure with the
next parameter.
m Z105.5– Data Set Identification Number
Unique ID number for the data set stored in Flash memory
m Z105.4– Data Set Name
The name of the active data set (string) can be freely assigned by the user.

3.5.2.9 Data Set Commands and Possible Error Messages
m Reset the Data Set Management System
This command results in a reset of the message list and the status word of the Data Set
Management System.
n Possible error messages:
None
m Write all parameters to Flash memory
This data set command saves all the parameters in the created data sets from RAM to
Flash.
m Load parameters from Flash
This command reads all the parameters from Flash into the RAM of the device. This command is only possible when the device is locked.
During the copying procedure, any changeover of the data sets is inhibited.
Possible error messages:
n Device is not inhibited
n Value less than minimum value
n Value greater than maximum value
n Parameter is read-only
n Due to operating state, parameter cannot be changed
n Parameter value is invalid
n Check yielded faulty checksum
m Delete parameters in Flash
This data set command deletes the parameters saved in Flash.
Possible error messages:
n Error writing to Flash
m Set standard values for all savable parameters
All savable parameters of the device are set to their standard values. This command is
only possible when the device is locked.
m Create Data Set <n>
When a device is delivered, initially only a single data set (Data Set 1) is activated. The
user cannot switch to other data sets, therefore. Only after the user has created a further
data set (2 to 7) using this command will the device allow switching to this data set. This
measure is intended to guarantee that the user cannot switch unintentionally to an as yet
unmodified data set. He is thus compelled to consciously enable a data set for the
changeover.
This data set command creates a data set which is selected with Z105.9– Target Data
Set. The parameter values for this data set (the data set parameter only) are set to their
standard values in the process.

The operation only takes place in the device RAM.
Possible error messages:
n Data set has already been created
n Incorrect data set number (not in range 1 to 7)
m Delete Data Set <n>
This data set command deactivates a data set. The data set specified by Z105.9– Target
Data Set may not be the immediately active data set. The deactivation has the effect of
preventing the device from switching to the specified data set any more. The parameters
of the deleted data set (the data set parameter only) are set to default values.
Possible error messages:
n Incorrect data set number (not in range 1 to 7, active data set)
m Copy Data Set <x> to Data Set <y> (from RAM to RAM)
This data set command copies in RAM the parameters from Data Set x (Z105.8– Source
Data Set) to the parameters of Data Set y (Z105.9– Target Data Set). The copying procedure takes a few milliseconds - for that reason the command is only permitted when the
device is inhibited.
Only source data sets that are already created may be specified. If a target data set that
has not yet been created is specified, it will be created automatically.
Possible error messages:
n Incorrect source data set number
n Incorrect target data set number
n Device is not inhibited
m Load Data Set <x> from Flash
This data set command loads all the parameters in Data Set x (Z105.8– Source Data Set)
from Flash memory to the device's working memory. The target data set corresponds to
the source data set. The data set must have been created. In Online mode (operation enabled), the data set must not be the immediately active data set. During the copying procedure, any changeover of the data sets is inhibited.
Possible error messages:
n Incorrect source data set number
n Device is not inhibited
n Value less than minimum value
n Value greater than maximum value
n Parameter is read-only
n Due to operating state, parameter cannot be changed
n Parameter value is invalid

m Set Standard Values for an Individual Data Set
This data set command resets all parameter of the target data set (the data set parameter
only) to the default values.
Possible error messages:
n Device is not inhibited
3.5.2.10 Changeover to Data Set 1 to 7
Changing data sets is possible both with the device inhibited and with the controller running.
Due to the mechanical inertia of the systems being controlled and the high sampling rate
of the drive, a changeover free of mechanical shocks can be assumed.
NOTE!
No consideration can be given to inconsistent set values and monitored values during
the changeover of data sets. During the changeover, the possibility cannot be ruled
out that, e.g., a monitored value in the new data set is smaller than the associated
instantaneous actual value of the previously active data set. In this case a monitoring
function which, e.g., initiates a pulse inhibit could respond.
The data set changeover is effected by writing to the Parameter Z105.6– Active Data Set
Number.
Before the changeover, a check is made to ensure that the data set has been created.

Brake management
3.5.3.1 Description of the Brake Management System
On drives with a motor holding brake, the brake can be operated manually or automatically depending on the state of the drive.
The triggering is effected by means of a selectable digital output. A digital input must be
selected to detect the brake state. The outputs and inputs are located on terminal X2. The
brake state can be monitored. When monitoring is active, an error message is transmitted
in the event of an error (brake could not be enabled/applied).
Adaptation to the differing reaction times of holding brakes is possible by means of configurable response times and delay times.
Manual Brake Triggering (Z134.1– Bit 0 = 0)
The brake can be applied and enabled independently of the state of the drive.(Z134.4–
Bit 0).
Automatic Brake Triggering (Z134.1– Bit 0 = 1)
In the Automatic mode, the brake is actuated depending on the state of the device controller (see ZDrive management– from page 281). In states 0 ("Not Ready to Switch On")
to 3 ("Switched On"), the brake is applied. The brake is enabled on the transition to State
4 ("Operation Enabled").
For commissioning purposes (Z134.4– Bit 1 = 1), the brake can also be applied and enabled manually in the Automatic mode (service mode).
Enabling the 
Brake
When the drive is started, power is applied to the motor in state transition 3  4
("Switched On"  "Operation Enabled") before the brake is enabled. This prevents a suspended axis from sagging. The requirement for this is at least a speed-controlled operating mode.
NOTE!
A suspended axis will NOT be prevented from sagging in the following cases:
m The drive is working in one of the modes "Find Notch Position", "Autotuning", "Current Control", "Current Setting" or "Voltage Setting".
m The drive is being operated without encoders.

Three different modes can be selected for enabling the brake, see also Torque Characteristics ZFig. 92– on page 327.
m Without holding torque preset
The torque for holding the load is built up after the brake is enabled. As a result of the
control deviation required for this, there is negligible sagging of the load.
If the outer load torque for a suspended axis is known, a compensating holding torque
can be applied before the brake is enabled:
m With holding torque preset; brake enabled when drive torque = holding torque
The torque for holding the load is built up before the brake is enabled. When the torque
is reached, the "Enable Brake" command is sent. If the holding torque corresponds exactly to the load torque, the drive does not sag. Any difference between the load torque
and the holding torque set in the parameters results in a negligible movement and is corrected. If the holding torque set in the parameters cannot be achieved, the brake will not
be enabled and the drive will go into the "Error" state.
m With holding torque preset: brake enabled when waiting time elapsed
The torque for holding the load is built up before the brake is enabled. Regardless of
whether the torque has been reached, the "Enable Brake" command is executed after a
preset time Z134.10–. If the holding torque corresponds exactly to the load torque, the
drive does not sag. Any difference between the load torque and the holding torque set in
the parameters results in a negligible sag and is corrected.

The following recommendation applies for setting the delay to the start of the movement,

1
If the state monitoring is switched off (Z134.1– Bit 1 = 0):
TB > T1)SignalCom + T2)mech
2
If the state monitoring is switched on (Z134.1– Bit 1 = 1) and the response signal is
reporting the state of the current through the brake:
TB > Tmech – T3)SignalFB
3
If the state monitoring is switched on (Z134.1– Bit 1 = 1) and the response signal is
reporting the mechanical state of the brake:
TB = 0
Applying the

1)
Processing time for the command in the controller, max. 2 ms
2)
Operating time of holding brakes depends on type, approx. 75-350 ms
3)
Duration of current buildup in brake coil (depends on type, approx. 30 ms) + processing time for response in
controller: max. approx. 32 ms. 
The following must apply for a correct error reaction:
Z134.7– timeout check-back signal > TSignalCom + TSignalFB
When applying the brake, account is taken of whether the drive is still under torque or
whether the pulses are inhibited.
Pulses are enabled (drive is under torque)
If the drive is being actively braked (response to QUICK STOP/SHUT-DOWN/INHIBIT/drive error) and if the torque is to be reduced after the end of the braking procedure
(pulse inhibit), the brake is applied when a presettable speed threshold is reached. The
subsequent pulse inhibit can also be delayed if this is required to compensate for a mechanical dead time.
If the activated state monitoring detects that the brake could not be applied, the drive remains under torque in the "Quick Stop active/drive shut-down active/inhibit operation active" state in order to prevent sagging of a suspended axis. Error messages 1102/1103
indicate this state. The user can still move the drive into a torque-free position and then
shut off the drive torque (pulse inhibit or inhibit voltage). The conditions and events required for the transition to the "Enabled" state can be found in the description of the state
transitions in the device control system (Zpage 282– ff).
NOTE!
The following must be observed to prevent a suspended axis from sagging after an
active braking procedure at the end of which the brake could not be applied:
The responses to Errors 1102/1103 must be set to "No response" and Errors
1102/1103 may only be reset after the enable is repeated, otherwise the drive will be
without torque before it can be enabled.
In the "Error response active" state, this check is not carried out, i.e. even with the state
monitoring activated and the brake not applied, the transition to the "Error" state takes
place. The drive will consequently be without torque.

Pulses are inhibited (drive is without torque)
If the drive is suddenly without torque due to a pulse inhibit (HW input or response to
QUICK STOP/SHUT-DOWN/INHIBIT/drive error), the brake could be applied immediately or when the speed threshold (see above) is reached. With a suspended load, it is recommended that the brake be allowed to be applied immediately in this case (Z134.3–
Bit 2 = 0) as the drive could be accelerated by the externally acting torque, with the result
that the speed threshold is not reached and the brake is not applied.

If there is a "suspended load" and at least a speed-controlled operating mode, the torque required to hold the
load is built up AFTER the brake is enabled by the control deviation
2)
The torque required to hold a load is built up BEFORE the brake is enabled. If the parameters for the holding
torque are correctly set, the load therefore sags significantly less after the brake is enabled than in 1).
Command
Command to the motor holding brake
In the triggering mode (Z134.1– "Automatic"), 134.4 Bit 0 of the device control state machine is activated. However, if the brake is to be triggered in the "Automatic" mode for service purposes by writing directly to 134.4 Bit 0, 134.4 Bit 1 must be set. After the service
mode is switched off, the brake remains in its current state, i.e., the original state before
the service mode was activated is not re-established.
If the motor holding brake is to be actuated manually (Z134.1– "Manual"), the command
must be transmitted to the brake directly via 134.4.

Torque limit
Torque limit for torque-controlled enabling of the motor holding brake in the Automatic
mode (Z134.1– Bit 0 = 1). This torque is built up before the brake is enabled if the appropriate mode is selected (Z134.3– Bit 0 = 1).
See also ZEnabling the Brake– from page 325
134.6
Speed limit
Threshold value for speed-dependent engagement of the motor holding brake in the Automatic mode (Z134.1– Bit 0 = 1). The brake is applied in the following cases as soon as
the magnitude of the instantaneous speed has fallen below the threshold value:
m Drive is actively braking (hold on ramp)
m Drive is without torque (pulses are inhibited, Z134.3– Bit 2 must be 1)
134.7
Timeout check-back signal
Timeout for evaluating the state response signal. If the expected brake state (enabled/engaged) is not detected within the timeout period, an error reaction is initiated.
134.8
Pulse inhibit delay
Delay to allow for the brake engagement time and, where necessary, the dead time due
to a relay in the Automatic mode (Z134.1– Bit 0 = 1). After the brake is applied during an
active braking procedure (e.g. Quick Stop on ramp) the pulses are inhibited at the earliest
after the time set in 134.8 has elapsed. Hence it can be ensured that the drive will only
be without torque once the holding brake has built up the full mechanical braking force:
m The evaluation of the brake state is switched off (Z134.1– Bit 4 = 0):
The pulse inhibit occurs at the earliest after the time set in 134.8 has elapsed following
the issue of the engage command by the drive manager.
m The evaluation of the brake state is switched on (Z134.1– Bit 4 = 1):
The drive is without torque at the earliest after the time set in 134.8 has elapsed following reception of the "Brake is engaged" confirmation.
See also ZApplying the brake– from page 328
134.9
Start of motion delay
Delay to allow for the brake enable time and, where necessary, the dead time due to a
relay in the Automatic mode (Z134.1– Bit 0 = 1). After the brake is enabled an acceleration takes place at the earliest after the "Start of motion Delay" time set in Automatic mode
(Z134.1– Bit 0 = 1). Hence it can be ensured that the drive is not working against the
holding brake which is possibly not yet fully enabled:

134.10
Opening delay
Delay between the start of the buildup of holding torque and the "Enable brake" command
in Automatic mode (Z134.1– Bit 0 = 1). 
134.10 is only evaluated if a holding torque is to be built up before the brake is enabled
and the brake is to be enabled after a presettable time (Z134.3– Bit 1...0 = 3). The "Enable brake" command is issued [134.10] ms after the start of the buildup of the holding
torque.

Error Management
The error messages and warnings of the drive are displayed in a central error memory
(Z100.3– Error Information). This parameter is an array with 20 elements. Both error
messages and warnings are displayed in this array parameter.
Certain additional information is displayed at any error as e.g. the timestamp when the
error was messaged and reset.
The drive response to an error is configurable. Though the response to each error can be
set separately (see parameter Z100.4–). The following responses are possible:
Error response
Description
No error message
The error will not be messaged.
No error response
The error is messaged but there is no response of the drive
(e.g. pulse block).

The drive is stopped at the quick stop ramp. Afterwards the
pulses are locked and the drive goes in the failure state.
Stop (RFG-Ramp-down The drive is stopped at ramp down of the ramp function gentime)
erator (Parameter 110.x). Afterwards the pulses are locked
and the drive goes in the failure state.
Return motion
The drive positions to an adjustable position. Afterwards the
pulses are locked and the drive goes in the failure state.
Controlled stop
The drive is braked at the ramp for the controlled stop. Afterwards the pulses are locked and the drive goes in the failure
state.
SS1 stop
The drive is braked at the ramp for the SS1 stop. Afterwards
the pulses are locked and the drive goes in the failure state.
According to the error code not all error responses are possible. For example the pulses
are blocked at certain errors at once. Another response is not adjustable for such errors.

Signal Bus
The signal bus is a connection between the supply unit and the connected axes in the DC
link network. The ready for use signal of the supply is signalized to the connected axes
via this connection.

The signals are active HIGH. A disjunction is implemented via the cabling. This means
the signal is set to HIGH as soon as at least one connected device has set the signal to
HIGH.
The signals in the devices are monitored at 1 ms intervals.
3.5.5.2 Supply Ready for use
This signal is generated by external supplies. The connected axes evaluate this signal.
The signal indicates that the supply unit is in the ready for use state and the DC link is
supplied. In the event of supply errors (e.g. power supply failure), the output of the ready
fur use signal is stopped. If the signal is not available, an error is generated at the connected axes units.
3.5.5.3 Chopper Resistor On
This signal activates the chopper resistors of several supplying devices simultaneously.
Both mains rectifier unit and mono units provide a chopper resistor connection and an
own monitoring of the DC link voltage. If the DC link voltage exceeds a fixed threshold,
the chopper resistor is switched on.
The axis units monitor also the DC link voltage and can be configured to generate the
Chopper Resistor On signal. If this signal is set, the chopper resistor is switched on at
the mains rectifier unit.

Set Value Manager
The set value manager manages the initial values of set value generators such as, for
example, ramp function generators or positioning and operates the set value interface to
position and speed controllers. Furthermore, using Z111.6– Interpolation Mode it is possible to select between interpolating and extrapolated characteristics of speed and position.
The display parameters Z111.2– to Z111.5– are updated in the set value manager cycle.
The cycle depends on the active operating mode (Z109.2–).
For the operating modes which work in the so-named RT1 Task, the cycle time is always
1 ms. An active RT1 operating mode can be recognized by Z111.1– Status Bit 4 = 1. RT1
operating modes are all position and speed controlled modes for which the speed profile
is produced internally to the controller. Examples of RT1 operating modes are target position setting (Z109.2– = 1) or speed control (Z109.2– = -3).
The operating modes which work in the Fieldbus Task (e.g. cyclic position set value specification), the cycle time always corresponds to the fieldbus cycle time (Z131.18–). An active Fieldbus Task operating mode can be recognized by Z111.1– Status Bit 5 = 1.

Interpolation mode
Using this parameter, the mode for the interpolation at the set value manager to controller
interface can be set.
The interpolator receives new set value data in the set value manager cycle, which it interpolates or extrapolates according to the mode. The set value data consist of acceleration, speed and position. An interpolating or extrapolating behavior can be set separately
for speed and position by means of the interpolation mode.
Any change in the mode only takes effect after a controller inhibit.

Remarks:
m Mode 0:
As a result of the linear extrapolation of speed and position, feedforward of the two values is achieved. The dead time between the input set value to the set value manager
and the set value to the controller input is consequently reduced. The procedure is only

recommended for very small changes in acceleration, since the extrapolation is no longer exact for each change in acceleration. This can lead to overshooting of the intended position and intended speed at the controller input.
m Mode 1:
As a result of the linear interpolation of speed and position, Mode 1 avoids the negative
effect described under Mode 0 for changes in acceleration. A dead time is generated
about one set value manager cycle for the speed and about two cycles for the position
instead.
m Mode 2:
This mode is a mixture of Modes 0 and 1. The position is linear extrapolated, the speed
linear interpolated. As a result of the interpolation of the speed, overshoots in the speed
set value or speed feedforward value are avoided. At the same time, due to the linear
extrapolation of the position the position controller receives a deadtime-optimized position set value.
m Mode 3:
The mode 3 carries out a linear interpolation speed and a quadratic interpolation of the
position. As in mode 1 the position is delayed by two set value manager cycles and the
speed by one cycle.
m Mode 4:
Mode 4 carries out a quadratic interpolation speed and a cubic interpolation of the position. Here the position and the speed is delayed by two set value manager cycles.
NOTE!
If several axes are to be operated collectively, the same interpolation mode should
be set on each axis.

External speed feedforward
This parameter permits the presetting of an external speed feedforward by a fieldbus.
This parameter takes effect in operating mode Position control with synchronous set value specification (Z109.1– = -4) only. The function is activated by Z18.9– Controller options bit 3 = 1.
NOTE!
The parameter Z111.6– Interpolation mode must be set to mode 0 (extrapolation) at
the external feedforward. The fieldbus cycle time (Z131.18–) must correspond to the
controller cycle (Z1.8–) in order to achieve an optimum result.

Ramp function generator
The ramp function generator is used to generate rising or falling ramps in the Speed Preset 1 (Z109.1– = 2) and Speed Control (Z109.1– = -3) speed-controlled operating
modes. Additionally, it is used for controlling braking procedures (Quick Stop, Drive Shutdown, Inhibit Drive).
The ramp function generator has an input with separately adjustable ramp-up and rampdown times. Furthermore the ramp-down time for the Quick Stop function is separately
adjustable.
The input and output values for the ramp function generator are relative quantities
(±100 %) and are referred to the Maximum drive speed parameter (Z110.13–).
The ramp slope for the acceleration and braking procedures is defined by the ramp-up
and ramp-down times. The times correspond to a 100 % change in the set value.
For additional rounding of the ramp-up or ramp-down ramps, a PT1 element (smoothing)
with adjustable time constant is connected after the ramp function generator.
The ramp function generator provides the following control options via the control word
(Z108.1–):
m Inhibit ramp generator (set output permanently to 0, ramp-down at the current limit)
m Stop ramp generator (freeze output value)
m Inhibit ramp generator set value (set input internally to 0, ramp-down on the ramp-down
ramp)
The following options can additionally be selected via Ramp Generator Mode Z110.2–:
m Selection between a 16-bit parameter (Z110.5–) or a 32-bit parameter (Z110.4–) as
input value for the ramp function generator.
m Blocking of positive or negative set values.
m Reversal of set value sign. The internal processing sequence is inhibit before sign reversal.
m Switch-off of speed set value synchronization when activating the ramp function generator.
m Adjustment of ramp shape:
n Trapezoidal speed profile; stepped acceleration. 
There is a possibility of smoothing the speed by means of a PT1 element.
n S-Curve with quadratic speed profile; trapezoidal acceleration.
m Speed profile in zero-crossing at change of direction with or without rounding-off.
m The set quick stop time Z110.8– applies to
n change of set value from 100% to 0%
n change of set value from actual set value at ramp function generator output Z110.3–
to 0%. This causes a constant braking time from all speeds at ramp function generator output.
m The set SS1 stop time Z110.21– applies to
n change of set value from effective speed to 0%. This causes a constant braking time
from all speeds.
n change of set value from 100% to 0% (braking deceleration independent of the instantaneous speed).

For correct functioning of the braking procedures on the Quick Stop or Ramp-down
ramps, the speed controller must be adequately configured.
Trapezoidal Profile
The ramp-up and ramp-down times refer to a change in the input set value of +100% or
-100%.
The resulting times for other set value changes are calculated as follows:
TResRamp-up = TRamp-up * Set Value change / 100 %
TResRamp-down = TRamp-down * Set Value change / 100 %
TRamp up= Ramp-up time Z110.6–

S-Curve Profile
Acceleration and braking are introduced more smoothly with the S-Curve profile.
The time to reach maximum acceleration or deceleration is set using the S-Curve time.
The maximum value of the accelerations is determined by the ramp-up time or the rampdown time. The S-Curve time can be set separately for the ramp-up and the ramp-down.
The ramp-up or ramp-down time resulting from a change to the input set value of 100 %
can be found from
TRamp-upTotalTime = TRamp-upTime + TSCRamp-upTime

The equations apply only to a set value change from standstill (Set Value = 0%; Acceleration = 0).
For set value changes less than 100%, two cases for determining the resulting ramp-up
and ramp-down times must be distinguished:
n the maximum acceleration or deceleration is achieved
n the maximum acceleration or deceleration is not achieved
In the following, the calculation of the resulting ramp-up time for the two cases is explained by means of examples for the ramp-up.
The calculation of a resulting ramp-down time would be performed in the same way using
the parameters Z110.7– Ramp-down Time and Z110.10– S-Curve Ramp-down Time.
The times are set identically for the examples:
Z110.6– Ramp-up time = 800 ms = TRamp-up
Z110.9– S-S-Curve ramp-up time = 200 ms = TScurve
Example 1:
Set Value changed by +50 %
Total set value change dVtotal = 50%
Calculate proportion of "S-Curve phase" in the acceleration process:
dVScurve = TScurve / TRamp-up * 100 % = 200 ms / 800 ms * 100 % = 25 %
dVScurve < dVtotal
maximum acceleration is achieved.
Calculate proportion of phase at maximum acceleration:
dVamax = dVtotal - dVScurve = 50 % - 25 % = 25 %
Duration of phase at maximum acceleration:
tamax = dVamax / 100 %* TRamp-up = 25 % / 100 % * 800 ms = 200 ms
Now determine the resulting ramp-up time:
ttotal = 2 * TScurve + tamax = 2 * 200 ms + 200 ms = 600 ms
Example 2:
Set Value changed by +12.5 %
Total set value change dVtotal = 12.5%
Calculate proportion of "S-Curve phase" in the acceleration process:
dVScurve = TScurve / TRamp-up * 100 % = 200 ms / 800 ms * 100 % = 25 %
dVScurve > dVtotal
maximum acceleration is not achieved.
only "S-Curve phase" present
Now determine the resulting ramp-up time:

3.6.1.1 Optional interpolation of the ramp function generator input set value
A cyclical and synchronous transferred speed set value which is mapped to the input set
value (Z110.4– or Z110.5–), can be interpolated optionally to the ramp function generator (RFG) cycle (= 1 ms). The speed profile is calculated by the controller and is transferred in the adjusted set value cycle. The interpolation is switched on by setting bit 11 in
Z110.2– Mode. The ramp function generator is usually switched off at active interpolation.
The controller interpolates from set value cycle to the ramp function generator cycle
(1 ms). For this the set value cycle in parameter Z145.11– must be set and the interpolation must be activated. Both must take place before enabling the operation mode speed
control or speed setting 1. A change at active ramp function generator is invalid!
The ramp function generator interpolates from a set value cycle of 2 ms.
Example 1:
Example 2:
Fieldbus cycle = 1 ms, set value cycle = 6 ms und ramp function generator cycle = 1 ms

A new calculated set value is transferred only in every sixth fieldbus cycle

Z131.18– Fieldbus cycle time = 1 ms

Z145.11– Virt. master set value cycle time = Interpolation interval = 6 ms

6 ms / 1 ms - 1 = 5

Interpolator generates 5 interpolated set values in the ramp function 
generator.
Fieldbus cycle = set value cycle = 2 ms and ramp function generator cycle = 1 ms

A new set value is transferred in each fieldbus cycle.

Z131.18– Fieldbus cycle time = 2 ms

Z145.11– Virt. master set value cycle time = Interpolation interval = 2 ms

2 ms / 1 ms - 1 = 1

Interpolator generates 1 interpolated set value in the ramp function generator.
Always the sum of main and additional set value will be interpolated, i.e. the value of
Z110.17– Input 32 bit additive is also effective at interpolation. Every change of the total
set value is immediately effective and interrupts a running interpolation if necessary.
The interpolator is implemented before the ramp function generator controller and the
ramp generator. Thus the functions of the ramp function generator remain also at active
interpolator, as e. g. limitation and polarity reversal of the input value, directional block,
ramp function generator block, ramp function generator stop, quick stop function and
ramp generator.

This interpolator must not be confused with the interpolator of the ramp function generator
cycle to controller cycle. This interpolator is specified in chapter ZSet Value Manager–
from page 344.
Interpolator active and ramp generator switched off
The ramp generator can be switched off either via Z110.2– Mode bit 10 (transparency
mode) or via setting ramp times to zero (Z110.6– and Z110.7–). The ramp function generator operates in both cases in the "transparency mode" (output = input), i. e. the cyclical
input set values are immediately effective at ramp output.
m Switch off via ramp times (= 0 s)
This means a stop at current limit, because the ramp-down time can be used also for
quick stop or error response ("stop at deceleration ramp"). If this is not desired, the stop
at deceleration ramp and the quick stop time in Z110.8– must be set or the transparency mode via bit 10 must be used.
m Switch off via Mode bit 10 of parameter Z110.2– 
The ramp-up and ramp-down times can be set here as required. In case of a stop at
the deceleration ramp, it will be broken at the deceleration ramp.
The bits 8 (Ramp-up is active) and bit 9 (Ramp-down is active) in Z110.1– are not
changed.
Interpolator and ramp generator active
The ramp generator is switched on, if ramp times greater than 0 s are parameterized and
if no transparency mode via bit 10 is activated. The set times limit the maximum acceleration or the deceleration of the cyclic input set values. If the S-Curve profile is activated,
the acceleration change (jerk) is limitied via the S-Curve times.
If the limitation is effective, the speed profile of the cyclical speed set values will be
changed.
NOTE!
m The input set value will be delayed by one set value cycle when using the interpolation.
m The following ramp function generator smoothing (Z110.11–) must be set to 0 ms,
if it should not effect.
m At set value failure the last speed set value remains valid. An extrapolation does
not take place using the last acceleration value.
m If the control functions of the ramp function generator (block, stop, zero, ...) will be
used or after a stop triggered by hardware limit switch, the input set value must be
corrected by the control before the function is canceled.

Set Value Generators
m Bit 6:
The speed synchronization is activated as standard by Z110.2– Mode Bit 6 = 0.
It acts when the ramp function generator is activated, e.g., by changing over or activating operating mode -3 (speed control), so that no jump in speed occurs.
When it is activated, the ramp function generator initializes its output to the current actual speed and controls the output to its input value according to the preset ramp.
If Bit 6 is set, the ramp generator output will not be synchronized to the current actual
speed when the ramp generator is activated. 
m Bit 7:
If the bit is set, the ramp function generator output Z110.3– decelerates to 0% in the
quick stop time Z110.8–, which was set.
If the trapezoidal speed profile (Z110.2– Mode bit 4 = 0) is set, the set quick stop time
is only valid for the non smoothed curve. The braking time is delayed with smoothing
(Z110.11– Smoothing > 0) depending on the value of the set smoothing
If the S-Curve profile (Z110.2– Mode bit 4 = 1) is set, it is decelerated with trapezoidal
speed profile at quick stop. A set smoothing is not effected. 
m Bit 8:
If bit 8 is set, a stop at the deceleration ramp is set at active hardware limit switch and
at active limit switch monitoring (Z121.1– bit 1 = 1). This requires that either the error
message is deactivated via Z110.2– bit 9 = 1 or the error reaction „no reaction“ is set.
The following description is true for the activated error message (Z110.2– bit 9 = 0.
At crossing of a hardware limit switch the error code 906 „Negative hardware limit
switch active“ or 907 „Positive hardware limit switch active“ is set. The following behavior of the drive corresponds to the preset error reaction for the respective error code.
The default value for this error is „no reaction“.
n „No reaction“ and Bit 8 = 0:
Only the respective error is set. New set values from the ramp function generator
input are accepted furthermore. The correspondent reaction must be carried
through the controller. The error can be reset not before a velocity in the „free“ direction is existent at the ramp function generator output Z110.3–. If the hardware
limit switch is still active and it will be stopped again or driven in the blocked direction
the error message will be sent again.
n „No reaction“ and Bit 8 = 1: 
Among the error message a stop is set additionally. The deceleration occurs with the
delay set in Z110.7– ramp-down time. Set values over the ramp function generator
input are ignored. After the termination of the stop (velocity set value at Z110.3– output of the ramp function generator = 0) the errors of the limit switch may be reset.
After this it may be driven in the „free“ direction. If the hardware limit switch is still
active and it will be driven in the blocked direction again the error message will be
sent again. The blocked direction is displayed in Z110.1– Status Bits 18 and 19. 

m Bit 9:
With bit 9 the error message and error reaction at run over hardware limit switch can
be switched off. This setting is true for both hardware limit switches.
If a stop at the deceleration ramp should be set at reaching the hardware limit switch
in spite of switched off error message, bit 8 in Z110.2– must be set. 
m Bit 10:
The ramp function generator can be switched off without changing the ramp-up and
ramp-down time with this bit. Details see ZOptional interpolation of the ramp function
generator input set value– from page 353.
m Bit 11:
The bit activates the input set value interpolator for cyclical speed set values. The function of the ramp function generator input set value is described in ZOptional
interpolation of the ramp function generator input set value– from page 353.
m Bit 12:
With this bit the rounding-off of the speed in zero-crossing at change of direction can
be switched on. Rounding-off in zero-crossing means acceleration = 0 at speed = 0.
Thus the period will be extended up to the reaching of the new input set point. The advantage of this setting is the reduced loading of computing time if the S-Curve profile
is activated and the application needs a flying change of direction. This mode has no
advantage for the trapezoidal profile and should be switched off.

A PT1 element is implemented to achieve rounding of the ramp corners. The time constant of the PT1 element can be adjusted using this parameter.
The smoothing is only effective if a trapezoidal profile is set for the ramp shape.

If Maximum drive speed is greater than Z107.26– Max speed mech., error 212 is set
at drive enabling in the operating modes 2 and -3. Maximum drive speed must set so
that the maximum speed mechanical of the motor cannot be exceeded. If the error is

Set Value Generator
Function
The set value generator generates a constant set value for each of 4 time zones. The set
value and the time for each zone are adjustable.
The set value generator can write to all cyclic writable parameters. With the time, the issue time for the respective set value is set.
If the set value generator switches over the current positioning set of the axis
(132.4 = 118.6), the time specifies the length of time spent in the target position.
Furthermore it is possible to determine whether the set value generator will start again
with the first time zone after the last time zone has elapsed (looped operation), or whether
only one cycle is run through and the last set value is preserved.
Thus the following speed set value sequence can be produced, for example:
rev
min
Set value 1
Set value 1
Set value 2
Time 1
Time 2
Time 3
Time 4
t
Set value 3

Figure 103:
Speed set value sequence for set value generator
The set value generator has a cycle time of 1 ms. It can always be switched on or only
when the drive is enabled. Starting always takes place with the first set value in the preset
profile.

Error reaction controlled stop
Another error reaction is the controlled stop. This is required if the motor must be stopped
quickly, but the error reactions "Stop at current limit", "RFG Quickstop ramp" and "RFG
Ramp-down" are not possible, e.g. because of an encoder error.
There are two versions of the controlled stop, braking in I/f operation and braking in U/f
operation, which can be selected in parameter Z18.9– bit 6.
In I/f operation a constant current is preset by parameter Z133.22– and then the ramp of
the RFG is started at the last effective speed set value. Subsequently the frequency is
reduced linearly to frequency 0. If the speed set value is not available the last speed actual value is used as start value.
At braking in U/f operation the current set values are controlled to 0 A at the frequency of
the last effective speed set value for a short time. The voltages adjust themself according
to the EMF of the motor. Subsequently the voltages are reduced linearly to standstill.
A soft torque reduction (see Z108.19–) is possible for both error reactions. At braking in
U/f operation the voltage at speed 0 is reduced only to zero voltage (Z166.5–). Subsequently the residual voltage is reduced linearly to the time for torque reduction.
NOTE!
If the error reaction controlled stop is selected for an encoder error, other errors must
set to this error reaction, which can occur subsequently to a faulty encoder evaluation. This includes the following errors 203 and 204 (overspeed), 201 (speed control
deviation) and 211 (field angle monitoring).

Error Reaction Return Motion
In addition to the error reactions „Stop“ and „Pulse inhibit“ the reaction „Return motion“ is
settable for some errors. It concerns an easy positioning with trapezoid profile, whose target position can be set absolutely or relatively to the current position.
For many errors, e.g. error no. 1016 „Mains failure (Mono unit)“ in addition to the standard
error reaction as „Pulse inhibit“ and „Stop“ also the error reaction „Return motion“ is settable. At initiation of an error with the „Return motion“ reaction the drive goes to a therefor
parameterized target position. The speed profile during the positioning to the return motion target is preset by a parameterized trapezoid (maximum speed, maximum acceleration). The maximum speed must not be greater than the maximum speed of the drive.
The return motion target can be preset absolute or relatively in relation to the Z106.12–
Position actual value. If the return motion target is not reached, then this will be registered
in Z148.2– Status and the corresponding error message no. 2703 is transmitted. For this
purpose the position error of return motion is monitored. The return motion target is considered as not reached, if a position error is recognized according to the limit in Z148.6–
Position Error Limit and Z148.7– Position Error Time.
The return motion positioning is not an operating mode of its own. During positioning to
the return motion target the drive remains in the „error reaction active“ status (see ZState
Machine of the Device Controller– on page 285 in chapter Drive management).
NOTE!
If the error reaction „Return motion“ is set for the error mains failure, then also the
motor-driven operation at mains failure must be set (Z130.10– Supply mode
bit 1 = 1).

Set Value Generators
3.6.5
Cam generator
A cam generator is integrated in the controller firmware. The cam generator reads a value
from a configured table (cam). The cam generator writes this value to a target parameter.
The cams are generated with the program ProCam and are loaded into the device with
ProDrive.
The cam generator supports the modes for table request
1
Time control via the table index
2
Time control with virtual master axis
3
Parameter controlled processing
The index of the cam is recalculated by the cam generator in the fieldbus task cycle. The
operation of the fieldbus task allows the use of "Synchronous set value setting". Here, the
set values are available in the fieldbus cycle. It is interpolated and extrapolated between
the single set values, in order to operate the closed loops, which are running quicker.
NOTE!
According to application, the homing of the drive must be executed, before the cam
generator is started.
3.6.5.1 Time control via the table index
At time controlled processing, the table index is increased by one with each cycle.
3.6.5.2 Time control with virtual master axis
The index from the position of the virtual master axis Z159.10– results, if it is controlled
via a virtual master axis. The speed is set via Z159.9–. Interpolation between the single
cam supporting points can be processed in 256 steps. The following cam interpolation table with the following supporting point count is generated:
Count_Interpolation points = 256  Count_Supporting points
The position of the virtual master axis is set, referring to the interpolation table. This
means, that the virtual master axis is positioned exactly on the supporting point with table
index Z159.4– = 2 (whereat the table index starts with 0), if the virtual master axis positioning is specified with Z159.10– = 512. The virtual master axis speed is set as a positioning change per cycle within the interpolation table. Therefore, the progress per cycle
on the interpolation table is exact one supporting point, if the virtual master axis speed is
256.
Processing time of the cam using the virtual master axis is calculated by:
Count_Supporting points  256
Processing time = --------------------------------------------------------------------------  Cycle time of field bus task
Virtual master axis speed

If a negative virtual master axis speed Z159.9– is selected, the cam is processed reversely.
Example for the calculation time of processing with a virtual master axis:
Count supporting points Z159.5– = 512
Virtual master axis speed Z159.9– = 216
Fieldbus task cycle time Z1.10– = 1 ms
512  256
Processing time = ----------------------  1 ms = 0.60 s
216
In order to obtain the required speed, in order to process the cam in 0.4 sec,
the following is required:
Cycle time of field bus task
Virtual master axis speed = Count_Supporting points  256  -----------------------------------------------------------------Processing time
1 ms
Virtual master axis speed = 512  256  ----------------- = 328
400 ms
3.6.5.3 Parameter-controlled processing
With parameter-controlled processing, the table index is specified by an input parameter
and is adjusted by an accordant parameterization.
Index calculation is made as follows:
m Input parameters - type "Float":
Index = Parameter value – Base value (P159.14)
m Input parameters - type "Integer":
n Processing is executed once, only (Z159.2– bit 5 = 0):
Index =  Parameter value – Base value (P159.14)  >> Shift factor (P159.15)
n Processing is executed cyclical (Z159.2– bit 5 = 0):
Mask = 0xFFFFFFFF >>  32 –  log 2 (Count_Supporting points  
Index =   Parameter value – Base value (P159.14)  >> Shift factor  & Mask
In order to process the AND operation in bit mode, the supporting point count
must comply with a power of 2 (for example 256 or 512).

Cyclical processing
1 Time controlled processing modes
If cyclical processing is selected in parameter Z159.2–, the cam generator jumps back
to the first table index after reaching the maximum table index Z159.4–. The cam generator then restarts processing. For more information, referring to the cyclical curve offset at a table index jump see chapter ZCyclical curve offset– on page 378.
2 Parameter-controlled processing mode
If the input parameters are float parameters, then the selection of the cyclical processing does not effectuate the behavior of float parameters as described in chapter
ZParameter-controlled processing– on page 376.
Additionally to the base value Z159.14– and to the shift factor Z159.15– at the input
parameters of an integer data type, a mask is generated to specify the index. This acts
on the input parameters. This mask operates after subtraction of the base value and
after shift operation. Referring to mask operation only those bits are used to specify the
index, which are required to activate the curve index.
Example:
Initial situation:
Value input parameter = 0x0075AB39 
Base value Z159.14– = 0xA000 
Shift factor Z159.15– = 7 
Count supporting points Z159.5– = 512
The following index results after subtraction of base value and after shift operation:
Index =  0x0075AB39 – 0xA000  >> 7 = 0xEA16
Having 512 supporting points applies to 512 = 29. Therefore, 9 bits are required to respond to the 512 supporting points of the cam. This mask, which contains 9 bits is generated by the controller. If there were 256 supporting points, then in conclusion the
mask will have 8 bits.
Example:
Index = 0xEA16 & 0x1FF = 0x16 = 22
Index 22 is the active table index.
If the cyclical processing is not selected, the active table index is the index 0xEA16 =
59926. This index is greater than the maximum index of (count supporting points - 1)
= 511. The active table index is limited to a maximum index of 511 at non-cyclical processing.

Cyclical curve offset
A curve offset is added to the output value of the cam. This offset is reset to 0 at the start
of processing (transmission from active to run). Each complete cam cycle increases the
curve offset by the cyclical curve offset in parameter Z159.6–.
This results in the following behavior:
1. Cam cycle: Output = Original curve
2. Cam cycle: Output = Original curve + 1 * cyclical offset
3. Cam cycle: Output = Original curve + 2 * cyclical offset
and so on.
If an offset cam is used (inequality of starting and end point), this offset is imported in a
cam file by ProCam and is transmitted to the controller during download. If the generation
of the cyclical offset is selected in the settings of the cam generator Z159.2–, then the
cam offset is loaded in parameter Z159.6– at state transition of the cam generator from
init to active.
m Time control with virtual master axis
Beginning with the greatest table index, the cam can be processed in processing mode
"Time control with virtual master axis" (reverse processing, if Z159.9– is negative).
Now, the cyclical curve offset is subtracted from the total curve offset after processing
is started.
m Parameter-controlled processing mode
The cyclical curve offset Z159.6– is added to the total curve offset, if the table index
overflows. This means, that a jump is made from a great table index to a small table
index. The cam generator recognizes this as an index overflow. The total curve offset
is increased by the cyclical curve offset. If there is a jump from a small table index to a
great table index, then the total curve offset is reduced by the cyclical curve offset.
Example:
Count supporting points = 32
Action:
Jump from table index 25 to table index 7
Consequence: 
The jump is detected as a positive overflow. This leads to an 
increase of the total curve offset around the cyclical curve offset.
NOTE!
The jump of index 25 to index 7 is interpreted as a jump above table index 31 and not
as a jump within the cam of table index 25 above index 16 and after index 7. This is
the case, because the jump width is greater than or equal to half the count of the supporting points. In this example the jump width (25 - 7) = 18 table indices is half of the
count of the supporting points (32 / 2) = 16 indices.

Set Value Generators
Relative mode
m Relative mode
If the relative mode is active, the value of the reference parameter is frozen, after the
cam generator is started. This frozen value is added to the output of the cam generator
output. This has no effects, if the reference parameter changes during the cam processing at an active cam generator. At the activation of the cam generator, the reference parameter value remains, until the cam generator freezes the new actual value
of the reference parameter at the next transmission from the state "active" into "run".
m No relative mode
If the relative mode is not active, the actual parameter value, which is selected in
Z159.7–, is added to the output of the cam generator. The starting of the cam generator does not freeze the parameter value.
Automatic offset
If the setting AutoOffset is made in parameter Z159.2–, the value of the input parameter
is frozen in the parameter-controlled processing mode, after the cam generator is started
and is subtracted from the input parameters during the processing period. It is ensured,
that the cam is processed with the first index by starting at the beginning.
Interpolation
If processing is parameter-controlled and if there is a time control with a virtual master
axis, then interpolation can be executed between the table entries. It is possible to select
between a linear and a square interpolation. These settings are made in Z159.2–.
Interpolation is not possible in mode "Time control" via the table index.
Interpolation can be executed in 256 steps between two supporting points.
m Time control with a virtual master axis
Interpolation between the single table entries is executed at time control via the virtual
master axis with the actual position of the virtual master axis Z159.10–. The table indices, between which the virtual master axis is positioned, are defined from the virtual
master and are interpolated between both of these table entries, accordingly.
m Parameter-controlled processing
n Input parameters "float"
At an active interpolation, the integer components of the input parameters define the
valid table index. The decimal position components define the interpolation point between the valid and the next table entry.
Example:
Count supporting points Z159.5– = 128
Base value Z159.14– = 0
Input parameter value = 29.8

At an active interpolation is interpolated between the table index 29 and 30. It
can be interpolated in 256 steps between these points. The interpolation point
is defined as follows:
Interpolation point = Decimal position component  256 = 0.8  256 = 204
n The input parameters are an integer data type
The lost information (due to shift operation) is used for interpolation with integer data
types.

After subtraction of base value, the index is 0x750B39.

The value of the 7 lost bits (due to shift operation) is 57.
The interpolation point is calculated as follows:
256 Interpolation point = Interpolation component  ----------------= 114

Interpolation must be operated in 256 intermediate steps. If the shift factor
Z159.15– is to be greater than 8, the highest 8 bits of the interpolation component would be taken into account for interpolation.
3.6.5.5 State machine of the cam generator
"init" state
The cam generator is in "init" state, if bit 0 = 0 and bit 1 = 0 in Z159.3– State.
If the cam generator is in "init" state, changes can be made at the parameter settings.
It is checked, if a valid cam was loaded and if an output parameter was selected, during
the transmission from "init" to "active". If the parameter-controlled processing mode is
configured, the cam checks, if an input parameter was configured. It also checks, if the
count of the supporting points complies with power 2 during a cyclical processing within
this operating mode. If the cyclical offset is generated from the cam data, then this is executed during the transmission from "init" to "active". It also checks, if the reference parameter was selected at the preselected relative mode.
"active" state
The cam generator is in "active" state, if bit 0 = 0 and bit 1 = 0 in Z159.3– State.

Set Value Generators
The cam is waiting for the final command to start processing, if it is in the "active" state.
If the active relative mode is activated, the reference value is frozen during transmission
from "active" to "run", in order to use this value at the next processing.
"run" state
The cam is in the "run" state, if bit 0 = 1 and bit 1 = 1 in Z159.3– State. The cam generator processes the loaded cam in "run" state.
3.6.5.6 Limiting of output value
Because the cam is intended for the generation of the positioning set values for an axis,
the output value is available in the value range of an unsigned 32 bit value. If the output
value exceeds the maximum value of 0xFFFFFFFF, then the output overflows and the
output value starts at 0 again. The cam generator can write to a target parameter of another data type, as well. However, in the range of 0x0 to 0xFFFFFFFF, only.
If the value, which is to be written on the parameter, is greater than the maximum value
or lower than the minimum value of the target parameter, then the output of the cam generator is limited. Bit 7 in the Z159.3– is set, if the output is limited. Then the processing
of the cam is exited. Now, the cam generator is in the "active" state.
Behavior of signed integer parameters:
– If the maximum value of the parameter is negative, the maximum value is written on
this parameter.
– If the output of the cam is greater than the positive maximum value of the parameter,
then this maximum value is written on the parameter.
– If the output of the cam generator is smaller than the positive minimum value of the
parameter, then this minimum value is written on the parameter.
Behavior of float parameters and of unsigned, integer parameters:
– If the output value is greater than the maximum value of the parameter, then the output is limited and this maximum value is written on the parameter.
– If the output value is lower than the minimum value of the parameter, then it is limited
and the minimum value is written on the output parameter.
Additionally, the bits of the output value are the same length as the parameter
(uint16  16 bits; uint8  8 bits) at unsigned and integer parameter. Thus, the cam
can write uint16 parameters and uint8 parameters cyclical endlessly. These parameters
can overflow.
3.6.5.7 Handling the cam data
The cam data is filed in the parameter set file. Therefore, the cams are accepted easily,
if operated in another device.
A single cam is always loaded into the RAM of a controller. The cam must be written into
the flash, if it shall be available after a restarting. This is executed, by saving the complete
parameter set in the flash. Therewith, the cam is saved in the flash, also. If the device is
booted, an available cam in the flash is loaded with the parameters and now is available
in the cam generator.

Motor potentiometer
Changes of the speed set value can be forced by the motor potentiometer depending on
two control bits (Motor potentiometer+ and Motor potentiometer-). The motor potentiometer writes directly on the ramp function parameter Z110.5– Input 16 bit.
The motor potentiometer is activated via the control parameter Z168.2– Mode.
The motor potentiometer parameter Z168.6– Increment indicates the amount of the increase/decrease of the motor potentiometer output Z168.3–.
Parameter Z168.2– bit 4 sets whether the motor potentiometer function operates edge
sensitive or level sensitive:
m edge sensitive
At increasing edge of Z168.2– bit 1 Motor potentiometer+ or Z168.2– bit 2 Motor
potentiometer-, Z168.6– Increment is added or subtracted once.
m level sensitive
At increasing edge of Z168.2– bit 1 Motor potentiometer+ or Z168.2– bit 2 Motor
potentiometer-, Z168.6– Increment is added or subtracted every 32 ms.
The output of the Motor potentiometer is limited by an upper and a lower limit.
The output of the Motor potentiometer is set to 0 or is synchronized with the ramp function
generator parameter Z110.5– Input 16 bit depending on parameterization of Z168.2–
Mode bit 3 at activation of the Motor potentiometer.
The output of the motor potentiometer Z168.3– is checked for limits and if necessary adjusted in case of Motor potentiometer +/- is activated. If the upper limit is changed so that
the output of the Motor potentiometer is greater than this limit, the output is adjusted
downwards with an activated Motor potentiometer+ function. The modification occurs directly without transient.

Overview of the Position / Speed controller module in the drive
Figure 104:
Overview of the Position / Speed controller in the drive
The Position / Speed controller has the task of controlling its output, the torque-producing
current, so that the control deviation is minimized, i.e. the actual value always follows the
set value.
The Position / Speed controller module incorporates the functions:
m Position controller
m Speed controller
m Torque control
m Gear function for synchronous operating mode
The functions are activated by the drive manager. They depend on the drive type set
(Z109.1–) and on the drive state (inhibited or enabled).
With the position controller, the target position generated by the set value manager and
the actual position measured by the encoder system are compared and evaluated in the
P-controller (Z18.14– Kv). In conjunction with the secondary speed controller, a requirement for torque current is generated and then passed to the motor manager. The position
controller contains an adjustable speed feedforward (Z18.15–).
With the speed controller, the target speed generated by the set value manager and the
actual speed measured by the encoder system are compared and evaluated in the PI
controller (Z18.24– Kp, Z18.25– Tn). A requirement for torque current is calculated and
then passed to the motor manager. The speed controller contains a further PT1 element
for smoothing the actual speed, a notch filter for speed actual value and an adjustable
acceleration feedforward (Z18.36–, Z18.37–).

Controllers
With torque control, the controller receives the torque current from the writable parameter
Isq-set value for torque control (Z18.50–). The torque current is then passed to the motor
manager. The parameter value for the torque current can be specified from analog inputs,
for example, or from the Fieldbus.
If the synchronized drive operating mode (Z109.1– = -5) is activated and at the same time
the synchronized operating mode (Z145.2–) "Synchronized operation on a real master
shaft“ is set, the set values from the set value manager are overwritten. The electronic
gearbox (Z145.3– und Z145.4–) is then computed. The set values for the controller are
then calculated from the set value at the gearbox output.
In the "Synchronized operation on a virtual master shaft" mode the set values, including
the electronic gearbox, are calculated in the Synchronized Operation module and forwarded to the position and speed controllers via the set value manager.
The module incorporates a set value interpolator which converts and interpolates or extrapolates the set values from the set value manager in the controller cycle.

3.7.1.3 Description of the Parameters
18.4
Controller actual operation mode
This parameter shows the currently effective operating mode of the Position/Speed Controller module. Depending on the drive state and operating mode, which are set by means
of Parameter Z109.1– the corresponding controller and functions are activated in this
module. When the drive is inhibited, the module is switched off (= 10 = Measure).
The parameter must not be confused with the Actual Operating Mode parameter
Z109.2–!

Adaptation time parameter
To prevent excitation, any change to the Gain parameters Kv (Z18.14–) or Kp (Z18.24–
) when the position or speed controller is switched on is made in stages. I.e., during any
change to the controller parameter Kv and Kp, the newly entered value only becomes fully
effective after the time registered here [ms]. 
The step time is fixed at 50ms for this.
Example:
Z18.7– = 1950 ms
A change of Kp or Kv from the old value to the new one is performed in 39 steps
(1950ms/50ms).

Kv position controller
Proportional gain of the position controller, units s-1.
The position controller is implemented as a P-controller.
It follows from this that with a Kv = 0 the position controller makes no contribution to the
speed set value, as any control deviation (e1 position controller error) is multiplied by the
Kv factor.
18.15
w2-Feedforward factor
Weighting factor for the speed feedforward at position control.
The speed feedforward is implemented as DT1 element. All changes to the position set
value are differentiated with respect to time, multiplied by the parameter w2-Feedforward
factor and smoothed subsequently with the Z18.70– w2-feedforward time constant. From
this it follows that at speed feedforward of 0 the speed feedforward makes no contribution
to the Z18.21– speed set value.
With speed feedforward of 1 (=100%) and constant change per unit time of the position
set value, the speed feedforward provides exactly the required speed set value. In this
case the position controller provides only the correction set value for tracking the angle.
18.17
w2 speed feedforward
The parameter shows the actual output value of the speed feedforward, i.e. the value after the w2-Feedforward factor Z18.15– and the w2-Feedforward time constant Z18.70–.

Factor for acceleration feedforward during the braking phase; a value of 1 corresponds to
100%.
Friction assists during braking, so a reduced feedforward during braking can make sense.

w3-Feedforward time constant
Time constant of the acceleration feedforward for the speed controlled operating modes.
The w3-feedforward is implemented as DT1 element. All changes to the speed set value
are differentiated with respect to time, smoothed with the time constant >18.39< and multiplied subsequently with Z18.38– w3-Feedforward actual factor.
The smoothing via >18.39< does not affect at position controlled operating modes. Here
an already smoothed acceleration set value is available, whose smoothing occurs via parameter Z18.70– w2-Feedforward time constant.
18.40
Ks scaling factor
The value entered here should correspond to the "system gain" in [acceleration /A]. The
inverse value (1/Ks) is used in the controller as a standardization constant between the
acceleration set value (speed controller output) and the torque current set value (Isq).
Thus the parameter Ks is a measure of the acceleration capability.
If Ks has been correctly determined and entered, the Kp for the speed control circuit set
in the parameter has units of [s-1] and is thus independent of the present control process.
This also means that if Ks has not been correctly determined, then Kp does not have units
of [s-1] and is also not comparable with the controller settings in other applications.
m Calculation of Ks:
m Example - motor without load:
DS100M25 motor: Kt = 2.7 Nm/A, J = 141 kg cm² = 0.0141 kg m²
Ks = Kt/J = 2.7/0.0141 = 191.5 rad/s² /A = (from rads to degrees, *180/pi or 57.3)
Ks = 10973 degrees/s²/A
m Example DS100M25 motor with load via a gearbox, encoder on motor side:
Load moment of inertia 0.9 kg m², Gear factor GF = 3 to 1, 
motor turns faster

Controllers
Total moment of inertia, converted to encoder side (here, motor side):
J = JM + JL/GF² = 0.0141 + 0.9/9 = 0.1141 kg m²
Ks = Kt/J = (2.7/0.1141) *180/pi = 1356 degrees/s²/A
m Determination of Ks:
The Ks of the present system can be determined manually by means of an acceleration
test. To do this, the controller is subjected to such a large set value step change that the
torque current rises to the specified limit (i.e., large acceleration and not too low a torque
current limit).
By measuring the time for a measured change in speed with limited current, Ks can be
determined.
Ks = change in speed / (time * torque current)
in [degrees/s²/A]
So that the frictional forces present in the system do not distort the measurement, Ks
should represent the mean of 2 measurements (acceleration and braking):
Measurement 1: Final speed > Starting speed
Measurement 2: Final speed < Starting speed
Ks can also be determined by the FFT Analyzer module or the Ks measurement module.

Controller adaption
Speed controller adaption
At low speed the control deviation is very low and these deviations can not be compensated fast enough. Therefore often a stronger controller is required for low speed.
The parameters Kp and Ki of the speed controller are adapted depending on the speed
with the speed controller adaption. Two or three interpolation points can be specified for
the adaption. If the mean speed threshold (Z155.15–) is set to 0, the adaption is executed
with two interpolation points.
The specified factors will be multiplied by the regular values of Kp (Z18.24–) and Tn
(Z18.25–). Kp and Ki will be interpolated linearly between the both speed limits, where Ki
is calculated from Kp and Tn.
The resulting adapted value of Tn is calculated from the adapted values for Kp and Ki.
This calculation of Tn is executed with low priority, because Tn is only for display.
The adaption can be calculated alternatively depending on the speed actual value or on
the speed set value. In position control the adaption can additionally be calculated depending on the speed feedforward.

Characteristics of Kp and Tn depending on the speed
In ZFig. 113– the characteristics of Kp and Tn is shown due to the speed controller adaption. While Kp is linear, Tn mostly has a hyperbolic shape.
If the middle speed threshold is parameterized to 0, the middle interpolation point is not
applicable and the adaption is executed between the upper and lower threshold.
Cyclical Ks adaption
The torque of inertia changes at some applications. This requires a cyclical change of the
Ks factor and can be adapted via the control and parameter Z155.14–.
The Ks value is updated in RT1 cycle.

3.7.3
Current Controller
The "Current Controller" module incorporates the measurement of the phase currents
and DC link voltages, current control including prediction, dead time compensation and
PWM.
3.7.3.1 Current Prediction
The current prediction can be switched off. The voltage equations for the machine form
the starting point for the current prediction.
3.7.3.2 Dead Time Compensation
Since real semiconductor components do not behave ideally, it must be ensured that the
two transistors in a half bridge are never conducting current at the same time, i.e., are
switched on. For this reason, both IGBTs in a half bridge must be switched off for a certain
time, giving rise to dead times which are different for the individual output sections and
furthermore depend on the switching frequency of the power transistors. Due to these
dead times, a part of the theoretical nominal voltage for the PWM is lost. The dead time
effect produces a non-linear distortion in the voltage space vector. The dead time compensation Z47.50– is intended to compensate for the lost voltage.
The required voltages for the dead time compensation are determined from the sign of
the separate phase currents, the Udc actual value and current depending correction table
Z123.15–.
The table Z123.15– can be determined by autotuning (dead time measurement Z123.1–
bit 1 = 1). The measured values are valid for the parameters which are available at the
moment of the measurement: Udc actual value, PWM frequency and locking time (IGBT
dead time Z129.9–). If the dead time measurement is not executed, the table Z123.15–
has default values defined for Udc = 540 V, PWM frequency = 8 kHz, and locking time =
4 µs.
The effective voltage of the dead time compensation is corrected according to the Udc
actual value (regardless whether the table includes default values or measured values).
Basically the correction table is only valid for the device which carried out the dead time
measurement. However the values of the table can be transferred from one device to another one with the parameter set. In all probability, the dead time compensation will operate satisfactorily if the device is of an identical type. However, this must be checked by
the user. It is recommended to measure the dead time at each device, which requires
dead time compensation.
NOTE!
The dead time measurement must be repeated, if the IGBT dead time (Z129.9–) was
changed.

NOTE!
Up to firmware version V01.08: The dead time measurement must be repeated if the
PWM frequency is changed.
From Firmware version V01.09: If the correction table Z123.15– is measured from
firmware version V01.09 onwards and the adaption of the dead time compensation
according to the PWM frequency is active (Z123.1– bit 3 = 1), the effective voltage
of the dead time compensation is corrected according to the effective PWM frequency. A new dead time measurement after a change of the PWM frequency is therefore
not necessary. However the best results are generally reached if the used PWM frequency corresponds to the PWM frequency at the moment of the dead time measurement.
3.7.3.3 Limiting
The torque current limiting acts on the integral term of the speed controller and on the output of the motor manager before the current is forwarded to the current controller.
There is no limiting at the output of the speed controller because a digital filter can be inserted between the speed controller and the motor manager, or an Isq can additionally
be fed into the motor manager.
The torque current limiting can be set separately for motor or generator operation. By
adapting the "Iq Limiting Mode" Z138.1–, the separate limiting can alternatively be applied to Torque Direction 1 or Torque Direction 2. For "asymmetric" limiting, operating
quadrants 1 to 4 are evaluated using the present speed and torque current. Hysteresis
Z138.4– can be set when determining the operating quadrants.
A symmetrical limiting Z138.14– s available in addition to the limit dependent on quadrants. This limiting is intended for a fast cyclic access via analogous input or fieldbus process data.
Always the less value of both limtis is effective! The effective limit values are displayed in
Z138.6– Iq Upper Limit and Z138.7– Iq Lower Limit.
Particular case synchronous motor with interior permanent magnet (IPMSM)
The Iq current is not limited, but the total current is limited at IPMSM, because both currents contribute to the torque production.

Breakdown Torque
In BM3300 the current torque is limited by a speed limit. The Ud-voltage may not exceed
50% of the total voltage:
U Zk
U D,Max = ------------------ =  el  L q  i q max
6 2
The inception speed can be defined from this requirement:
60U Zk
60 el
n E = -------------- = -------------------------------------------------2p
2p 12  L q  i q Max
Additionally the inception speed is adjusted over the parameter Z138.17– (factor for
Breakdown torque). The actual inception speed (Z138.16–) is calculated with the above
mentioned formula multiplied with Z138.17–.
The inception speed is standardized to a DC-link voltage of 540 V. The inception speed
is adjusted to the present voltage.
3.7.3.4 Feedforward
Decoupling feedforward
The decoupling feedforward compensates the influences on the field forming current to
the torque of the machine. Vice versa the influence of the torque forming current on the
field of the machine is compensated.
Electromagnetic force feedforward
There is the possibility to feedforward the electromagnetic force for the current controller
of the torque forming current component. This feedforward can be switched off by entering the value 0 in Z107.20– Ke factor. The actual Ke factor of the machine must be entered in Z107.20– for a correct feedforward of the electromagnetic force.
IxR feedforward
The IxR feedforward compensates the voltage drop at the ohmic resistance of the stator
winding for both the field forming and the torque forming current controller. This feedforward is generally deactivated and can be activated via parameter Z47.51–, if required.
Additionally it is possible to execute the feedforward based on the actual current values
or based on the current set values. This must be also set in parameter Z47.51–.
For the used stator resistance the decisive factor can be either the parameter value
Z107.29– (Motor data) or the parameter value Z123.6– (measured resistance). It depends on the parameterization of parameter Z123.10–.

P-gain reaches a limited percentage KpAdapt Z155.13– of the original P-gain. The adaption results from the current set value Z47.1–.
3.7.3.6 Pulse Width Modulation
Switching between Space Vector Modulation (SVM) and Modified Space Vector
Modulation (MSVM).
With MSVM it is possible to reduce the average switching frequency of the IGBTs by a
third, with the result that the average switching losses are also reduced by a third. With a
high duty cycle, it is particularly advantageous to use the modified SVM process (MSVM).
With a smaller duty cycle it is certainly also possible to reduce the switching losses by a
third, but the switching current ripple can be up to twice as great as with normal SVM.
The lower the stator frequency becomes, the more slowly the current space vector rotates. In the extreme case it can even be stationary. For the IGBTs in the three half bridges, the concept of average thermal loading can no longer be used here as for a higher
stator frequency. For certain IGBTs it is then also no longer possible to reduce the losses
with this procedure.
Parameter Z47.40– PWM MSVM Threshold is used to select the PWM duty cycle from
which MSVM is activated.
This parameter can be set from 0.00% to 100%. A value of 0.00% corresponds to zero
voltage at the inverter output; 100% corresponds to 100% PWM duty cycle. From a duty
cycle of 80% the switching losses are reduced by a third with MSVM, without increasing
the switching current ripple compared to SVM.

DC link controller
3.7.4.1 Description of the DC link controller
The controller for the DC link voltage, the DC link controller in short, is a PI controller
which acts on the current limit.
The controller does this by limiting the generator current, because in generator operation
(while braking the drive) the DC link voltage rises as a result of the current that is fed back.
Depending on the direction of revolution, either the upper or the lower limit of the Iq current is adjusted.
3.7.4.2 ProDrive DC link controller
Figure 117:
ProDrive DC link controller
3.7.4.3 Reactive current brakes
The dynamic at a braking process drops if there is no brake resistor, because the energy
of the motor must be reduced. Additional energy in the motor can be reduced by applying
reactive current.
The Udc link-ld controller uses the same controller parameter as the Udc link controller.
The maximum Id current is applied as soon as the DC link voltage exceeds the maximum
value (Z114.1–).The Udc link-ld controller operates with a 99% threshold of the maximum value. There is maximum reactive current during the braking process-reactive current is reduced if the Udc link controller isn't operating anymore. The Udc link-ld controller
is switched on via Z47.51– with bit 4.

Description of the Software Modules and Parameters
Synchronous motor
The set ld current set value (Z19.9–) is supplied at a synchronous motor. The current
should be supplied negatively at high speed as otherwise the required voltage could get
too high.
Asynchronous motor
The maximum Id current (Saturation magnetizing current Z146.12–) is supplied at an
asynchronous motor. The motor flux increases with the Id current and thereby the required voltage. The field weakening controller counteracts the Udc link controller and the
maximum Id current cannot be supplied, if the required voltage exceeds the available voltage.
At high speeds it is possible to supply block-shaped Id current with the output of the Udc
link-ld controller. At this process the flux increases and decreases dependent of the ld
current signs. The sign of the ld current changes, if the actual flux value (Z146.14–) exceeds the limits, which are between 100% of the flux set value and the adjustable threshold (Z114.8–).The block-shaped ld current is supplied above the adjustable threshold
(Z114.7–) - below the threshold positive ld current is supplied, only.
3.7.4.4 Short circuit brake
Synchronous motors are able to be braked using a short circuit brake, additionally. If the
DC link voltage exceeds a set threshold, the motor phases are shorted and the current
no longer flows into the DC link. The motor is decelerated by the resulting current.

3.7.4.6 Description of the DC link controller parameter
114.1
DC Link controller set value
Maximum value for the DC link voltage.
During braking procedures, energy is fed back from the motor into the DC link, which is
further charged as a result.
On devices that do not have regenerative capability, the energy can only be dissipated
via a chopper resistor.
to prevent the DC link voltage from rising too far, it is limited to the maximum value set
here by means of a control arrangement. To this end, the deceleration torque in the drive
is reduced if necessary, so that the DC link voltage does not rise any further.
114.2
P-Gain of DC link controller
P-gain of the DC link controller.
Standardization: the controller output limits the permissible Iq current in the generator
mode. Output = 0.5 means Iq should be a maximum of 0.5 * Z138.6– or Z138.7–.

114.5

The output of the DC link controller effects a current limit on Iq between 0 and the upper
limit of the torque current (Parameter Z138.6–) in generator mode. The parameter displays the present positive current limit.

Current negative limit
The output of the DC link controller effects a current limit on Iq between 0 and the lower
limit of the torque current (Parameter Z138.7–) in generator mode. The parameter displays the present negative current limit.
114.7
Speed threshold for block shape current
If the Udc link-ld controller is switched on block-shaped ld current is supplied above this
threshold.
Below this threshold the current is increased only in order to reduce the braking energy.
Braking with block-shaped ld current can be switched off, if the value of the speed threshold is set above the maximum speed.
114.8
Flux threshold
The flux is minimal with block-shaped ld current. If the actual flux drops below this threshold the sign of the ld current is changed.
114.9
DC link voltage hysteresis
If the DC link voltage drops below the maximum value (Z114.1–) by this value, the torque
current is no longer limited.

3.7.5
Field weakening
At an asynchronous machine as well as at a synchronous machine regarding the operating range it is commonly distinguished between the basic speed range (typically below
the rated speed of the motor) and the field weakening range (typically above the rated
speed).
In the base speed range the flux remains constantly. In the field weakening range the flux
is reduced (ASM) or negative lsd current is applied to make greater speed possible at an
insufficient DC-link voltage
Field weakening factor
The field weakening at the voltage limit (Z142.1– bit 0 = 1) at b maXX 5000 is structured
accordant to the field weakening factor (see diagram in figure 125). The field weakening
factor represents the current level of the field weakening. The field weakening factor (parameter Z142.2–) is a factor without units, value range is between 0 … 1.
ZFig. 118– shows that the field weakening is made via two channels. The first channel is
an open-loop controlled and the second channel is a closed-loop controlled field weakening.
Open-loop controlled field weakening
If the speed exceeds a specified speed threshold the flux is reduced after a characteristic
(see ZFig. 118–) inversely proportional to the speed. As a speed threshold either the parameter Speed threshold field weakening (Z142.9–) acts, if bit 1 was set by the field
weakening mode Z142.1– or the rated speed (Z142.7–) if this bit was not set. The output
of the open-loop controlled field weakening is the field weakening factor after the speed
Z142.12–.
Closed-loop controlled field weakening
The second channel contains a voltage controller that evaluates the difference between
the specified limit and the actual value of the motor voltage (parameter Z142.7–) and accordingly weakens the flux, so that the motor voltage doesn't increase anymore. The limit
is the lower one of two values of the voltage threshold specified via the parameter
Z142.8– and of the maximum output voltage (Z142.6–). The maximum output voltage is
continually calculated from the current DC-link voltage provided that there is a full PWM
control. The output of the closed-loop controlled field weakening is the field weakening
output Z142.13–.
Total field weakening factor
The a present degree of the field weakening (Field weakening factor Z142.2–) is given
by the lowest value of two channels (minimum value between Z142.12– and Z142.13–
). This is additionally limited, so that it never falls below the specified limit of the parameter
Minimum field weak factor (Z142.5–).

Special case: Permanent field current
The field weakening mode "permanent field current" (Z142.1– bit 0 = 1) makes it possible
to apply the field current set value Z19.9– permanently (lsd set value Z142.2– = Field
current set value Z19.9–). In this case the field weakening factor is without effects. Therefore, the flux controller is deactivated at the ASM (flux set = flux actual).
Mode of operation of the field weakening factor
The field weakening factor at the ASM directly influences the current flux set value and at
the SM the field current set value as follows (also see diagram in ZFig. 119–):
m Asynchronous machine (Z142.1– bit 0 = 0):
Flux set value in % Z146.13– = Field weakening factor Z142.2– * 100

Field weakening factor
The field weakening factor represents the current level of the field weakening.
The field weakening factor is without units. The range of values extends from 0 to 1.
The field weakening factor accords to the minimum value between field weakening output
Z142.13– and the field weakening factor after the speed Z142.12–.
Furthermore, the field weakening factor of the parameter Z142.5– "Minimum field weak
factor" is limited:
Field weakening factor [Z142.2–]  Minimum field weak factor [Z142.5–].
Further details see chapter ZField weakening– from page 435.

P-Gain of field weakening controller
Proportional gain of field weakening controller.
With a SM, the field weakening controller can be set more finely than with an ASM, as no
delay in the reduction of the field due to the rotor time constant occurs.
A P-gain of 0 switches off the field weakening controller.
142.4
Field weakening controller integral action time
Reset time of the field weakening controller.
At value 0 the integral part is set to 0 and the field weakening controller works without integral part.
142.5
Minimum field weak factor
The parameter is without unit and serves as a limit of the field weakening factor Z142.2–
The range of values extends from 0 to 1.
Field weakening factor [Z142.2–]  Minimum field weak factor [>142.5<].
Of importance only if the field weakening type at the voltage limit is set (Z142.1–
bit 0 = 0).
See chapter ZField weakening– from page 435.
Considering the extreme cases:
Minimum field weak factor = 0
For SM: The parameterized field current set 
value Z19.9– can be reached.
For ASM: The flux set value Z146.13– can 
be reduced to 0%
Minimum field weak factor > 0
For SM the parameterized field current set 
value Z19.9– can not be reached.
For ASM the flux set value in % can only be 
reduced to 100 * "Minimum field weak 
factor".

Two-level controller
3.7.6.1 General
The b maXX® controller has 2 two-level controller, which independently are operating and
which are freely configurable. With the two-level controller 1 fixed and variable switching
thresholds can be monitored. At the two-level controller 2 there are no relative switching
thresholds. The operating mode of the according two-level controller is configurable.
Depending on the data type of the input parameter the corresponding parameter for the
lower and upper switching threshold must be selected.

Description of the Software Modules and Parameters
3.7.6.5 Sign-independent monitoring
By setting Z151.1– Mode bit 2 the controller generates the absolute value of the actual
value and compares this with the thresholds which accordingly must be positive. Application for this purpose e. g. speed monitoring (independent of positive and negative rotational direction).
3.7.6.6 Linking of the controller output with the target parameter
The output of the two-level controller can directly be used to change a writable controller
parameter. This method is related to that of the digital inputs. All cyclic writable parameters can be used as a target parameter.
When switching off a two-level controller the bit pattern at the output is not changed.
A change of the bit masks or values affects at next switching of the two-level controller.
Meaning of the linking parameters:
Parameter name
Meaning
Target parameter number output
Target parameter number
Bit selection
Selection of the bits in the target parameter, which
have to be changed
Bit pattern at LOW output
Bit pattern, which is written in the target parameter at
controller output LOW.
Bit pattern at HIGH output
Bit pattern, which is written to target parameter at
controller output HIGH
At a positive edge of the two-level controller output the target parameter is changed as
follows:
Target parameter =
(target parameter and not (bit_selection))
OR (bit pattern at high AND bit_selection)
At a negative edge of the two-level controller output the target parameter is changed as
follows:
Target parameter =
(target parameter and not (bit_selection))
OR (bit pattern at low AND bit_selection )
If an error occurs at writing to the target parameter (e. g. value greater than the maximum
value or smaller than the minimum value), by the controller an according error message
occurs.

The output of the field weakening controller is the set value of the flux controller at asynchronous machines. The flux controller is a simple PI-controller with proportional gain Kp,
integral time Tn and limitation. The Isd-set value is at the output of the flux controller.
Figure 125:
ProDrive Flux controller
The actual flux value is calculated from an asynchronous machine value. If the Kp of the
flux controller is set to 0, the inverse of the Imr-flux-characteristic is set for the Isd-set value.

Description of the Software Modules and Parameters
3.8.1.1 Moving to positive stop command
With this function it is possible to move with an adjustable torque against a mechanical
stop without an error message or an error switch off by the controller. The function can
be used to fix a component for instance.
Requirements:
m The command is only available in the "Position control with synchronous position set
value specification (-4)" operating mode. The command is ignored at all other operating
modes.
m The command cannot be used with master-slave torque coupling or gantry axes.
m The "N=0" message must operate correctly. Therefore the parameter Z6.1– Standstill
threshold must be greater than the noise of the speed actual value at standstill always.
m The specified speed set value during the command must be greater than the standstill
threshold.
m The parameters Z120.11– Homing blocking time and Z120.12– Homing torque limit
must be set properly. On the one hand the reduced torque limit must be selected great
enough in order to decide safely the reaching of the torque limit, on the other hand the
reduced torque limit must be selected small enough in order to exclude a damage of
the positive stop.
Options:
The options can be adjusted in parameter Z121.23– Mode positive stop drive.
m Monitoring of the positive stop
The stop at the positive stop can be monitored by a symmetrical monitoring window. A
new drive error is generated if the position actual value is out of this window.
The n=0 message can be monitored instead of using the monitoring window.
The error reaction can be set on demand. Default reaction = pulse inhibit.
m The reduction of the torque limit can be switched off via Z120.12–.
Process:
The command is enabled by setting bit 0 in Z121.21–. The controller acknowledges this
by setting bit 0 in Z121.22– Status positive stop drive. The controller reduces at once the
torque limits by means of the set values in Z120.12– Homing torque limit, i.e. moving
against the positive stop occurs with reduced torque limits. The master control provides
the speed profile in the position control operating mode and must therefore consider the
available reduced torque in the set value profile. The blocking monitoring, position error
monitoring and the speed control deviation monitoring are switched off in the controller
when starting the command.
The messages "N=0" (Z6.2–) and "Torque current set value is limited" (Z18.20– bit 13)
are used to detect the positive stop. Copies of these messages are available in the bits 8
and 9 of the Z121.22– Status positive stop drive. The copies are available only during on
active command.
The controller sets the message "Positive stop reached" when both conditions are fulfilled
during Z120.11– Homing blocking time. Simultaneously with the setting of the message 
the effective position actual value at the stop position is stored in parameter Z121.4–, the
optional positive stop monitoring is activated and the cyclic set values from the master
control are ignored.

Document no.: 5.12001.06

3.8
Operating Modes
The monitoring of the stop at the positive stop is enabled until the command is disabled.
The master control must now synchronize its position set value with the effective position
actual value and can then transmit the new set value to the controller.
The disabling of the command is done via bit 0 = 0 in Z121.21–. The positive stop monitoring is disabled, the three switched off monitorings are enabled again, the torque reducing is disabled and the set values of the master control are effective in the controller
after disabling the command.
NOTICE!
1
The motor can be destroyed at active command, because the blocking monitoring
of the controller is switched off during the command and therefore a blocking,
which is not caused from a positive stop, does not result in a switch off.
2
The device can be damaged at active command. The user must avoid this by a
proper set value profile (maximum acceleration, maximum speed) and by enough
reduced torque limits.

The causes for that could be:
n Both hardware limit switches are active at the same time.
n Positive software limit switch and negative hardware limit switch are active at the
same time.
n Negative software limit switch and positive hardware limit switch are active at the
same time.
Possible causes:
n Software limit switches are set incorrectly, e.g. values for positive and negative limit
switches are switched.
n Hardware limit switches are wired incorrectly.
n Errors on the wiring for hardware limit switches.
Effect of Error 905 "Error Limit Switch Monitoring":
A parameterized error action is carried out. If the entry for error response is "no response", the response will occur depending on the operating mode and without pulse
block, which means the current operating mode will remain active.
– Position target entry: Always stop including error message 905.
– Manual operation: Always stop including error message 905.
– Position control with synchr. position set value entry: 
In the case of an error the error message 905 is only generated, if Z136.2– Mode
bit 4 = 1 (drive internal stop) or bit 5 = 0 (error message is activated). For further details, refer to Z136.2–.
– Speed control and speed set value 1: 
In the case of an error the error message 905 is only generated, if Z110.2– Mode
bit 9 = 0 (error message is activated) . For further details, refer to Z110.2–.
However, before the error is reset, the wiring of the hardware limit switches and parameterization of the software limit switches must be checked.
121.3
Negative SW limit switch
This parameter limits the permitted adjusting range with active software limit switch monitoring in the negative direction (= negative output speed).
It indicates the lowest target position that can be approached in operating mode position
target entry.
In operating modes manual operation and position control with synchronous position set
value specification, a stop occurs immediately if there is a drop below the value with the
adjusted stop delay (Z121.8–).
121.4
Positive SW limit switch
This parameter limits the permitted adjusting range with active software limit switch monitoring in the positive direction (= positive output speed).

3.8
Operating Modes
It indicates the greatest target position that can be approached in operating mode position
target entry.
In operating modes manual operation and position control with synchronous position set
value specification, a stop occurs immediately if the value is exceeded with the adjusted
stop delay (Z121.8–).
121.5
Positioning window
Operating mode position target specification (= 1) and spindle positioning (= -6): If the
drive reaches a window around the new target position, the "Position target reached" bit
will be set in the status word. The positioning window is symmetrical surrounding the target position and is determined with this parameter.
Operating mode reference run (= 6): The positioning window for standstill recognition is
used with Set Home Position.
Additionally the parameter is used in all position controlled operating modes for generating the "In Position" message (bit 6 in Z121.18– Status). If the absolute value of Z18.60–
Position error rev+angle is less than the positioning window, the drive generates the message "In Postion".
121.6
Positioning window time
This parameter is used to prevent that the "Position target reached" bit is set when the
briefly moving across the positioning window. The time during which the drive must be
located in the positioning window before "Position target reached" is set must be determined.
If the drive is pushed out of the positioning window again, such as through the load, "Positioning target reached" will be deleted again. The next dip into the positioning window
will restart time monitoring.
121.7
Feedrate override
This parameter can be used to adjust a previously adjusted target speed "online" (during
movement). The factor affects the following speeds:
n Max. positioning speed of the active positioning set in the operating mode position
target specification (= 1)
Vmax = Vpos * Feedrate Override / 100%
n Tipping speed 119.3 in the operating mode manual operation (= 5)
Vmax = Vtipp * Feedrate Override / 100%
Limiting to the maximum speed of the drive occurs according to the multiplication with the
Feed rate Override.

Special cases:
n When the multiplication with the feed rate override results in a maximum speed of

121.8
Stop delay
The stop delay describes the maximum permitted deceleration of the drive with the stop
request through a limit switch or command through the control word.
121.9
Positioning position actual value
This parameter shows the current position actual value. The parameter is updated with
the cycle time of the fieldbus task Z1.10–.
121.10
Maximum position value
This parameter shows the maximum possible position value with the set position resolution.
It is calculated as follows:
Maximum revolution = whole-number result from FFFFFFFFhex / position resolution
When the position resolution is a squaring, then the maximum revolution must be increased by one.
Maximum position value = (Maximum revolution * position resolution) - 1
NOTE!
For Motion Control applications, the position resolution is permanently set to 65536
Inc/revolution!
The result is a maximum position value of FFFFFFFFhex.
121.11
Speed limit
Bipolar limit to limit the output speed of the positioning operating modes.
Additionally the Z107.26– maximum mechanical speed of the motor for determination of
the effective speed limit in the below-mentioned operating modes is used for the protection of the motor and the mechanical setup.The lesser value of the parameter Z121.11–
and Z107.26– is effective.

Operating Modes
If the value 0 rpm is entered in Z107.26–, the value is ignored at the determination of the
speed limit, i.e. Z121.11– is effective.
Reference run (Operating mode 6):
If the set Z120.5– Homing speed exceeds the effective speed limit (Z121.11– and
Z107.26– respectively), the speed will be reduced to the value of the limit and Bit 6 is set
in the Z120.1– Status.
Position target specification (Operating mode 1) and manual operation (Operating
mode 5):
If the set Z118.11– positioning speed or Z119.3– tipping speed multiplied with the
Z121.7– Feed Rate Override exceeds the effective speed limit (Z121.11– and Z107.26–
respectively), the speed will be reduced to the value of the limit and Bit 6 is set in the corresponding operating mode status (Z118.1– or Z119.1–).
Position control with cyclic set value specification (Operating mode -4):
The input position values including offset parameters (Z136.3– to Z136.7–) are monitored for overspeed. If the resulting set value speed exceeds the effective speed limit
(Z121.11– and Z107.26– respectively), the speed will be reduced to the value of the limit, the error 910 "Overspeed detected at the set value input" will be triggered and Bit 6 will
be set in the Z136.1– Status.
Spindle positioning (Operating mode -6):
If the set spindle positioning speed Z149.4– exceeds the effective speed limit (Z121.11–
and Z107.26– respectively), the speed will be reduced to the value of the limit and Bit 6
will be set in the Z149.1– Status.
121.12
Position actual value revolutions with overflows
This parameter shows the current revolutions of the position actual values including the
revolution overflows Z106.15–.
The parameter is initialized at each encoder initialization, considering the sum of revolutions of the encoder actual value (encoder for position controlling; see Z18.9–) and the
number of revolution overflows. If the overflows of Z106.15– should be ignored, bit 5 in
Z121.1– must be set.
The parameter has the further characteristics:
m Update with the cycle time of the fieldbus task Z1.10–.
m Bit 4 in Z121.1– must be set for calculation.
m The parameter counts to the maximum value of Z137.2– * Z106.16– / 2 
(Z106.16– Revolution overflow counter max value and
Z137.2– Number of revolutions (= "Multiturn area" of the encoder))
m No control-specific use in the controller

121.15
Modulo revolutions
Modulo value in complete revolutions.
This parameter defines the point in which the revolutions of the Modulo position actual
value should overflow ("turnover") to 0.
Modulo value = 1: The revolutions at the gear output are irrelevant for the Modulo position
actual value.
Modulo value = 0: The revolutions at the gear output will be added to the Modulo position
actual value without modulo division.
The parameter Modulo revolution will be effective only if the following condition is complied with:
Modulo revolutions < (232-1) * Output revolutions Z121.14– / Input revolutions Z121.13–
121.16
Rotation position resolution
This parameter contains the value of the rotation position resolution and defines the value
of the rotation weighting. A value of 3600000 corresponds with a LSB value of
0.0001 degrees.
Rotation resolution = 0: Only the angle of the gear output will be transferred 1:1 in Modulo
position actual value! The revolutions at the gear output are not used and the modulo calculation is not executed.
An exorbitant value in the rotation position resolution can cause an unrequested overflow
in Z121.17– Modulo position actual value. Therefore the following condition applies:
Modulo revolutions * Rotation position resolution < 232

The initialization of the Modulo position actual value is executed at each encoder initialization. The input value of the gear is set. based on parameter Z121.12–. This value is
multiplied with the gear factor (Z121.13– and Z121.14–) and results in the start value for
the position at encoder output. The value at the gear output is multiplied with Z121.16–
Rotation position resolution in consideration of Z121.15– Modulo revolutions.
The parameter has the following characteristics:
m Update with the cycle time of the fieldbus task Z1.10–.
m Bit 4 in Z121.1– must be set for calculation.
m No control-specific use in the controller.
m A homing has no influence on the parameter.

value of the drive is out of the symmetric monitoring window Z121.25– of the positive
stop position Z121.24– or the N=0 message is not available. The selection between
both monitoring possibilities "monitoring window" or "N=0 message" is set in Z121.23–
in bit 0-1.
Bit 5:
Error - Moving to positive stop not possible
The bit is set in case the command cannot be started because of the current operation
state. The error is also generated if the master-slave torque coupling or the gantry function is active.
The bit 0 "Positive stop drive active" of Z121.22– remains 0 in this case.

Target Position Setting (Positioning) Mode
The target position setting mode is a drive-controlled positioning mode. Based on the target position specification, the motion profile is calculated in the drive and the drive is
moved to the target position. The drive can only ever calculate the profile for its own axis.
The positioning operation can be used to implement
m route positioning or
m rotary table positioning
may be implemented.
A trapezoidal profile (optimum time) or an S-curve (jerk-free) can be selected for the
speed profile.
The drive has 16 positioning records (1 ... 16) and one active positioning set (0), in which
the positioning data (e.g. position set value, positioning speed, positioning acceleration,
etc.) are stored.
The positioning data can be changed
m statically (i.e., before the positioning starts) or
m dynamically (during an active traversing process)
may be changed. In the case of dynamic changes, the traverse profile is automatically
adapted to the new positioning data.
The target position can be specified
m absolutely
m relative to the target position or
m relative to the instantaneous actual position ("positioning on the fly")
may be indicated.
During positioning the travel of the drive can be restricted by hardware limit switches and
by freely settable software limit switches. If the drive reaches such a limit switch it will be
braked and a corresponding status message or error message will be generated.
To determine the actual position, one of the supported encoder systems can be used.
Various possibilities for the reference run are given to establish an absolute reference
from the drive position to the travel route for encoder systems that do not provide any absolute position information (e.g., incremental encoders) or for single-turn encoders (e.g.,
resolvers). These are implemented in their own operating mode and will be described in
a separate section.
3.8.2.1 Controlling the Positioning
Two handshake procedures are implemented for controlling the positioning. The selection is defined by Bit 8 in Parameter Z118.2– Mode.

Operating Modes
m Bit 8 = 0: "New Set Value" method (standard method)
Bit 4 "New Set Value" in the drive manager control word is used here. The positioning
set data are copied on each rising edge of this bit (Set X to Set 0), adopted internally
and the positioning procedure started.
m Bit 8 = 1: "Start Positioning" method
The start of positioning takes place with Bit 11 "Start Positioning" of the drive manager
control word.
The following chapters are all based on the "New Set Value" method. The "Start Positioning" method is documented in a separate chapter (see ZControl by Means of the "Start
Positioning" Method– on page 485).
3.8.2.2 Positioning Data
The controller has 16 positioning records (1..16) and one active positioning set (0).
The Current Positioning Set Number parameter Z118.6– defines the positioning set from
which the data will be taken at the next start command (rising edge of "New Set Value"
control bit, control word Bit 4). The data will be copied from the specified positioning set
into Positioning Set 0.
It is also possible to set a mode (see also Z118.2–, Bit 10) in which the positioning data
are transferred and the positioning is started when the current positioning set Z118.6– is
changed. In this case the edge of the "New Set Value" control bit is not required, however
the bit must be set.
There are two different positioning procedures:
m Set specification ("Single set value"): Procedure using individual positioning records: 
With this procedure, a positioning set is started and the drive positions at the target and
holds there. It is possible to activate a new task, even during positioning (edge of New
Set Value). This is then taken up immediately; the drive thus changes directly to the
new positioning data.
The selection of Set Specification depends on the setting in Z118.2– Mode Bit 11.
n Bit 11 = 0: Interpretation of Bit 5 is compatible with b maXX 4400. Set Specification
is selected when Bit 5 is cleared.
n Bit 11 = 1: Interpretation of Bit 5 in accordance with IEC61800-7-201. Set Specification is selected when Bit 5 is set.
m Set Value specification ("set of set values"): Procedure using a speed profile.
With this procedure, several positioning data are activated in sequence. The drive is
not intended to remain at the first target, but rather to activate the next data from the
first target position. 
The selection of Set Value Specification depends on the setting in Z118.2– Mode
Bit 11.
n Bit 11 = 0: Interpretation of Bit 5 is compatible with b maXX 4400. Set Value Specification is selected when Bit 5 is set.
n Bit 11 = 1: Interpretation of Bit 5 in accordance with IEC61800-7-201. Set Value
Specification is selected when Bit 5 is cleared.
The state of the "Change Set Immediately" bit in the control word is evaluated in conjunction with the activation of a motion task, i.e., always on the rising edge of "New Set Value".

Remarks:
m Target position reached
The Target Position Reached message indicates that the positioning target has been
reached. It is only displayed if the "New Set Value" control word bit is cleared. Due to
the handshake procedure, this message is not displayed if the "New Set Value" bit is
set.
An exception is the "Automatic Start after Change of Positioning Set" option (Bit 10 in
Z118.2– Mode). In this case the Set Value Reached message is not suppressed, even
with the "New Set Value" control bit set.
m Set Value handshaking:
Set Value handshaking is the controller's response to a new start command. The drive
sets this bit when the positioning data have been transferred and the positioning has
been started.
The drive clears the bit as soon as it is ready to accept new set values. The controller
may not start any new positioning tasks while this bit is set. In contrast, the data in the
positioning records can be changed.

The controller has sent new data and sets the New Set Value bit again, so that the
data will be accepted. At this point, the drive has not yet reached the first target position.
7
The drive signals that it has accepted the new data by setting the set value handshake. As the old target still has not been reached, the data will not be effective yet.
The new positioning data will only become effective the moment the first target position is traversed.
8
The controller cancels "New Set Value" again.
9
The drive has reached the first target position and now activates the new positioning
data. From this point the drive is ready to receive new set values; the drive signals
this by clearing the Set Value Handshake.
10 The controller has sent new data and sets the New Set Value bit again, so that the
data will be accepted. The positioning data are to be the last data in this setting sequence; the drive should thus hold at the target. Therefore the "Change Set Immediately" bit must be cleared.
11 The drive signals that it has accepted the new data by setting the set value handshake. As the old target still has not been reached, the data will not be effective yet.
The new positioning data will only become effective the moment the first target position is traversed.
12 The drive has reached the second target position and now activates the new positioning data. From this point the drive is ready to receive new set values; the drive signals
this by clearing the Set Value Handshake.
13 The ramp generator reports "Function Ended", however values can still be specified
by the smoothing generator.
14 The drive reports Target Position Reached. This occurs depending on the Positioning
Window and the Positioning Window Time that have been set.
At the set value specification the controller monitors whether it has got the next set value
in time. If the next set value is not in time, error 911 is messaged. The error reaction is
according to the set reaction for this error.
Special treatment of the error response „No response“:
„No response“ is the preset reaction of error 911. „No response“ means here that the drive
will not be locked due to the error and the reaction is done in the operating mode „Target
Position Setting“. In case of error the ongoing positioning will be aborted, the error will be
messaged and the drive will be decelerated to a standstill with the adjusted positioning
deceleration (Z118.13–).
3.8.2.7 Hardware limit switches
Hardware limit switches can be set to restrict the travel range. These hardware limit
switches only act in the Target Position Setting, Jog, and Position Control with Synchronized Set Value Specification modes. Additionally they can be used for reference runs. In
this case they are used as reference marks, not for restricting travel.
The limit switch monitoring is controlled via Bit 1 of Parameter Z121.1– Positioning General Mode. Basically the monitoring is activated or deactivated with Bit 1; Bit 5 of Parameter Z118.2– can be used to define whether an error message should be displayed to
supplement the braking procedure.
The status of the limit switches is always displayed in Parameter Z121.2– State of Limit
Switches, regardless of the operating mode and the other settings.

Operating Modes
Selecting the Inputs for HW Limit Switches
The selection of the inputs for the limit switches is performed with the aid of the parameter
"Operating Mode of Digital Inputs 1 to 8" (see Parameter 116.2 ff. in chapter ZDigital
Inputs– from page 168).
Limit Switch Monitoring
If the Target Position Setting mode is active and the drive is enabled and one of the hardware limit switches is set, the following response takes place:
m In Parameter Z121.2– State of Limit Switches, the corresponding bit for the HW Limit
Switch is set.
m The drive is braked immediately to Speed = 0 with the ramp set in Parameter Z121.8–
Stop Delay.
m Movement further into the switch is inhibited.
m If the "Error message"
response is selected, an error is generated. 
Error 906: Negative hardware limit switch active
Error 907: Positive hardware limit switch active
The error generated does not result in the inhibition of pulses; the drive thus continues
to be position controlled. This error must be reset before a new motion task is executed.
Driving Out from the Limit Switch
If a new positioning task is now started, a check is made of the direction of travel:
New data set drives in blocked direction of revolution:
m The data set is not executed.
m The blocked direction of revolution remains blocked.
m In error generation mode, the error message is generated again.
New data set drives in open direction of revolution:
m The data set is executed.
m The blocked direction of revolution continues to be blocked for as long as the corresponding HW limit switch is set.
The HW limit switches cannot be used to hold (interrupt) a running positioning operation,
as in any case the new target position must drive into the open direction of revolution.
Special case - both limit switches active
If both hardware limit switches are active, both directions of travel will be blocked. A limit
switch must be free again before a motion task can be executed.

3.8.2.8 Software Limit Switches
Software limit switches can be activated in the Positioning, Jog and Position Control with
Synchronized Set Value Specification modes to restrict the permissible travel range. The
software limit switches have no effect in any of the other modes.
The following should apply for setting the software limit switches:
HW Limit Switch 1 < SW Limit Switch 1 < SW Limit Switch 2 < HW Limit Switch 2
The behavior of the limit switch monitoring can be set. There are two different modes:
Automatic Limiting Mode
When the automatic limiting mode is set for the software limit switches, target positions
which lie beyond the limit switch are restricted to the respective limit switch. Thus the
drive stops at the software limit switch. Furthermore, the status flag for the particular software limit switch is set and the Set Value Reached message is not displayed.
Error Message Mode
If the Error Message mode is selected for the software limit switches, the drive issues Error Message 908 or 909, "Software Limit Switch 1 or 2 Active" when the target position
lies beyond the limit switch.
The drive remains position-controlled and does not execute the erroneous task. The affected limit switch is indicated in Parameter Z121.2– State of Limit Switches.
No new positioning tasks will be executed while the error message is present. The error
message must be acknowledged beforehand. The Target Position Reached status message is also not displayed.
If a positioning task with an invalid target position is activated while the drive is still moving, the positioning procedure which is still running will be executed to completion.
3.8.2.9 Target Specifications
The numerical range for positioning comprises 32 bits.
The position values are unsigned. There are two exceptions, the CANopen modes 9 and
12. In these modes a computed range offset of 231 is made between the target position
and the actual position. In this respect, the target should be regarded as a signed value.
There are various possible ways of specifying the target position:
m Absolute target specification
m Relative target specification in a positive or negative direction relative to the last target
position
m Relative target specification in a positive or negative direction relative to the actual position at the time when the task was activated.
m Relative target specification with sign relative to the last target position.
m Absolute / relative target specification:
In this case, Bit 6 of the control word determines whether the target is absolute or relative (relative to the last target). If Bit 6 is set while the edge of "New Set Value" is rising, the target specification is relative. If the bit is cleared, the target specification is
Parameter manual b maXX BM3000
479
Document no.: 5.12001.06
of 724
3.8
Operating Modes
absolute. A relative target specification is signed, however the same parameter,
Z118.9– Positioning Target Position, is used.
m CANopen mode with range offset: 
In this special mode, the distinction between absolute or relative target specification is
also made via Bit 6 of the control word, but for absolute specifications a range offset is
included in the calculation of the target position. In this mode the numerical range for
positioning should be regarded as signed. The target specification is carried out using
parameter Z118.16– Positioning Relative Target Position.
m CANopen mode without range offset:
In this case there is no range offset calculated in the target position for absolute target
specification. Otherwise, this mode is identically with the CANopen mode with range
offset.
m Absolute positioning to angle in positive and negative direction respectively or shortest
way:
In this case only the angle of the target position is used and this angle will be approached in the next possible position.
m Positioning to absolute angle with selectable number of revolutions
In this case it will be positioned to the denoted angle. Thereby the number of revolutions is calculated relatively.
m Absolute modulo positioning with direction select or shortest way 
This type of positioning can be applied at axes on which an endless moving (rotational
axis application) is desired and the target position should be preset in modulo format.
The translation of a between connected transfer element (e.g. gear) is taken into account via the definition of the range of modulo values (Z118.20– Modulo value).
3.8.2.10 Change of Operating Mode to Positioning
When changing to the Positioning mode, a changeover with speed matching is possible.
To do this, the drive maintains the previous speed for 16 ms (starting from the mode
changeover). Within this time a new positioning task can be started and will then be accepted directly. After the 16 ms have elapsed, the drive is braked to Speed 0 with the preset hold deceleration (Parameter Z121.8– Hold Deceleration).
The speed matching is activated via Parameter Z118.2– Positioning Mode, Bit 0.
3.8.2.11 Halting a Running Positioning Task
A running positioning task can be halted by setting the Halt bit (Control Word Z108.1–,
Bit 8). The data from the current positioning set are used for the deceleration ramp. The
execution of the Halt command is indicated immediately in Positioning Status Z118.1–,
Bit 9. When the set speed = 0 (Positioning Status Z118.1–, Bit 4) and the Speed Zero
message (Z6.2–) is present at the same time, the axis is considered to be halted and Set
Value Reached (Status Word Z108.3–, Bit 10) is set.
When the Halt bit is reset, the remaining travel is automatically completed and the status
bits Set Value Reached (Status Word Z108.3–, Bit 10) and Positioning Status Z118.1–,
Bit 9 are cleared.
The interrupted positioning task can be resumed at the earliest when Set Speed = 0 is
set. If the Halt bit is already set when a start command is set, the positioning task will not
be started. It will only be started when the Halt bit is cleared.

The profile data, including the target position, can also be changed in the Halt state. A
rising edge on the Start bit (Control Word Z108.1–, Bit 4 "New Set Value" or Bit 11 "Start
Positioning") is required for this. However the motion profile cannot be changed.
3.8.2.12 Aborting a Running Positioning Task
A running positioning task can be aborted by setting the Abort bit (Control Word Z108.1–
Bit 12). The data from the current positioning set are used for the deceleration ramp. The
execution of the Abort command is indicated immediately in Positioning Status Z118.1–
Bit 9. The end of the abort process is indicated with the Set Value Reached bit (Status
Word Z108.3– Bit 10).
A new positioning task can be started at the earliest when Set Speed = 0 (Positioning Status Z118.1– Bit 4) is set. The Abort bit must not be set for this.
In contrast to halting a running positioning task using the Halt bit (Control Word Z108.1–
Bit 8), the positioning is not resumed when the Abort bit is cleared!
3.8.2.13 Set Value Profiles
There are two different speed profiles implemented for positioning: Trapezoidal and SCurve.
m With the trapezoidal profile (optimum time), a constant acceleration is assumed; the
change in acceleration is therefore abrupt. In order to attenuate the resulting jerk, it is
possible to smooth the generated profile with a filter element. Any change to the
smoothing - for example due to the activation of a different positioning set - should only
be carried out after a positioning procedure has ended. The action of a change while a
positioning set is running will be prevented by the profile algorithm. This prevents unwanted creeping or overrunning the target.
m With the S-Curve profile (jerk-free), the acceleration is not changed abruptly but rather
follows a trapezoidal shape. The maximum jerk (change in acceleration) can be set.
The positioning time under otherwise equal boundary conditions (same route, same maximum speed and accelerations) is always longer with the S-Curve profile than with the
trapezoidal profile.

3.8.2.15 Control by Means of the "Start Positioning" Method
Positioning control by means of the "Start Positioning" method is described in the following.
This mode can be activated via Z118.2– Positioning Mode Bit 8 = 1.
Sequence of events
The controller has 16 positioning records (1..16) and one active positioning set (0).
At the start of the positioning task, one of the 16 positioning records (1...16) is selected
with Z118.6– Positioning Record Number Actual or a positioning set is transferred e.g.
via a Fieldbus. The positioning task is started with the Start Positioning command (Bit 11
of the Control Word).
The Start bit must always be set to start a positioning task. The positioning task then runs
to the end regardless of the Start bit.
The following differences for this Start bit arise depending on the Positioning Target Mode
parameter (Parameters Z118.10– Target Mode for Positioning Set 0, Z118.19– Target
Mode for Positioning Records 1 to 16):
m With absolute limited target setting (Target Mode = 0, limited to maximum travel amplitude), the Start bit can remain permanently set; positioning is then always based on the
current, absolute target position. This means that when the Start bit is set, only further
new (absolute) target positions need to be written.

Description of the Software Modules and Parameters

m Normal relative target setting, in contrast, depends on the positive edge of the Start bit.
A new target position is generated relative to the old position when the positive edge
of the Start bit occurs.
m On-the-fly relative target setting also depends on the positive edge of the Start bit. A
new target position is generated relative to the instantaneous actual position when the
positive edge of the Start bit occurs.
m With absolute unlimited target setting (Target Mode = 3, not limited to maximum travel
amplitude) positioning is carried out in the direction of the shorter path to the target.
The maximum travel range can be exceeded if the software limit switch function is off.
With the trapezoidal and S-Curve profiles, new positioning data (target position, positioning speed, positioning acceleration, etc.) can also be activated while in motion.
If Positioning Set 0 (Parameters Z118.9– to Z118.16–) is selected in Z118.6– Positioning Record Number Actual, on-line changes must also be made here. The changes take
effect immediately if
m the Start bit is set and
m no positioning error (e.g. hardware limit switches active) is present.
If one of the positioning records 1 to 16 is selected in the current set number, on-line
changes can be made in the selected set. The data from the selected positioning set are
copied completely into Positioning Set 0 and take effect when, in addition to the two conditions above,
m a rising edge on the Start bit has been detected
or
m Z118.6– Positioning Record Number Actual has changed and at the same time
m is activated via Bit 10 "Automatic Start on Change of Positioning Set" in Z118.2– Positioning Mode.
Alternatively, Positioning Set 0 can be written to directly. The basic values of the addressed positioning set then remain unchanged during the on-line changes. Thus only the
speed can be changed at a relative positioning, too. The effective target position remains
unchanged.

Handshake procedure for positioning
Description of the individual points  to :
 Controller writes new positioning data.
 Controller sets "New Set Value" in the control word to identify the data as valid.
 The controller acknowledges the new set values by setting "Set Value Acknowledged"
in the status word. At the same time, the "Target Position Reached" signal in the status
word is cleared. This ensures that the Target Position Reached signal from the previous
positioning task is no longer present for the following sequence. The signal will only be
set again when the newly transmitted positioning procedure has been carried out.
 Controller starts the positioning procedure by setting the "Start Positioning" bit in the
control word. Only after receiving this command will the positioning be started.
 The controller resets the bit for "New Set Value" again. This can also occur before the
start of positioning.
 The controller acknowledges the falling edge of the "New Set Value" control bit by resetting Set Value Acknowledged.
 The controller resets the "Start Positioning" bit again. This can take place during the
still running positioning operation or also only after it has completed.
 As soon as the controller has ended the positioning task and the target has been
reached, it sets the "Target Position Reached" signal.
Time-independent control of the positioning is possible with the aid of the handshake procedure. However it is not absolutely necessary to use the handshake procedure. Positioning data can also be transmitted to the controller without the "New Set Value"
command. These then take effect immediately with the "Start Positioning" command. The
handshake procedure merely makes sure that the "Target Position Reached" signal is
guaranteed to be reset before the "Start Positioning" command is transmitted.

m Bit 6 (Set Value speed limited to maximum speed)
This bit will be set when positioning is started and its maximum set value speed exceeds the specified speed limit (Z121.11–) or the maximum speed mech. (Z107.26–
). It will then be automatically limited to the maximum value to prevent a position error
from developing.
m Bit 8 (transfer of new position data is not possible)
This bit is set when new data can currently not be transferred during an ongoing positioning process. The operation of this bit depends on the driving profile:
Trapezoidal profile:
The transfer of the date is possible here at any time.
S-Curve profile:
Bit 8 will be set when there is a running driving set in the brake phase. The new data
is then not transferred until the brake phase (= "Target position reached" set) is completed.

Remark:
m Bit 0 (Synchronization is set to actual speed with Changeover operating mode)
When the function is activated, it is possible to smoothly switch from another speed or
position controlled operating mode to the position target specification. To do this, the
drive maintains the previous speed for 16 ms (starting from the mode changeover). A
new positioning task may be started during this period of time. Braking to speed 0 will
occur after 16 ms have elapsed with the adjusted stop delay.
Limitation: The bit only applies to the trapezoidal or S-Curve profile.
m Bit 4 (Adjustable response when the new target position is outside of the software end
switch)
This bit can be used to adjust the response during a start of positioning when the new
target position is outside of the software end switch range and this monitoring function
is active.
Bit 4 = 0:
n When the new target position is out of range: Move to next software end switch.
n When current position is already out of range and the new target position is within
range: Move to target position.
n When current position is already out of range and the new target position is out of
range: Move to next software end switch.
Bit 4 = 1:
n When the new target position is out of range: No movement; Error 908 or 909.
n When current position is already out of range and the new target position is within
range: Move to target position.
n When the current position is already out of range and the new target position is out
of range: no movement's; Error 908 or 909.
Errors 908 "Negative Software end switch active" or 909 "Positive software end switch
active" will not result in a pulse block when the standard response is set. They must be
acknowledged before a new drive request start is accepted. A new software end switch
check will occur for each start.
m Bit 5 (Adjustable response when driving in hardware end switch)
This bit is used to adjust whether the drive should trigger a error when a hardware end
switch is reached. The bit is only meaningful when hardware end switch monitoring is
activated.

Bit 5 = 0:
Hardware end switch monitoring will not trigger a error. The drive will brake to speed
0. New drive requests will only be carried out when the direction of travel from the
end switch leads away to the permitted range.
Bit 5 = 1:
When the hardware end switch is overridden, braking to speed 0 will occur and a
error will be triggered. Errors 906 "Negative hardware end switch active" or 907
"Positive hardware end switch active" will not result in a pulse block when the standard response is set. They must be acknowledged before a new drive request start
is accepted. New drive requests will only be carried out when the direction of travel
from the end switch leads away to the permitted range.
m Bit 6 (starting response with controller release for relative positioning)
Bit 6 = 0:
A positive edge will be required in the Start bit after the controller is enabled so that
the values from the positioning set X are transferred to positioning set 0 and relative
positioning will start.
Bit 6 = 1:
If the Start bit is set at the time of controller activation, the data will be transferred
immediately during the controller release and relative positioning will start immediately.
m Bit 7 (homing required)
This bit defines whether the drive will allow positioning prior to successful homing.
Bit 7 = 1:
Error message 900 is set and the drive stops position-controlled at the present position, if the drive was enabled in operating mode Target position mode and homing
wasn't executed prior to that. Positioning tasks are not executed. 
Positioning tasks are executed not until homing was completed successfully
(Z120.1– State bit 1).
m Bit 8 (controlling positioning)
This bit is used to adjust the handshake procedure for positioning.
Bit 8 = 0: Method "New set value" (standard method after CANopen)
Here, Bit 4 "New set value" is used in the control word of the drive manager. The
positioning set data are copied on each rising edge of this bit (Set X to Set 0), adopted internally and the positioning procedure started.
Bit 8 = 1: Method "Start positioning"
Positioning is started with Bit 11 "Start Positioning" of the drive manager control
word. "Change set immediately" ("Set of set values") cannot be used with this method.
m Bit 11 (interpretation of the control word with control through "New set value")
This bit is effective when the method "New set value" (Bit 8 = 0) is set.

with IEC 61800-7-201.
m Bit 12 (Negative directional block) and 13 (Positive directional block)
If one of the two bits is set it will be checked whether the target position to be reached
is located in the blocked direction. If this is the case, a start will not occur and a error
message will be displayed.
If a new target position is to be reached during ongoing positioning, which is located in
the blocked direction, the current target position is started and a error message is displayed.
The block check occurs through a comparison of the old target position to the new target position. The current desired position is meaningless for the test.

CANopen Mode
The target indication occurs in Parameter Z118.16– Relative Target Position and the
differentiation whether this is an absolute or relative target entry occurs through Bit 6
of the Z108.1– control word.
With absolute target entries, a range offset of 231 increments is included in the calculation and the number range is interpreted with applied leading signs.
m Target mode 10:
The indication whether the target is absolute or relative (in relation to the last target) is
determined through Bit 6 of the control word. If Bit 6 is set while the edge of "New Set
Value" is rising, the target specification is relative. If Bit 6 is cleared, the target specification is absolute.
The target is always determined through Parameter Z118.9– Positioning Target Position, and with a relative target entry the value is treated with applied leading signs.
m Target mode 11:
This mode can be applied at axes on which an endless moving (rotational axis application) is desired and the target position should be preset in modulo format. The translation of a between connected transfer element (e.g. gear) is taken into account via the
definition of the range of modulo values (Z118.20– Modulo value).
In this mode the controller calculates the shortest way to the target position itself.
If in the target position a value is entered which is greater or equal than the modulo
value, the error 912 will be output at start and it will be not started.

The counting of the position set values (Z118.3–) and the position actual values
(Z121.9–) occurs furthermore in the „normal“ format.
The conversion of the actual position to the modulo format must occur controller external.
In order to establish the relationship between the normal absolute position format and
the modulo format, either a homing is necessary after switching on the controller or an
absolute encoder must be used whose absolute information is greater than the modulo
position.
Example for target mode 11:
Z118.20– Modulo value = 00140000hex = 20 revolutions
Z118.3– Position set value = 00221111hex in normal absolute format

= 00221111hex mod 00140000hex
= 000E1111hex
First positioning:
Z118.9– Target position = 00063333hex in modulo format
 New absolute target position calculates itself via the shorter way to modulo target
Way to "right" (greater position set values):
WayRight = ModuloValue - SetPpositionModulo + TargetPositionModulo
= 00140000hex - 000E1111hex + 00063333hex = 000C2222hex
Way to "left" (less position set values):
WayLeft = SetPositionModulo - NewTargetPosition
= 000E1111hex - 00063333hex = 0007DDDEhex
 WayLeft < WayRight
 Move left
 New target position in normal absolute format:
TargetPositionAbsolute = SetPositionAbsolute - WayLeft
= 00221111hex - 0007DDDEhex = 001A3333hex
Second positioning:
Z118.9– Target position = 00084444hex in modulo format
WayRight = 00084444hex - 00063333hex = 00021111hex
WayLeft = 00140000hex - 00084444hex + 00063333hex = 0011EEEFhex
 WayLeft > WayRight
 Move right

Operating mode Homing
An in depth knowledge of the absolute position of the drive is generally required to operate positioning drives. If an incremental encoder is used for position actual value recording or if more than one motor revolution is necessary for the actual value recording with
tilt encoder for the entire adjusting range, homing is required. Homing can also be used
to initialize the position actual value recording with absolute value encoders.
Drive guided referencing is addressed below. With drive guided homings, the process
control and movement of the motor is controlled by the drive itself and the reference
switch is thereby activated. This is implemented as a separate operating mode in the
b maXX®.
The homings usually use a switch as a reference mark. For more accuracy, the zero mark
of the encoder is included; however, homings without consideration of the zero mark are
possible.
The zero pulse is used as the zero mark with incremental encoders. The mechanical zero
angle is used with tilt encoders and sine-cosine encoders. The mechanical zero angle
thereby means 0° in the parameter mechanical angle actual value Z106.5–.
Either one of the two end switches (negative or positive hardware end switch) or a separate zero point switch may be used as the reference switch. The type of referencing
(switch, activation direction, etc.) is adjusted through Parameter Z120.4– Reference adjusting mode. The different homing methods thereby correspond with the drive profile of
CANopen.
3.8.3.1 Procedure of a homing under consideration of Zero pulse or Zero angle
A sample procedure of the homing to the negative end switch under consideration of the
zero pulse / zero angle is described below. The procedure of the other homings corresponds with this procedure. There are differences especially in the direction of travel and
sought after switch edge.

Operating Modes
m Phase 1
In Phase 1, Homing speed (Z120.5–) is used until the Reference switch is reached.
The acceleration to reach the homing speed is adjusted with Z120.7– Homing acceleration.
Starting occurs directly with Phase 2 if the switch has already been set during commissioning.
m Phase 2
After the reference switch has been reached, the drive is braked with Z120.8– Homing
deceleration and one eight of the homing speed (however, at least to the homing final
speed) in the reverse direction of travel. It will now be driven out of the switch again.
m Phase 3
The falling switch edge of the switch will trigger braking to the Z120.6– Homing final
speed. As soon as this speed has been reached, the zero mark will be evaluated. The
drive runs with the homing final speed until the zero pulse or zero angle of the encoder
is detected. When the zero pulse or zero angle is recognized, the drive will be stopped
and the home position will be set.
Maximum travel distance can be preset at encoders with zero pulse in this phase. If the
zero pulse is not detected within this distance, "Homing" error no. 901 is reported and
homing is interrupted.
3.8.3.2 Shifting the zero angle
When referencing under consideration of the Zero angle or Zero pulse, it may be near the
switch tolerances of the reference switch. This may result in the detection of two different
home positions with multiple homings that are one revolution apart. The zero angle or
zero pulse is then not always recognized in the same encoder revolution due to the switch
tolerances.
With Incremental encoders with zero pulse the encoder or switch must in this case be
mounted differently so that the zero pulse is no longer near the switch tolerances.
With absolute encoders, the encoder zero angle can be offset using Parameter Z120.10–
encoder offset for internal calculation so that it is outside of the tolerances of the switch.
The measured angle on the reference switch is indicated in Parameter Z120.15– mechanical angle on the Reference switch.
3.8.3.3 Maximum distance for zero pulse detection
A maximum distance can be preset at encoders with zero pulse, which may be moved
after the switching edge until the zero pulse is detected.
If the zero pulse is not detected within this distance, "Homing" error no. 901 homing is
reported and homing is interrupted.
3.8.3.4 Procedure of a Homing to switch only
The zero pulse or zero angle is not evaluated with homings to the switch only. Therefore,
the accuracy depends on the switch tolerances of the switch.

Procedure of homing to negative end switch without zero pulse
m Phase 1
In Phase 1, Homing speed (Z120.5–) is used until the Reference switch is reached.
The acceleration to reach the homing speed is adjusted with Z120.7– Homing acceleration.
m Phase 2
After the reference switch has been reached, the drive is braked with Z120.8– Homing
deceleration and one eight of the homing speed (however, at least to the homing final
speed) in the reverse direction of travel. It will now be driven out of the switch again.
m Phase 3
The falling switch edge of the switch will trigger another reversal of the direction of travel. The drive will now approach the switch again, once again with an eight of the referencing speed.
m Phase 4
Once the reference switch is reached, the drive is decelerated and accelerated in the
reverse direction of travel to the homing final speed, which means the drive will slowly
exit the switch.
m Phase 5
The drive is immediately braked to speed 0 at the falling switch edge of the switch and
the home position is entered.
3.8.3.5 Homing without setting the home position
Setting the home position can also be deactivated for special applications (Z120.2–,
Bit 4). The position target and actual values will then not be changed. Instead, the drive
stops at the home position and the position values can be read out from the control.

3.8.3.6 Automatic setting of the absolute value offset at homing
Applications using absolute encoders, automatically copy the absolute value offset (M0Offset) to the corresponding parameters (Z137.5–, Z137.6–) at the end of homing. Parameter Z120.2– Homing Mode, bit 6 activates this behavior.
The absolute value offset is the shift between the encoder coordinate system (the absolute encoder actual value as read from absolute value encoder) and the position coordinate system redefined by homing (machine coordinate system). This absolute value
offset is considered at initialization of the encoder. This way, a positioning coordinate system occurs, which is the same, as it would be after homing.

Switch wiring
The end and reference switches can be wired as closers or openers. The type of wiring
can be adjusted in the drive using the configuration of the digital inputs. Wiring as an
opener is recommended for safety reasons (detection of wire breaks).
Limit switch
The hardware or software limit switches do not limit the adjusting range during the homings!
The limit switches must be designed so that they cannot be overridden. The option to
leave the switching mode "actuated" with the negative limit switch should only be available in positive direction and only in negative direction with positive limit switch.
Problem during
Homing
If homing is not completed after the reference switch is reached (response through Bit 10
of Z108.3– Status word does not occur), this may be due to the settings for the positioning window (Z121.5–). The drive must be in the positioning window for the period of positioning window time that was set after the home position has been reached. The
positioning window may be adjusted too small so that this requirement cannot be met.
Reproducibility
To reach identical home positions, the following conditions must be met:
m The homing speeds, acceleration, deceleration and encoder offset may not be
changed after the one-time adjustment.
m The homing speed must be reached in Phase 1.

With homing methods 11 to 14, the initial direction of travel is negative unless the reference switch is operated at the beginning of homing. In this case, the direction of travel
depends on the desired switch edge. The direction of travel will be changed at the negative limit switch when the initial direction of travel leads away from the switch.
The home position is one of the zero pulses or zero angles at the rising or falling edge of

This method is not part of the profile conforming homings. The next zero angle (shortest

Homing methods -7 and -8:
These methods reference a mechanical limit position.
With Mode –7 the drive moves clockwise and with –8 counterclockwise toward the mechanical stop.
m Phase 1
Approaching the mechanical stop at the referencing speed. The torque will be limited
at the start of homing to Z120.12– Homing torque limit.
To recognize the mechanical stop, a test will be run to determine whether the drive is
present at the current limit (speed controller status Z18.20– Bit 13 = 1) and, at the
same time, the speed zero message (Z6.2–). The mechanical stop is considered to be
recognized when both conditions have been met through Z120.11– Homing blocking
time.
m Phase 2
If the mechanical stop has been recognized, the home position will be set at this position and the torque limit Z120.12– Homing torque limit will be canceled again.

Operating Modes
Homing methods -9 and -10:
These methods are used to move to a mechanical stop and finally referenced to the encoder zero angle or zero pulse.
With Mode –9 the drive moves clockwise and with –10 counterclockwise toward the mechanical stop.
m Phase 1
Identical with homings –7 and –8
m Phase 2
When the mechanical stop is recognized, the torque limit Z120.12– Homing torque
limit is canceled again and referenced in the reverse direction of travel with Z120.6–
Homing final speed to the encoder zero angle or zero pulse.
During homings to a mechanical stop, specific monitoring procedures may trigger a error
due to the mechanical blocking. This includes the position error monitoring, monitoring of
speed difference and block monitoring.
Activating the Z120.2– Mode Bit 5 will prompt the controller to deactivate the three monitoring procedures for the period of homing, which means from the start of homing to the
recognition of the mechanical stop after expiration of the Z120.11– Homing blocking
time.
CAUTION!
1
The controller cannot distinguish with homing methods –7, -8, -9 and –10 whether
the block is caused by the mechanical stop or otherwise! In the second case, the
drive is incorrectly referenced!
2
The machine may be damaged with homing methods against mechanical stops.
The user must prevent this through a sufficiently low setting of the homing speed
(Z120.5–) and the maximum drive torque during homing (Z120.12–).
3.8.3.19 Command set home position
Besides the homing it is possible to set the reference point in the inhibited state (pulse
inhibit). By writing the command "Set reference point" to the parameter Z120.17– the set
value of the reference point is taken over at the current position.
The drive acknowledges the setting of the reference point by setting the bit 2 in the parameter Homing status Z120.1–. By writing the command value 0 the bit 2 in the homing
status is reset again.
However the command is possible in the inhibited state only independent of the current
operation mode of the drive.

Bit 4: Referencing with or without setting the home position
By default, the position actual values and set values are set to the home position after the
home position is reached. For some applications, especially with multiturn absolute value
encoders it may be purposeful to determine the position actual value of the encoder at the
home position to take it into consideration automatically in a control.
Setting the home position can therefore be deactivated accordingly. The drive will complete the homing; however, the position values are not set to the adjusted home position
but will remain unchanged. The control can now read out the position actual value at the
home position.
Bit 5: Deactivate monitoring with homings to mechanical stop
During homings to a mechanical stop, specific monitoring procedures may be triggered
due to the mechanical blocking. This includes the position error monitoring, monitoring of
speed difference and block monitoring.
Three options are available to solve this problem:
– The user will adjust active monitoring suitable for homing. However, this may be too
weak for "normal operation".
– The user will deactivate monitoring for the duration of homing itself.
– Activating the Mode Bit 5 will prompt the controller to deactivate the three monitoring
procedures for the period of homing, which means from the start of the homing to
the recognition of the mechanical stop after expiration of the Z121.11– Homing
blocking time.
Bit 6: Automatic setting of the absolute value offset (M0 offset)
The parameters of the absolute value offset are set at the end of homing after bit 6 was
set. The absolute value offset is automatically saved in the encoder, if the parameter
Z137.3– Encoder Data Selection is set, so that the absolute value offset is read from the
encoder during initialization.
120.3
Home position
The home position is the position value that indicates the absolute position of the drive at
the home position. This value must be adjusted prior to the reference run. If the drive has
reached the home position after the reference run, the current position set value and position actual value will be wet to the home position value.
120.4
Homing method
Selection of the homing method.
This parameter determines the procedure for the reference run. This includes the start direction of the home position and evaluation of the reference initiator.

the zero angle is also referenced with an incremental encoder.
Remarks:
m The reference run modes -5 to -1 still exist for reasons of compatibility. They correspond with the applicable indicated modes.
m The modes 1 to 14 use the zero pulse or zero angle as an additional signal. Zero angle
refers to the encoder zero angle, which means 0° in the encoder angle.
m The modes 17 to 30 correspond with modes 1 to 14 in principle, only that no zero angle
or zero pulse is used. Referencing in these modes only refers to the switch.

Manual drive operation
The Manual drive operation, also known as Tipping operation, serves to manually move
the drive. This is a position controlled operating mode.
The drive can also be moved without specification of a position set value with simple operation of the buttons "Forward" or "Back" (Z108.1– Control word Bit 11 and 12). This
serves to set up a machine or determine the position set values that are needed later.
The manual drive operation is set through the Z109.1– operating mode = 5.
The main functions in manual drive operation are:
m Separately adjustable acceleration for start and reverse.
m Selection between two speed profiles 
"Trapezoidal" (block shaped acceleration) 
"S-Curve" (trapezoidal acceleration)
m Online change (OPERATION ENABLED) of the profile data is possible at any time,
which means the tipping speed and acceleration can be changed while the drive is
moving.
m Evaluation of the software limit switches and hardware limit switches (activation, refer
to Z121.1–)
m Optional speed actual value synchronization with activation of manual drive operation.
m Use of the Z121.7– feed rate override.
m Bipolar limiting of output speed through Parameter Z121.11–.

Operation mode spindle positioning (M19 command)
With activating of Z109.1– Operation Mode Set = -6 (spindle positioning) the drive switches to position control (if not yet active), synchronizes thereby with the actual speed set
value and begins to slow down to Z149.4– Spindle positioning speed. If this speed is
reached the drive positions to Z149.3– Spindle angle position considering Z149.2–
Mode.
The message „in position“ will be set from the drive in Z149.1– when
– the position set value reaches Z149.10– Active target position
and
– the position actual value is located in the Z121.5– Positioning window in the
Z121.6– Positioning window time.
The message „in position“ is also available in bit 10 of Z108.3– Status word 1.

A sequential positioning is a positioning after the first spindle positioning. The controller
is in operating mode spindle positioning.
Due to start a sequential positioning the bit 11 in Z108.1– Control word 1 must be set, i.e.
a positive edge is needed in this control bit. A running positioning must first be completed,
before a new positioning can be started. The controller acknowledges an identified and
accepted start command by setting bit 12 "Start-Command-Acknowledge" in Z108.3–

Types of sequential positioning
The setting, whether a sequential positioning shall occur "absolute/relative", will be set in
Z149.2– Mode bit 4.
Bit 4 = 0: Absolute sequential positioning
Bit 4 = 1: Relative sequential positioning
Absolute positioning using Z149.3– Spindle angle position
Only the Low-Word of the spindle angle position is copied in the Low-Word of the effective
target position. The High-Word is not used at the time.
In order to start an absolute sequential positioning the control bit 11 must be set (positive
edge). The positioning direction is determined with bit 0 and 1 of the Z149.2– Mode.
00: Towards greater position set values
01: Towards smaller position set values
10: Shortest distance
11: Reserved (value is incorrect and is not accepted)
Relative positioning using Z149.9– Spindle relative offset
Dependent on the preset direction the new target position is calculated from the last target
position plus or minus spindle relative offset. Only the Low-Word is used from Z149.9–.
A positive edge in the control bit 11 is necessary in order to start.
The positioning direction is determined only with bit 0 of the Z149.2– Mode.
0: Towards greater position set values:
1: Towards smaller position set values
NOTE!
The value of bit 4 (sequential positioning absolute/relative) in Z149.2– Mode is irrelevant at switching in the operating mode spindle positioning. At the first spindle positioning it will be positioned always absolute to the spindle angle position! The actual
direction of revolution remains thereby. A reversion is not possible.
If the motor is in standstill (standstill message is existent) at switching, bit 0 and 1 of
Z149.2– decide on the positioning direction.

Spindle positioning speed
If operating mode spindle positioning is activated, either the drive brakes up to the spindle
positioning speed or the drive keeps the preset speed. If operating mode spindle positioning is switched on from standstill, the drive accelerates with maximum acceleration to the
spindle positioning speed.
The internal resolution of the spindle positioning speed is 0.0625 Inc/ms. Therefore only
parameter values in multiples of the resolution make sense. Interim values will be rounded down.

Operating Modes
3.8.6
Position control with synchronous set value specification
The cyclic synchronous position set value specification is activated through operating
mode Z109.1– = -4. In this operating mode, the position set value that is transferred in
every fieldbus cycle is interpolated in the control cycle. The interpolated set value is the
position set value for the position control.
The major functions are:
m Interpolation of the fieldbus set value for the cycle of the position control.
m Selection between two input channels for the position set value to be interpolated:
– Z136.3– Set value in the format 16 bit revolutions and 16 bit angle
– Z136.5– Set value in the format 32 bit angle
m Each of the two input channels to one offset input additionally:
– Z136.4– Position offset in the format 16 bit revolutions and 16 bit angle
– Z136.6– Angle offset in the format 32 bit angle
m Additional input as offset speed Z136.7–. The function can thereby be tested without
cyclical set value specifications through the fieldbus.
m Optional speed actual value synchronization when activating the operating mode.
m Optional extrapolation during set value failure.
m Evaluation of software limit switches possible  Activation, refer to Z121.1–.
m Evaluation of hardware limit switches possible  Activation, refer to Z121.1–.
m Stop possible through control word Bit 8 of the drive manager.
m Set values can be blocked through the control word Bit 11 of the drive manager.
m Display of current output set values: Acceleration, speed and position.
m Bipolar limiting of output speed through Parameter Z121.11–.
m The set fieldbus cycle time Z131.18– is used as the interpolation interval.
m The interpolation interval can be extended through the factor in Parameter Z136.2–
Mode in Bit 12 and 13. The following applies: 
Interpolation interval = Factor * Fieldbus cycle. 
Factors 1, 2, 4 and 8 are possible.
m PT1 filter for smoothing the transferred position set value
m An external, cyclical specification of the speed and acceleration feedforward values
takes place. For details see Z111.7–, Z111.8– and Z18.9–.
NOTE!
Currently, the fastest adjustable set value cycle (= Fieldbus cycle) for this operating
mode is 250 µs and thereby corresponds with the default setting for the cycle of the
position control. Especially with cycle rates of less than 1 ms, the computation time
capacity utilization of the controller must be observed when using a double axis unit!

With setting of bit 5 the error message and error response can be switched off. In this
case only the set stop (bit 4 = 1) is executed and the drive direction is inhibited.

Operating Modes
m "no response" and Bit 4 = 0: 
Only the corresponding error is settled. New set values through the fieldbus continue
to be accepted. The control must perform the corresponding response.
m "no response" and Bit 4 = 1:
In addition to settling the error, a Stop is also triggered. Braking occurs drive internally
with Z121.8– Stop delay. New set values through the fieldbus will be ignored. 
After ending the Stop (speed set value = 0), the end switch errors may be confirmed.
During confirmation, the drive control synchronizes the input parameters Z136.3– Target position and Z136.5– Target angle with the current Z136.8– Output position set
value. The higher level control must perform this as well and can then be assigned new
set values.
Bit 8: Interpolation procedure
This is where the procedure for the interpolation level "Set value cycle  Cycle internal
set value interface" is entered.
The interpolation level "Cycle internal set value interface  Controller cycle" is thereby
not influenced. This interpolation is defined through Parameter Z111.6– Interpolation
mode!
The cycle of the internal set value interface corresponds with the fieldbus cycle time entered in Z131.18–. The set value cycle can be increased through the factor for the interpolation interval against the fieldbus cycle time. If the factor for the interpolation interval
(Z136.2– Bit 12 and 13) is set to 1, the interpolation level "Set value cycle  Cycle internal set value interface" is not needed and Bit 8 is of no importance.
Bits 12 and 13: Factor for interpolation interval
These two bits can be used to enter an increase of the cycle time of the new set values
compared to the fieldbus cycle time Z131.18–. The cycle time of the new set values corresponds with the displayed effective interpolation interval (Z136.11–)
Effective interpolation interval = Factor * Fieldbus cycle time
At active interpolation (factor IP interval > 1) and simultaneous using of parameter
Z136.5– as input a deviation can occur between the 32 bit input angle (Z136.5–) and the
32 bit output angle (Z136.12–) at fixed input set value. This difference is caused by the
interpolation and is internally saved and is considered in the input set value with the next
motion.
Example 1:
New set values are to be transferred under the following conditions:
n New set values are transferred during each fieldbus cycle: 
The setting of the interpolation procedure is therefore irrelevant  Bit 8 = 0
Factor for IP interval = 1  Bit 13 = 0 and Bit 12 = 0
n The hardware and software limit switches should only report errors  Bit 4 = 0
n The set values have the format 32 Bit angle
Input channel is thereby Z136.5– target angle  Bit 2 = 1
n The extrapolation with set value failure should be effective  Bit 1 = 1
n The synchronization at activation of the operating mode must be active  Bit 0 = 1
 Z136.2– Mode = 0007hex

 Z136.2– Mode = 1102hex
136.3
Target position
The parameter is a set value input for the position control with cyclical synchronous position set value specification (Operating mode -4). It is a position value in format 16 Bit revolution and 16 Bit angle.
This input is selected using Parameter Z136.2– Mode Bit 2 = 0.
The default setting for the cycle time for new set values is the fieldbus cycle time
(Z131.18–). The specified position set value is then interpolated by the cycle time of the
cycle time of the set values to the control cycle.
136.4
Position offset
The parameter only acts as an offset when the input Z136.3– Target position has been
selected.
The offset value is added to the target position. This is an absolute position value and it
is also set regardless of the number of communication transmissions and always as an
absolute offset value for the target position. This means that if, for example, the same offset value is set twice through communication it will not be added twice.
If the offset is not 0, then Z136.3– Target position and Z136.8– Output position set value
will deviate from each other by the offset value. When the offset is reset to 0, the output
position set value will correspond with the target position.
The format of the parameter is 16 Bit revolution and 16 Bit angle. However, in contrast to
Parameter Z136.3– it has applied leading signs!

Target angle
The parameter is a set value input for the position control with cyclical synchronous position set value specification (Operating mode -4). It is a position value in the format 32 Bit
angle.
This input is selected using Parameter Z136.2– Mode Bit 2 = 1.
The default setting for the cycle time for new set values is the fieldbus cycle time
(Z131.18–). The specified angle set value is then interpolated by the cycle time of the cycle time of the set values to the control cycle.
136.6
Angle offset
The parameter only acts as an offset when the input Z136.5– Target angle has been selected.
The offset value is added to the target angle. This is an absolute position value and it is
also set regardless of the number of communication transmissions and always as an absolute offset value for the target angle. This means that if, for example, the same offset
value is set twice through communication the value will not be added twice.
If the offset is not 0, then Z136.5– Target angle and Z136.12– Output angle set value will
deviate from each other by the offset value. When the offset is reset to 0, the output angle
set value will correspond with the target angle.
The format of the parameter is 32 Bit angle. However, in contrast to Parameter Z136.5–
Target angle it has applied leading signs!
136.7
Offset speed
The parameter acts as offset speed when the position control is active with cyclical synchronous position set value specification (Operating mode -4). Regardless of the set value input setting (Z136.3– or Z136.5–) it is always active and in format 16 Bit angle.
Its value is added to the interpolated set value as Delta position (= speed) during each
cycle of the set value interface.
When using the offset speed it must be observed that the input set value and position set
value (Z111.2– Position set value revolutions and Z111.3– Position set value angle)
must no longer match.
The parameter must be distinguished from the speed additional set value, which has a
direct effect on the speed control input!
136.8

This parameter shows the calculated target position after offset addition and is updated

Smoothing time position set value
In this parameter the time constant of the PT1 filter for smoothing the transferred position
set value is set in the operating mode "Position control with synchronous set of setpoints".
The PT1 element is calculated after Parameter Z121.11– Speed limit, i.e. the already interpolated and limited position set value delta is smoothed.

m With the transfer in the "operation enable" state the change of smoothing time is
activated, i.e. not until pulse inhibit and a re-enabling.
m Depending on Parameter Z136.13– the output set value reaches the input set value delayed, due to the PT1 element. The implemented PT1 algorithm prevents a
constant deviation at a constant input set value. However, another time delay is
provided by the clearing mechanism until the input value is reached. A completed
transient is visible at bit 4 speed set value = 0 of parameter Z136.1– Status.

Output speed set value 32 bit
This parameter shows the generated output speed set value after offset addition and after

Operating mode synchronous operation
The software module synchronous operation moves a slave axis in a synchronous angle
to a master axis.
A virtual master axis is calculated in the drive. The speed-set value must be specified.
The set value of the master axis serves as the input value for the electronic transmission.
The output value of the transmission is the position set value for the position control.
The following synchronous operation modes (Z145.2– Mode; Bit 0 to 3) are differentiated:
m Bit 0-3 = 0010: Virtual master axis in relative synchronized angle
The set value for the slave axis is specified in this mode through Parameter Z145.10–
Virt. lead speed set value. The axis is located in the position control.
A position set value for the virtual master axis is calculated in the drive from the speed
set value. The drive follows this virtual master axis synchronized.
This mechanism is purposeful when other axis are connected as slave axis. These
slave axis then receive the set value of the virtual master axis as input set value. Subsequently, all other axis then follow the same set value including the axis that calculates the virtual master axis itself.
The input set value of the virtual master axis can be routed through a ramp generator
(ramp function generator) or have a direct effect. Refer to the related explanations of
Bit 12 of the mode.
Electronic transmission
The electronic transmission extends the functionality of the software module synchronous
operation with an adjustable transmission ratio between slave axis and master axis. The
transmission ratio i is specified from 2147483647:1 to 1: 2147483647 as quotient from
two natural numbers and can also be changed in the released status ("Online"). The
counter may become negative. The function of a reverse transmission can thereby be implemented.
The transmission factor settings are entered in the parameters Z145.3– Transmission
revolutions slave axis and Z145.4– Transmission revolutions master axis.
An editing mode can be selected through Z145.2– Mode Bit 4. The two transmission factors can be changed without changing the transmission ratio. The two factors will become
effective simultaneously when the Bit 4 (1  0) is deleted.
Speed - synchronous operation
A Speed - synchronous operation can be implemented by switching off the reinforcement
of the position control circuit (Z18.14– Kv Position control = 0). The speed feedforward
(Z18.15– w2 Feedforward factor = 1.00) must be set to 100% when the calculated slave
axis set value speed is to be transferred to the speed control 1:1. The speed feedforward
can be changed for corrections of the slave axis speed.
The smoothing of the speed feedforward Z18.70– can be used for smoothing the speed
set value of the master axis.

Operating Modes
Other functions:
m Optional speed synchronization of the slave axis with the master axis is possible when
the synchronous operation is activated. For details, refer to Parameter Z145.2– Mode
Bit 8.
m Speed synchronization with Online operating mode changeover (Status Operation Enabled) from synchronous operation to another position or speed controlled operating
mode. The speed synchronization must be activated for the operating mode.
m Stop command possible through control word Bit 8. A speed synchronization with the
master speed may occur after the Stop has been canceled.
m Integrated Ramp generator with profile data in master axis resolution. The setting is entered in Parameters Z145.7– to Z145.9–. A selection between speed profiles Trapezoidal or S-Curve is possible. The ramp generator becomes active during speed
synchronization, with a Stop command or with the virtual master axis.
m Virtual master axis without ramp generator (ramp function generator) with optional interpolation of set value cycle to control cycle. This mode is activated in Parameter
Z145.2– Mode Bit 12 = 1.
The interpolation cycle setting for the set value speed (Z145.10– Virt. lead speed set
value) is entered in Z145.11–. Interpolation does not occur with a value of 1 ms and
the Z145.10– is directly (not interpolated) transferred to the transmission input). The
parameter may also be a multiple of the fieldbus cycle, such as fieldbus cycle = 2 ms
and set value cycle = 6 ms. In the example this means that the control must only send
a newly calculated speed set value to the controller every third fieldbus cycle.
m Monitoring of speed synchronization between master and slave axis. 
Z145.1– Status Bit 8 displays exiting the Z145.6– Synchronization velocity window of
the slave axis.
m There are two additional inputs (Z145.15– and Z145.16–) besides the main set value
Z145.10– or the master axis position, if the master axis is virtual or real.

Operating Modes
A position set value for the virtual master axis is calculated in the drive from the speed
set value. The drive follows this virtual master axis synchronized.
This mechanism is purposeful when other axis are connected as slave axis. These
slave axis then receive the set value of the virtual master axis as input set value. Subsequently, all other axes then follow the same set value including the axis that calculates the virtual master axis itself.
The input set value of the virtual master axis can be routed through a ramp generator
(ramp function generator) or have a direct effect. Refer to the related explanations of
Bit 12 of the mode.
m Bit 8: Activate speed synchronization on master axis
This bit activates the speed synchronization for the speed set value of the master axis
when activating the operating mode synchronous operation or following a Stop command through the control word (Z108.1– Bit 8 = 1)
Procedure of synchronization after activation:
– Automatic activation of the internal ramp generator using Parameters Z145.7– to
Z145.9–.
– The speed set value of the master axis defines the target speed for the ramp generator.
– The speed actual value of the slave axis, under consideration of the inverse transmission factor, corresponds with the start speed for the ramp generator. This enables the activation of a moved slave axis on the fly.
– Synchronicity is considered to be established when the slave axis enters the
Z145.6– Synchronization velocity window for the first time around the speed set value of the master axis. From this point, the controller will independently switch from
the internal ramp generator to the set value of the master axis.
– If the master axis changes its speed during synchronization in progress, the target
speed for the ramp generator will be adjusted accordingly.
If the new target speed slows down, braking occurs with a deceleration value Z145.8–
to the new value.
In the case of the S-curve, the current acceleration value must first be reduced through
the jerk value setting Z145.9–, which means the speed will first be increased further.
Procedure with Stop through the control word and subsequent synchronization after
canceling the Stop:
– The Stop command is requested through the Z108.1– Control word Bit 8 = 1.
– Automatic activation of the internal ramp generator using Parameters Z145.7– to
Z145.9–. Disconnect the slave axis from the main axis set value.
– The target speed for the ramp generator is set to 0.
– The speed actual value of the slave axis, under consideration of the inverse transmission factor, corresponds with the start speed for the ramp generator.
– The Stop cannot be ended until the speed set value at the output of the ramp generator has reached 0.
– The stop is canceled by deleting the control word Bit 8.
– After canceling the Stop, the target speed of the ramp generator is set to the current
speed set value of the master axis.

– Synchronicity is considered to be established when the slave axis enters the
Z145.6– Synchronization velocity window for the first time around the speed set value of the master axis. From this point, the controller will independently switch from
the internal ramp generator to the set value of the master axis.
– If the master axis changes its speed during synchronization in progress, the target
speed for the ramp generator will be adjusted accordingly.
If the new target speed slows down, braking occurs with a deceleration value Z145.8–

In the case of the S-curve, the current acceleration value must first be reduced through
the jerk value setting Z145.9–, which means the speed will first be increased further.
NOTE!
With deactivated speed synchronization (Bit 8 = 0) the slave axis may not be added
to a moving master axis and a stop may not be ended. Because the master axis set
value is transferred immediately, an undesired fast acceleration may occur depending on the master speed. This may lead to damage to the mechanism and trigger a
error when position error monitoring is active.
m Bit 9: Speed profile of the ramp generator
This bit is used to set the speed profile for the ramp generator. The ramp generator is
active with the virtual master axis and speed synchronization processes.
m Bit 12: Virtual master axis - Handling the speed set value of the virtual master
axis
If Bit 12 is set to 0, the value in Parameter Z145.10– Speed set value is routed through
the ramp generator of the synchronous operation to the transmission input. Parameters Z145.7– to Z145.9– apply as profile data. The profile type is set in the Z145.2–
Mode Bit 9.
If Bit 12 is set, the speed set value is immediately routed to the transmission input without ramp generator. Optionally, an interpolation can also be activated for the speed set
value. When the interpolation is active, the result will be a set value at the transmission
input that is delayed by an interpolation interval of - 1 ms.
The interpolation interval setting is entered in Z145.11– Virt. lead set value cycle.

Speed limit master axis
Display of maximum editable speed (= Position Change) at the transmission input (master axis) to prevent overrun at the transmission output (slave axis). The value is calculated
based on the current transmission factors.
If the set value of the master axis exceeds this value, a error will be issued and the subsequent drive will be blocked. Monitoring may occur with an incorrect setting of the transmission factor or a faulty set value of the master axis. Normally, these high speeds cannot
occur.
The maximum possible value (= 2147483647 Inc/Tab) is displayed at the transmission input for |Z145.3– Rot. Slave axis| < Z145.4– Rot. master axis.
The sampling time Tab in the unit of Parameter Z145.5– corresponds with the effective
position controller cycle (refer to Z1.8– RT0 cycle time).
Example:
Position controller cycle = 250 µs  Inc/Tab = Inc/250µs
Z145.3– revolution of the slave axis = -55555
Z145.4– revolution of the master axis = 1000

Synchronization velocity window
This parameter is used to set the monitoring window for the speed synchronicity. The
Synchronization velocity window is symmetrically arranged around the speed set value of
the master axis.
If the speed actual value of the slave drive is outside of this window under consideration
of the electric transmission, Bit 9 "Slave axis outside of synchronization velocity window"
will be set in the Z145.1– Status. If the speed actual value of the slave axis enters the

Monitoring is not activated until speed synchronization is completed (Z145.1– Status

Synchronization acceleration
The maximum acceleration is set in the operating mode synchronous operation. The parameter determines the permitted acceleration on the master axis ("in front of the transmission"). It is used as soon as the internal ramp generator for the synchronous operation
is activated. This is the case with speed synchronization, a Stop command or the virtual
master axis.
145.8
Synchronization deceleration
The maximum deceleration is set in the operating mode synchronous operation. The parameter determines the permitted deceleration on the master axis ("in front of the transmission"). It is used as soon as the internal ramp generator for the synchronous operation

master axis.
145.9
Synchronization maximum jerk
This parameter is used to set the maximum jerk (change of acceleration) in the Synchronous operating mode. The parameter determines the maximum permitted jerk value on
the master axis ("in front of the transmission"). It is used as soon as the internal ramp generator for the synchronous operation is activated. The parameter is only effective when
the S-curve (Z145.2– Mode Bit 9 = 1) is set as the speed profile.
Example:
Z145.9– Synchronization max. jerk = 0.1025 Inc/ms³
Z145.7– Synchronization acceleration = 1.3450 Inc/ms²
Time after which the acceleration is reached:
1,3450 Inc/ms²
t = ------------------------------------ = 13,1 ms

Virtual master speed set value
This parameter is the set value input for the function "virtual master axis". It specifies the
set value speed on the master axis ("in front of the transmission").
The "virtual master axis" is activated through Parameter Z145.2– Mode Bit 0-3 = 0010.
145.11
Virt. master set value cycle time
This parameter is only effective in the function "virtual master axis". Changes in the parameter only become effective when the controller is blocked.
The interpolation cycle setting for the set value speed (Z145.10– Virt. master speed set
value) is entered here. Bit 12 must also be set in Parameter Z145.2– Mode.
Interpolation does not occur with a value of 1 ms and the Z145.10– is directly (not interpolated) transferred to the transmission input).
The parameter may also be a multiple of the fieldbus cycle, such as Fieldbus cycle = 2 ms
and set value cycle = 6 ms. In the example this means that the control must only send a
newly calculated speed set value to the controller every third fieldbus cycle.
145.12
Master speed
This parameter indicates the effective set value speed in front of the transmission.
In the case of the actual master axis, the current speed of the master axis encoder will be
shown. This also applies to a Stop or speed synchronization, although the set value of the
ramp generator affects the transmission input here.
In the case of the virtual master axis, the set value speed at the output of the ramp generator or interpolated set value speed will be displayed.
145.13
Master position revolutions
The parameter shows the number of revolutions in the position set value of the master
axis ("in front of the transmission").
In the case of the actual master axis, the actual value of the master axis encoder will be
shown. The parameter will only be updated in the "Operation enabled" status.
In the event of the virtual master axis, the value is included through integration of the set
value speed and may be set to a blocked status.
145.14
Master position angle
The parameter shows the angle of the position set value of the master axis ("in front of
the transmission") in 32 bit resolution.

In the case of the actual master axis, the actual value of the master axis encoder will be
shown. The parameter will only be updated in the "Operation enabled" status.
In the event of the virtual master axis, the value is included through integration of the set
value speed and may be set to a blocked status.
145.15
Master speed set value additive 1
145.16
Master speed set value additive 2
These parameters are two additional set value inputs. The resolution is
10000 * 16 bit increments/revolution per ms.
The sum of both additional speeds (ms) is added to the internally effective master axis
position as a change of position at the function "Real master axis". The displayed master
axis position in Z145.13– and Z145.14– continues to show the original master axis value.
At the "Virtual master axis" function the values are added to the main set value Z145.10–
prior to the set value interpolation and the ramp function generator.
For the "Virtual master axis with interpolation" mode the main set value must be written,
e.g. as a cyclical set value via the fieldbus. Only if this is done the interpolation will be
started and the total set value from the three input parameters will be used.
It is not necessary to write the main set value for mode "Virtual master axis with ramp generator". Each cycle calculates the total set value. This value is written to the input of the
ramp generator.
145.18
Master angle offset
The set value of the slave axis can be set in the "Real master axis" mode with this parameter. The offset immediately is active.
Set value slave axis = Master axis position + Angle of master axis offset
The offset operates as an absolute position set value. This means, if the same offset value is set twice, the value is not added twice. The change of the offset is always added. If
the offset is set to zero, the set value of the slave axis corresponds to set value of the
master axis.
The offset is a signed value in a 32 bit angle format. It has the resolution of the master
axis, is previously added to the gear and its sampling rate is 1 ms.
The resulting offset adjustment speed can be limited via Z145.10– Virtual master set
speed value. Therewith the entire offset adjustment can be distributed to several controller cycles.
The parameter has no function at synchronous operation with a virtual master axis.

Operating mode Notch position search
The operating mode Reference notch position is used to determine the installation position (notch angle) of the encoder with synchronous machines.
For Baumüller motors with absolute value encoder and electronic type plate the notch angle is stored in the electronic type plate and therefore does not have to be determined.
For motors with absolute value encoder without electronic type plate the notch angle is
determined once and stored in the EEPROM of the controller.
For motors with relative encoder system the notch angle search must occur after each
commissioning and activation of the motor bearing encoder!
x
DANGER!
A motor that is operated with an incorrect notch position can move unintentional with maximum power!
Dangerous movings can be caused from faulty triggering of connected motors. Causes could be:
n Incorrect or faulty wiring or cabling
n Error at the operation of the components
n Incorrect input of parameters before commissioning
n Error at the sensor or signal encoder
n Defective components
n Error in the software
This error can appear immediately after switch on or after an undefined time period
during operation.
Therefore:
m Activate position error speed monitoring. This monitoring reliably avoids an uncontrolled running of the motor.
Three methods are available to determine the notch position (refer to Z127.1–).
A current set value is specified at the methods 0 and 1 by the controller. This set value is
limited to the set value, which was preset in parameter Z127.4–.
m Method 0
The motor must be movable by one pole pair in both directions in order to use this
method. This method is suitable for the dismounted motor, which is free of load.
During this procedure the Current set value is linearly (Z127.5– Rate of current rise)
increased to the Z127.4– Maximum current. The motor engages into a position, which
is shifted by a half pole pitch. The notch position is calculated from the relevant encoder
angle.
The determination of the notch position is made twice. Both results must be checked
for consistency. If both of the notch positions deviate by more than 22.5°, a third pole
position search must be completed. This result must be compared with the result of the
2nd calculation. If the deviation of both notch positions is out of tolerance, the error No.
716 is generated..

Operating Modes
m Method 1
The motor must be able to move free of load in any direction with at least twice the value of Z127.9– Maximum angle. Reducing Z127.9– to values lower than 0.5° does not
result in a pole position search without motion. This is achieved with method 2.
The current set value is linearly (Z127.5– Current rise) increased to the Z127.4– Maximum current. The movement of the motor is minimized by adjusting the electric angle
(Z127.10– Angle rising) during this operation. Based on the starting position the mechanical movement is monitored via Z127.13–.
The determination of the notch position is made twice. Both results must be checked
for consistency. If both of the notch positions deviate, a third pole position search must
be done.
Reasons for error 716:
– No conformant notch positions after making three procedures of measuring.
– No conformance check, because of less than two successful measuring.
– The mechanical movement during the procedure is greater than the value of
Z127.11– Error limit mechanical angle change.
– Timeout of 2 minutes for pole position search was exceeded.
Method 1 affects the following factors:
– Notch positions of motor.
– Friction.
– Resolution and quality of encoder signals.
– Setting of current controller see ZAutotuning of Current controller– from page
155.
– Setting of specific parameters for the operating mode Notch position search.
The default values of these parameters (Z127.5– to Z127.12–) are preset robust enough for the most drive configurations. Therefore, in general, the default
values must not be changed.

Notch position search with the injection method
This method is used for applications, where the motor shall not move or shall only move
a bit. However this method can be not used with all motors, as for example with ironless
motors.
The notch position search takes place in two steps:
m The motor is applied with high-frequency voltage, which also causes a clearly audible
noise. The electrical angle is searched via the tracking controller. The voltages and frequencies are set via the parameters Z133.3–, Z133.4–, Z133.6– and Z133.7–.
m In the second step, the notch angle, which was found, is checked if it 180° next to it or
if it is not. The ratio from the 2nd harmonic to the fundamental frequency is checked for
this.
3.8.9.1 Parameter survey and parameter description
Besides the notch position search method 2 (injection method), the parameters are additionally used for the sensorless control of the synchronous machines. Therefore, they are
shown in the ZParameter overview– from page 570 and are described under
ZDescription of the Parameters– from page 571.

Operating Modes
3.8.10 Sensorless control for synchronous machines
NOTICE!
The motor can make unintentional movements at faulty parameterization, because
there is no encoder available.
The drive controller b maXX 3300 makes the operation of a synchronous machine in the
speed control (operation mode "speed control") without rotary encoder or position encoder (sensorless encoder) possible. A position-controlled operation (operating modes position control, synchronous operation, positioning), is not implemented at the moment.
The sensorless control procedure accepts the measured currents and the specified voltage set values from the current controller. On this basis, it calculates the electrical angle
and the motor speed. This calculation is the basis of the voltage model of the synchronous motor. The motor data must be exactly known for this or must be determined with
the help of the self-optimization, in order to do this.
In the range of low speed or of standstill or if the voltage is too low or even zero, which
was induced in the motor, the voltage model is expanded by the injection procedure or it
is replaced by the controlled procedure. The use of the magnetic anisotropy of the machine or the difference between the direct axis and of the cross-current axis is the basis
of the injection procedure (Ld and Lq). This is caused by the iron saturation due to the
field of permanent magnets. The orientation of this anisotropy is analyzed with the help
of high-frequent (HF) injection. The HF-voltage signal is injected in the motor, the HF-current is filtered, and it is demodulated according to a certain algorithm and is routed to a
specific tracking controller. It controls the orientation of the d-axis or the electrical angle
in such a way, that the estimated d-axis aligns to the physical axis of the permanent magnet field.
A constant current is set in Id-direction at controlled operation. The rotor adjusts itself to
the load and splits the constant current in a torque current and a reactive current. This
partition is estimated via a special procedure. At the transition to the voltage model this
information is assumed in form of a electric angle shift, so that a jerk-free transition to the
voltage model is possible.
The constant current at controlled operation can be set in Z133.22–. The constant current can be increased to maximum current at speed set value unequal 0 via bit 4 of
Z133.1–. The ramp-up time in the ramp function generator must be parameterized so
that the motor can follow the acceleration ramp. In order to improve the transition to the
voltage model, it is recommended to switch off the consideration of the dLi/dt terms (bit 8
of Z133.1–).
NOTICE!
If there is a faulty parameterization, it cannot be guaranteed, that the motor reaches
the desired speed!
On principle the dead time compensation should be used at the sensorless control, so
that the non-linearity of the power unit can be compensated, in order to improve the exactness of the voltage model. However the dead time compensation can affect the injection procedure. This must be tested in each case.

The torque display requires an exact dead time compensation at low speeds in the controlled operation. In order to improve the accuracy of the torque, a fine adjustment of the
dead time compensation can be carried out at speed 0 via bit 9 of parameter Z133.1–.
3.8.10.1 General constraints of sensorless control with the injection procedure
The injection procedure for the sensorless control of the SM can only be operated, if
m the energy transducer possesses an iron-core magnetic with pronounced saturation effects (it cannot be used on rotating and linearly ironless machines) and
m the magnetic symmetry of the three phases is existent
Because of the constraints, which are listed above, the operation of sensorless control of
the SM, as well as the use of method 2 of notch position search is only then possible, if
the machines have been tested successfully.
Constraints of the sensorless control at very low speed
The operation is also possible at very low speed and at standstill. Because of the higher
torque ripple, however, the motor may run irregularly.
Switch on / Enable at rotating machine
At first there is no speed or position information available, when enabling the drive in the
sensorless operation. At each switching on of the drive the initial rotor position is determined on the basis of the HF-injection. Additionally there is the option to synchronize to
the moving motor.
3.8.10.2 Commissioning at the sensorless operation of the synchronous machine
1
Selection of the motor from the motor database of ProDrive or the setting of the data
with the help of the motor type plate. The following values are necessary: nominal current, nominal speed, pole pair number, EMF-constant. The DC-link nominal value
must conform with the actual DC-link value.

the smoothing time may be selected.

3.8.10.3 Vibration damping
Vibrations can occur in the controlled operation during low speed. These vibrations can
be damped with an additional speed set value. Here the high-frequency component of the
Iq-I term is filtered and added to the speed set value.

The I-term is guided through a slow filter (Z133.59–) and a fast filter (Z133.58–) and the
difference is then multiplied by a damping factor (Z133.55–). This value is added to the
speed set value.
3.8.10.4 Motor diagnosis
In general the motor diagnosis checks if the notch position search with injection, the set
frequency (Z133.2–), the amplitude (Z133.3–) and the band width (Z133.4–) works and
therefore as well if a motor can be operated encoderless with injection. For this, the highly
frequent voltage is injected in the motor and thereby the electrical angle is slowly increased by discrete steps. Then, the resulting demodulated signal is assigned to the angle in ProDrive (see figure) and can be evaluated. The motor diagnosis is started via the
bit 4 of Z123.1–.

3.8.11 Sensorless control for asynchronous motors (open loop)
3.8.11.1 Sensorless control
The drive controller b maXX® 3300 permits an operation of an asynchronous motor in
speed control without a rotary encoder (open loop control). However, a position controlled
operation (operating modes position control, synchronous operation, positioning, etc.) or
pure torque control is not possible.
The open loop control operation is based upon calculating the speed of an asynchronous
motor from its model. For this purpose, the motor data (as e. g. inductance and resistance) must be exactly known.
The motor voltages are not measured, but the voltage set values, which were calculated
from the motor control, are used instead. The dead time compensation must also be activated, so that the nonlinearity of the power unit can be compensated.
The reliability of open loop operation at low frequencies below 2 Hz is compromised by
the accuracy of motor model parameters and compensation of power unit nonlinearity.
Therefore, for applications requiring persistent operation in this region, it is recommended
to use the closed loop control with an encoder.
m Motoring operation at very low speeds (output frequency below 2 Hz) should be avoided.
m Generating operation at very low speeds (output frequency below motor rated slip)
should be avoided.
m Change of speed direction without load is possible.
m Generating operation until standstill is possible.
m A longer lasting generator-based operation (1-2 sec) at very low speeds is not possible.
m The persistent operation at zero frequency is not possible.
m Operation with motors connected parallel is not possible.
Performance specifications
Frequency operation limits:
m Minimum output operation frequency motoring mode fmin_m = 2.0 Hz
m Minimum output operation frequency regenerating mode fmin_r = motor rated slip
m Maximum output operation frequency fmax = 150 Hz
Performance of closed-loop speed control:
m Control range = 1:100
m Static accuracy = 30% of motor rated slip
m Maximum speed regulation bandwidth = 15 Hz

Operating Modes
Hints to achieve best possible performance
1 PWM switching frequencies recommended: 2 kHz and 4 kHz
2 The auto-tuning of the current regulator and the identification of the magnetizing curve
(Lh characteristic) must be executed to measure optimal parameters for motor model
and for compensation of the power unit nonlinearity.
3 Parameter Dead time compensation Z47.50– may be decreased in small steps of 1%
in the range 100% - 90% to reduce the speed ripple and to improve starting performance.
4 Parameter Flux estimator gain Z163.1– may be increased in range 250 - 750 to
achieve smooth operation at low speed and to improve starting performance.
5 Parameter Minimum speed threshold OL Z161.1– can be decreased, if the operation
with frequency bellow 1 Hz is required or if smooth starting is needed. But the reliability
and repeatability of starting may be affected.
6 Parameter Minimum speed delay OL Z161.2– may be decreased to lock the flux estimation and prevent the loss of motor control at stand still. 
If the drive does not follow a deceleration ramp, e.g. drive in current limit, the parameter
may be increased to allow speed control down to zero.
7 Auto-tuning of the speed regulator (closed loop analysis) is not possible at open loop
control. The Ks Scaling factor Z18.40– must be calculated accordingly to the following
equitation:
K t 360 o
K s = -----  ----------J 2
8 Adjust the parameter Slip frequency warm Z107.16– which corresponds to rated motor
slip at rated load to decrease speed estimation error.
9 At enabling of the regulator the field current follows a ramp to build the flux. With parameter Magnetization time Z160.1– the length of the ramp can be set.

Operating Modes
3.8.12 Operating Mode U-f Characteristic
The b maXX 3000 drive controller allows the operation of motors according to U-f specification. Thereby simple applications can be realized at which the motor must be run at a
set speed. No encoder is needed and several motors can be operated at the same converter. For motor protection the U-f operation mode includes an overcurrent protection.
The operation is intended for simple applications with asynchronous motors.

U-f characteristic
The settings take place in functional block 166. With parameter maximum voltage
(Z166.13–) and Frequency Umax (Z166.12–) the slope of the straight line can be parameterized. Additionally the voltage is kept constant from the maximum frequency on. Via
the zero voltage (Z166.5–) a voltage can be set at frequency 0 Hz.
Three different operation modes are possible in general; U/f characteristic with and without overcurrent protection and a operation with the compensating controller for the acceleration (see chapter Z3.8.12.1–).At operation without overcurrent protection the
controller is switched off if the maximum current of the converter has been reached, only;
at operation with overcurrent protection the acceleration ramp of the maximum current is
stopped.
Additionally, at all operation modes a slip compensation is possible or an additional speed
controller if an encoder is connected. In ZFig. 163– the U/f operation with slip compensation is presented. The speed controller is activated via bit 4 of Z166.1– so that not the
additional frequency from the slip is added but the output. It reduces the acceleration insofar.

Control loop of U-f operation
NOTE!
At operation without overcurrent protection a too high current can be impressed in the
motor.
The controller switches off automatically if the maximum current for the controller is
reached.
3.8.12.1 Compensating controller for acceleration
In order to reach a dynamic operation via the U-f control, the compensating controller is
the option for the acceleration (bit 0...1 = 2 of Z166.1–). Thereby, different current limits
dependent of the maximum current can be defined for the motoric as well as the regenerative operation. If the current exceeds the set limit then the compensating controller is
activated for acceleration. It reduces the acceleration insofar that the maximum current is
always applied and the motor is operated with the highest possible acceleration.
Hereby in the regenerative operation additionally an operation with a voltage controller is
possible so that the converter can be operated without braking resistors. If the DC link
exceeds the set threshold the maximum current is reduced and consequently the torque
as well that brakes the motor.
A block diagram for the control is presented in ZFig. 164–.

Operating Modes
Figure 164:
Compensating controller for acceleration
If the speed ramp was set too steep at a high load torque, it can happen that the drive
cannot be accelerated furthermore. In this case the frequency can be reduced at a constant frequency (bit 7 of Z166.1–) to enable the drive acceleration.
3.8.12.2 Current control
If a specified torque is required to operate at low frequencies the current control at low
frequencies (bit 3 of Z166.1–) is recommended. An additional voltage (Z166.20–) is applied at the set frequency threshold (Z166.17–) via a PI controller, so that at least the set
current (Z133.22–) or maximum current (settable via bit 8 of parameter Z166.1–) is applied to the motor.

3.8.13 Operation mode Coupled mode
The coupled mode is activated via the parameter Set operation mode Z109.1– = -12. In
this operation mode and based on the cyclical transferred master axis position the position set value of the drive is generated by using polynomial curves.
The operation mode allows the following setting options:
m The braking from the current speed to speed = 0 after the operating mode switchover
m The synchronization of the current position with the position set value from the
curve.
m The changing the sequence of the single polynomial segments.
m The reloading of curves or sub curves during operation
m The gear factor at the curve output
m The superpositioning of the curve movement by an additional movement
m The execution of curves towards the forward as well as the backward direction
The entire set curve is combined with several curve segments. Thereby each curve segment is defined by a polynomial of the ninth order. ZFig. 166– describes the schematic
diagram. This curve consists of seven curve segments, which are linked up as a linked
list. Therefore, it must be specified which curve segment is to be the following and the
previous one when defining a segment.

Description
Curve segment number
The unique number of this segment in the curve. 65536
segments can be created at the maximum whereby each
segment may exist once, only.
Type of curve
Currently there is one curve type permitted – the polynomial of 9th order. If polynomials of lower order are used the
coefficients that are not required must be set to 0.
Coefficients
These are the coefficients which define the polynomial
function.
Traversing – master axis
The distance of the master axis for which the curve segment is defined, e.g. 135°.
Traversing - drive
The distance of the drive for which the curve segment is
defined, e.g. 1 revolution and 32°.
Predecessor segment
Here is the segment number of the curve segment which
precedes from this curve segment.
Following segment
Here is the segment number of the curve segment which
follows this curve segment.
At this point it is important that a single segment isn't bound to a fixed position of the master axis or of the drive due to its definition. A certain distance of the master axis and the
drive is defined by a segment. The starting point of a segment is the terminal point of the
prior segment and the terminal point of this segment is the starting point of the following
segment.
To establish a reference to the absolute position of the drive a starting segment must be
defined. This is segment 2 in ZFig. 166–. Additionally the position of the master axis and
of the drive must be specified at the starting point of segment 2. This is done by the parameters Z122.7– to Z122.11–.
The entire curve is created by ProCam and is transferred as a file to the controller.
The structure of the operation mode Coupled mode is described in ZFig. 167–. Basically
the position of the master axis is transferred cyclical to the drive. The positioning set value
is calculated by the drive from the master axis position and the existing segments of the
polynomial curves. Thereby the available options of this operation mode are considered.
A gear factor is evaluated if required and overlaid by an additional movement before the
position set value is transferred to the position controller.

3.8.13.1 Transmission of master axis position
The current position of the master axis is specified by the parameters Z122.3– and
Z122.4–. Thereby the parameter Z122.3– indicates the revolutions of the master axis
and the parameter Z122.4– the angle. Both parameters can be written cyclical by a PLC.
The revolution information oft he master axis is ignored by setting bit 4 in the parameter
Z122.2–. Now, only the angular specification of the master axis is important. If the synchronization to the polynomial curve was selected after starting (Z122.2– bit 0), always
the position in the curve is synchronized, which is within the first master axis revolution.
3.8.13.2 Transmission of the curve data
The polynomial curve segments are transmitted as a file in the *.bmcam format. Such a
file can be created with ProCam.
The curve data file is always filed in the RAM of the controller at transmission. After restarting the device the curve data is not available anymore and therefore must be loaded
again.
There are two different modes for the downloading of curve data. Overwriting the present
file or reloading a second file.
Overwriting the curve data
When overwriting the curve data the present curve file is replaced by the new file, which
was loaded. The overwriting of the file is possible only if there is no polynomial curve
which is processed at the present time. The controller denies overwriting of the present
curve file during an active processing. Overwriting at file transmission is selected by the
file option = 0.

Operating Modes
Reloading curve data
When reloading the curve data the file which already is on the drive is combined with the
downloaded file and then is activated. To reload curves at the data transmission the file
option is set to 1. There are two options to activate these reloaded files. The user either
activates the combined file via the control word or via the angular overflow of the master
axis. The selection is made by setting or resetting bit 5 in Z122.2–. Generally the drive
sets bit 8 in Z122.1– and Z108.3– as soon as there is a combined curve. As soon as a
switchover is made to the combined curve the drive resets this bit again.
An intentional activation of reloaded files via the control word or the angular master axis
is required at an actively process curve, only. If the coupled mode isn't processed actively
then the existing file is immediately combined with the reloaded file and if the operation
mode is started the next time the combined curve file already will be processed.
If a curve is reloaded but not activated in the active operation the drive combines both of
the curves when inhibiting the drive so that the combined curve is available at the next
enable.
The sequence of the curves is the following:
– One curve is assumed, which exists of two segments with the segment numbers 1
and 2. The user reloads a curve having the segments 1 and 3.
– Segment 1 exists in both curves. The segment from the reloaded curve is taken into
the combined curve.
– Segment 2 exists in the original curve only - therefore it remains in the combined
curve.
– Segment 3 was defined in the reloaded curve only - therefore the combined curve is
extended with segment 3.
The following diagram shows this process:
Original curve

Deleting curve data
If bit 6 is set in Z122.2– the curve data is deleted. Since parameter Z122.2– can only be
written if the drive is disabled, the polynomial curve can only be deleted in this state.
3.8.13.3 Changing the chaining sequence
The sequence of the single segments can be changed during operation. Two parameters
(Z122.6– and Z122.41–) are available for this. Based on an example this procedure is
to be explained.
It is assumed that there are five curve segments on the drive controller. Segment 1 is to
be defined as the starting segment. The specified chaining is only processing three segments currently - these segments are shown in the following table.

The segments 4 and 5 are not active at the current chaining. These shall be connected

The parameters Z122.6– and Z122.41– are written to as follows:
P122.6 = 0x00010004 and P122.41 = 0x00050003 (see description of Z122.6– and
Z122.41–)

The active curve now consists of four segments. Segment 2 was removed from processing and the segments 4 and 5 are now actively processed.
NOTE!
It is necessary that the parameters Z122.6– and Z122.41– always are valid as the
controller always performs both operations (decoupling and coupling) - both parameters must have the same value.
If for example only one decoupling has to be performed, than the value of both parameters must be identical. Then this operation is executed twice but as they are
identical this is not relevant for the application.
Sequence of chaining change
In the following the sequence of chaining change is described. Thereby, the handshake
between the control and the controller has priority.
m The parameters Z122.6– and Z122.41– describe the chaining information.
m The control sets bit 5 in the control word Z108.1– to activate the chaining change.
m The drive sets bit 12 in the status word Z108.3– to signal that chaining was
changed.
m The PLC resets bit 5 in the control word Z108.1–.
m The drive cancels bit 12 in the status word Z108.3–.

The correct positioning within the chained polynomial curves can be found by specifying
the starting point, as described in chapter Z3.8.13–.
3.8.13.5 Synchronization
Synchronization to consisting motion
If switching online into the coupled mode while the drive is in motion then the current
speed and acceleration is applied and the drive is decelerated to speed = 0 by an S-curve
profile. For this the parameters to synchronize motion Z122.12– to Z122.15– are used.
This procedure can be switched on and off using bit 9 of parameter mode Z122.2–.
NOTE!
If synchronization is switched off velocity and acceleration jumps can occur!
Synchronization to the polynomial curve
Via the parameter mode (Z122.2–) a synchronization of the curve can be selected with
the current position of the master axis. The controller detects the current position set value from the polynomial curve by the start curve segment, master axis positioning and
drive positioning. If the momentary angle actual value of the drive doesn't correspond to
the set value from the polynomial curve then the controller is able to independently position to the required angular position from the polynomial curve. This positioning operation
limits the maximum speed (Z122.12–), the maximum acceleration (Z122.13– and
Z122.14–) and the maximum jerk (Z122.15–).
The servo controller can be positioned either to the required angle or to the absolute position including the revolutions which result from the polynomial curve. When positioning
to the total positioning the servo controller catches up on all revolutions that are required
to reach the absolute set position in the curve. The direction of rotation of both positioning
modes can be specified.
If the rotational information for the master axis is ignored then the servo controller finds
its valid master position always within one revolution from the starting point of the starting
polynomial. The synchronization movement doesn't require parts of the polynomial curve,

it's a positioning operation using the settable profile data via the parameters Z122.12– to
Z122.15–.
Activate / deactivate synchronization
If synchronization was selected (Z122.2– bit 0 = 1) the drive checks after the enable of
operation mode Coupled mode if the current position of the drive agrees with the set position from the curve. If this is not the case the drive generates a compensating movement
with jerk limitation from the current position up to the set position from the curve. The
curve movement thereby is overlaid by the synchronization movement.
If synchronization is off (Z122.2– bit 0 = 0) the synchronization movement isn't performed. In this case movement is started from the current position of the drive.
Synchronization modes
m Master axis stops during synchronization
By the setting of bit 1 in Z122.2– standstill monitoring is activated. This monitoring
checks if the master axis changes its position during synchronization to the polynomial curve. This is the case if the master axis speed is above the speed threshold
which is determined in Z122.16– "Standstill limit master axis". During an active
monitoring the error 2744 “Master axis moves during synchronization“ is activated.
The user can freely select the error reaction. 
m Positioning to the angle
The synchronization movement is executed on the angle if bit 2 in Z122.2– is selected, only. Thereby, the position of the drive is evaluated in the polynomial curve
and for synchronization movement the revolution part of this information is ignored.
Thus, the drive positions to the angle only and doesn’t catch up on the revolutions. 
m Specify rotational direction
If bit 3 in Z122.2– is set then a synchronization is executed towards the rotational
direction which was set in Z122.2– bit 7 (1: negative rotational direction; 0: positive
rotational direction). When synchronizing to the angle this isn’t decisive as one revolution at most is executed as a synchronization movement. This option turns into
an issue if it is to be synchronized to the absolute position of the drive. The synchronization can take very long if the rotational direction was selected unfavorably because the position is specified in 32 bit revolutions and 32 bit angle.
3.8.13.6 Use of the output-sided gear
At the output of the polynomial curve generator a scaling of the mean output values is
possible by means of a gear factor. This factor is specified by two parameters.
P122.42
Gear factor = ------------------P122.43
The gear factor is either taken over when starting the operation mode or it can be changed
during the active operation.
Parameter manual b maXX BM3000
595
Document no.: 5.12001.06
of 724
3.8
Operating Modes
When starting the parameter values of Z122.42– and Z122.43– are accepted as gear
factors. During the active operation the acceptance must be specifically initiated. This is
made via bit 8 in the control word Z108.1–. The sequence is the following:
1 The user sets the gear factor via Z122.42– and Z122.43–.
2 The user sets bit 8 in Z108.1– with a rising edge.
3 The drive changes the gear factor and accepts this by setting bit 13 in Z108.3– Status
word.
4 As soon as the user resets bit 8 in Z108.1–, the drive resets bit 13 in Z108.3–.
It must be considered that the gear factor causes an extension or reduction of the curve,
only. The synchronization always is performed on the original curve. If the extended or
reduced curve shall be the same reference point as the original curve, then it is important
that the master axis is in the starting point (this is defined in Z122.8– and Z122.9–) at
switchover of the gear factor.
3.8.13.7 Overlaying using an additional movement
The curve can be shifted in the Y-direction by overlaying the polynomial curve with an additional movement.
The distance of this overlaid movement can be specified in the parameter Target position
offset (Z122.17–). This parameter is signed including the following information:
1 sign bit
15 bit revolutions
16 bit angle
Therewith, the overlaid movement of 32767 revolutions at maximum and 359.99° in the
positive and negative direction can be defined.
This movement can be initiated only, if the Coupled mode is active and the drive signals
that it is processing the curve by setting bit 10 in Z122.2–. The activation works the following way:
1 The additional movement is defined by the parameters Z122.17– to Z122.21–.
2 The additional movement is activated via bit 6 in Z108.1– "Control word".
3 As soon as the additional movement is running the drive sets bit 2 and resets bit 10 in
Z122.1– Status.
4 After the additional movement was completed the drive resets bit 2 and sets bit 10 in
Z122.1– Status again.
During an ongoing additional movement changes of the profile data (Z122.18– to
Z122.21–) and the target position compensation are not taken into account. The rising
edges in the control word bit 6 are ignored till the additional motion is reported as completed by the status.
During the processing of the additional movement it is checked if the additional movement
and the polynomial curves exceed the limited positioning difference in the drive per field
bus cycle. If this is the case the drive will stop operation due to the error 910. The user
must be aware that the speed and acceleration of polynomial curves add up. This has to
be possible in the application.

3.8.13.8 Intermediate buffering of curve segments
To process the curve segments efficiently in the firmware of the drive, from a great
amount of curve segments that belong to an entire curve, three segments are loaded into
an intermediate buffer which can be accessed fast by the firmware.
Due to the buffer handling delay times can occur when changing the segment sequence
and activating reloaded curves.

Figure 168:
Switchover of segments
Effects at sequence change
In ZFig. 168– two cases are described. The original curve is shown in black and exists
of the segments 0-6. The user tries to replace the segments 1-5 by means of a sequence
change of the segments 7-11 (red partial curve). In ZFig. 168– two different switching
times are shown for this switching procedure. The content of the intermediate buffer is
indicated by the colored bars below the coordinate system.
Specifically this means that if segment 0 is active when switching over then the intermediate buffer includes the segments 6, 0 and 1. This is understandable, because the active,
the prior and the following segments always are provided. However, the segments in the
intermediate buffer still must be processed. That means that segment 1 follows segment
0 as this is situated in the intermediate buffer already. After segment 1 segment 2 is processed and so on. After switching over into segment 0 the black curve is processed once
more. Not until the next run after segment 0 the junction to segment 7 takes place and the
red curve is processed.
In the second case shown the switchover is triggered in segment 6. In this case the segments 5, 6 and 0 are in the intermediate buffer in this case. Here, the segment 0 is activated after the segment 6, because it is in the intermediate buffer already. After segment
0 the segment 7 is loaded already and follows segment 0. In this case the switchover immediately takes place.
So that switchover to other curve ranges (e.g. branching) is activated during this run, the
switchover must be made two segments prior to the branching point.

Operating Modes
Effects when reloading curves
Supposed the original curve corresponds to the black curve in ZFig. 168–. The user reloads a curve during the process, which is in accordance with the course of the red curve.
After reloading and combining segment 7 of the red curve complies with the segment 1
of the newly combined curve. The newly combined curve consists of 7 segments whereas
the segments 1-5 were changed due to the reload.
When activating the curve the activation time is decisive. If the curve in segment 0 is activated then the segment 1 of the original cure is already loaded in the intermediate buffer.
This segment must be processed before segment 2 of the combined curve can be loaded
and activated in the intermediate buffer. As the segments smoothly connect to one another segment 2 of the combined curve is connected to the segment 1 of the original curve.
An offset occurs and the required curve position isn't reached.
If the switching to the combined curve occurs in segment 6, the segments 5, 6 and 0 are
loaded in the intermediate buffer. Segment 0 follows segment 6. After segment 0 the segment 1 of the combined curve is loaded in the intermediate buffer and is processed. In
this case the required processing of the curve is achieved.
While reloading the curves the curve segment in which the combined curve is switched
and the following segment in both curves shall be identical in the original as well as in the
combined curve.

3.9.1.2 Description of the Parameters
6.1
Standstill threshold

Positive overspeed limit
When the drive exceeds this positive maximum speed limit, the drive is immediately deenergized by error message 203 "Positive overspeed limit exceeded".
The clock of the overspeed monitoring is 1 ms.
6.6
Negative overspeed limit
When the drive exceeds this negative maximum speed limit, the drive is immediately deenergized by error message 204 "Negative overspeed limit exceeded".
6.7
Max. pos. speed deviation
Speed control deviation limit.
The maximum permitted positive difference between set value and actual speed (positive
speed error limit) is set here for each axis.
Exceeding this limit through the response time set in Parameter Z6.11– will lead to error
message 201 "Exceeded limit pos. speed control deviation".
The clock of the monitoring of the speed control deviation is 1 ms.
The parameters Z6.7– Max. pos. speed difference, Z6.8– Max. neg. speed difference
and Z6.14– Velocity window percentage are used to generate the "Nact = Nset" message.
For details see the description of Z18.20– Speed controller status.
6.8
Max. neg. speed deviation
The maximum permitted negative difference between set value and actual speed (negative speed error limit) is set here for each axis. Exceeding this limit through the response
time set in Parameter Z6.11– will lead to error message 202 "Exceeded limit neg. speed
control deviation".
The parameters Z6.8– Max. neg. speed difference, Z6.7– Max. pos. speed difference
and Z6.14– Velocity window percentage are used to generate the "Nact = Nset" message.

Speed error response time
The maximum time is specified here in ms for each axis in which the set limit values of
the speed difference (Parameter Z6.5–, Z6.6–) may be exceeded before a drive error
will be triggered.
6.12
Speed actual value > Speed ON threshold
The ON threshold of the free adaptable speed threshold with hysteresis is set here. If the
absolute value of the Z18.22– Speed actual value exceeds this threshold (Z6.12–), bit 8
in Z18.20– Speed controller status is set. The bit will be canceled again if the value falls
below the OFF threshold (Z6.13–).
6.13
Speed actual value > Speed OFF threshold
The OFF threshold of the free adaptable speed threshold with hysteresis is set here. If
the absolute value of the Z18.22– Speed actual value is fallen below this threshold
(Z6.12–), bit 8 in Z18.20– Speed controller status is canceled. The bit will be set again
if the value exceeds the ON threshold (Z6.13–).
6.14
Velocity window percentage
The percentage parameter relates to the current speed set value (Z18.21–). It is used for
generation of the "Nact = Nset" message in Speed controller status (Z18.20– bit 12).
Condition for "Nact = Nset" :
Z18.23– e2 Speed error Z18.21– w2 speed set value * 
Z6.14– Velocity window percentage
In addition to Z6.14– both absolute limits (Z6.7– and Z6.8–) are used for generation of
"Nact = Nset"! For details see the description of Z18.20– Speed controller status.
At 0% the parameter Z6.14– Velocity window percentage is not used for generation of
"Nact = Nset" message.
6.20
Blockade speed limit
Standstill threshold for blockage monitoring.
The blockage monitoring detects a block when the speed control is at the current limit and
the drive at the same time at standstill (|Nist| < Blockade Speed Limit).
The threshold for the actual speed under which the drive is assumed to be blocked can
be set under this parameter.

This speed threshold must be adapted depending on the motor or encoder system (especially at resolver). The threshold must be higher than the variation of the speed actual
value in standstill.
An adjustable hysteresis (Z138.28–) is used for the condition speed controller at current
limit. In particular at motors with resolver and at little speed set value it can be necessary
to adapt this hysteresis because the speed controller is possibly not permanently at the
current limit.
The clock of the blockage monitoring is 2 ms.
6.21
Blockade time limit 1
Warning threshold for the time of blockage monitoring.
If the conditions for blocking have been met, a warning (Code No. 209) will be triggered
upon expiration of the set blockade time limit 1. If the conditions for blocking are no longer
met, the warning 209 will be canceled by the controller.
6.22
Blockade time limit 2
Error threshold for the time of blockage monitoring.
If the conditions for blocking have been met, the error (Code No. 210) will be triggered
upon expiration of the set blockade time limit 2.
Blockage monitoring will be deactivated when this parameter is set to 0.
6.25
Power unit peak current
This parameter serves as a display of the peak current (Z129.16– to Z129.19–), if the Ixt
model for the PU overload monitoring is used or Z129.85– to Z129.88–, if the temperature model is used instead. See PU temperature model state (Z175.2– Bit 0) depending
on the PWM frequency Z130.15–.
6.26
Power unit nominal current
This parameter is used to display the nominal current of the power unit (Z129.12–,
Z129.13–, Z129.14– or Z129.15–) depending on the PWM frequency Z130.15–.
6.27
Power unit Ixt actual value
This parameter displays the current Ixt value of PU overload monitoring. The current will
be limited to the power unit nominal current with a value of 100%.

At nominal load devices (peak current = nominal current) the current is limited to nominal
current. Additional monitoring and limitation is not required.
The Ixt-actual value is not calculated at nominal load devices and there is no current reduction.
This parameter is important if the PU overload monitoring is not executed via the temperature model (see "Status PU temperature model' Z175.2–, only.

(the dead time voltages are compensated, independent of the 
value of the dead time compensation factor Z47.50–, i.e. it 
doesn't matter if the dead time compensation in the motor is 
active or not)
The parameter >6.32< accords to the smoothed value of pe real. 
Filter time constant 1,25 ms.
The uncertainty in the power indication is determined by current and voltage measuring
uncertainties (at the voltage it is the efficiency uncertainty).
Therefore it is recommended to carry out the dead time measuring (see chapter
ZAutotuning of Current controller– from page 155). Typically the uncertainty of the power
indication is at +/- 2% of the nominal power of the device.
NOTE!
The BM33XX isn't a measuring device and may not replace a power measuring device. The value shown in the parameter >6.32< is just a benchmark
NOTE!
If the power indication >6.32< is evaluated and PWM frequency changes are made
during operation, the adaption of the dead time compensation must be activated after
the PWM frequency (see Z123.1– bit 3) independent of the dead time compensation
being active in the motor control or not (see Z47.50–).

NOTE!
Before the PWM reduction can be released the user must assure the following:
m The drive must operate correctly with the reduced switching frequency (e.g. measuring data of the motor, control quality at reduced current controller band width
a.s.o. must be checked).
m The drive components must tolerate the reduced switching frequency (e.g. check
motor filter, if it is existing). This is very important, if the PWM frequency is reduced
to 2 kHz.

The 2nd dimension corresponds with the discrete distance intervals. The array is indicated with 200 elements; however, this limit is dynamic depending on the number of active
recorded channels.
The data type of the array is FLOAT32. Depending on the data type of the recorded channel, the raw data is stored in the memory in the format of the source data type (always
stored in 4 bytes).
The corresponding axis can be addressed through the SubDevice Index. The internal
controller ring buffer is organized 3-dimensional accordingly.
If no data is present in the ring buffer, the Read command response with error code:
RC_ERR_RSP_NODATA (1305)
If an attempt is made to read data from the buffer during recording, the Read command
responds with error code: RC_ERR_RSP_NOREAD (1304)

FFT length
This parameter can be used to enter the length of the time window for FFT evaluation.
Entries are only possible with the FFT command Stop. The length applies to the two channels and may only be as Radix 2 (power of 2).
The length is decisive for the frequency resolution.
Example:
Sampling frequency 4 kHz (0.35 ms cycle), which means the maximum frequency is
2000 Hz. With an FFT length of 4096, the FFT has results in 2048 discrete value pairs
(real, imaginary) plus DC share. The frequency resolution is 2000 Hz /2048 = 0.9765 Hz.

Since the FFT always works with a time frame (finite time record), the use of a window
function usually makes sense. The Window function serves to reduce the "Bin Leakage"
or "Side Lobe". The price for that is a certain reduction of frequency resolution. The
change of the Window type does not take effect until the FFT Command is (re) started.

3.10.1 Automatic controller and filter setting
An automatic system identification can be processed with the controller. After its determination an automatic controller and filter setting can be processed. In ProDrive the system
identification is processed in the window Optimization  Control Loop Analysis (see
ZFig. 171–). For this purpose the motor must be operated at a speed controller in speed
control, which was set low. The other possibility is to operate in current control with a low
current presetting. Noise is added to the additional current setpoint by "Start analysis".
The evaluation of the measuring values is processed via the FFT module. This evaluation
determines the response of the amplitude and the phase response. After that is checked,
if the controlled system is a two-mass vibrational system. At a controlled system without
resilience, the motor moment of inertia Jm, Ks, Kp and Tn of the speed controller is calculated, additionally. With a two-mass vibrational system, the load moment of inertia JL,
the rigidity c, the attenuation d and filter settings are proposed additionally. The controller
can be set set higher or weaker via the requirements for the phase margin and for the
amplitude margin.

The gain Kv of the position controller is proposed additionally, because of the bandwidth
of the speed controller.

3.10.2 Torque ripple compensation
Synchronous motors normally have ripple torques. This can cause speed variations in the
speed control, because the torques cannot be adjusted quickly enough. The controller
can compensate these ripple torques. A feedforward of an additional current torque is
generated, in which an additional current torque is generated in dependence of an electric
or mechanic angle.
Figure 172:
Torque ripple compensation
Before operation of the controller, an identification of the torque ripples can be made. The
required currents are measured here and then are preprocessed. Then the additional current set values are saved in the table.

3.11 Monitoring
3.11.1 Field angle monitoring
Field Angle Monitoring on Synchronous Machines
The controller determines the pole wheel direction of the rotor with the aid of the motor
model. This is then compared with the pole wheel direction which is calculated from the
encoder used for motor control. When the monitoring is enabled (i.e. the monitoring
threshold Z143.8– is not equal to 0), if there is an angle error greater than 45° (electrical),
Bit 8 of Parameter Z143.1– is set and the error message
211 Error While Monitoring the Field Angle
is initiated. The pulse enable is blocked as a result.
The cycle time of the monitoring part for error triggering is 1 ms.
Additionally, the field angle monitoring can be switched on and off by setting the field angle speed threshold (143.8) as a function of the speed set value. If the speed is less than
the field angle speed threshold (143.8), the monitoring remains disabled.
Field angle monitoring only functions for the encoder which is set for motor control.

is available for each sampling time of the position controller.
The static position error limit becomes effective when the position controller either does
not receive a new position set value or it continues to receive the same position set value
repeatedly.
Two separate limits (thresholds) are available for position error monitoring. The following
property settings may be entered for each limit:
m Size of the window (position error limit)
m Response time (position error time)
m Type of monitoring - static, dynamic or both (see Mode 1 Z143.2– and Mode 2
Z143.5–)
Two bits are assigned to each threshold in the Parameter Z143.1– Status. If the actual
position error exceeds one of the two thresholds, the bit "Position Error Limit Exceeded"
will be set in the Z143.1– Status. If the position error remains longer than the position
error time that was entered, another bit is set in the Status and the error
207 Position error limit 1 exceeded or 
208 Position error limit 2 exceeded
will be reported.
If the position error falls below the threshold setting, the status bit "Position error limit exceeded" will be deleted again.
The cycle of the position error monitoring is 1 ms.

Position error monitoring combines the two settings above and is thereby always active.
143.3
Position error limit 1
Limit 1 for position error monitoring.
If the current position error (control deviation) is greater than the position error limit 1 setting, this will be immediately displayed in Z143.1– Status with Bit 0 = 1.
In addition, the position error limits 1 and 2 determine the status message "Set value

in the Z108.3– Status word 1, only in operating modes position control (Z109.2– = -4)
and synchronous operation (Z109.2– = -5)).
If the position error is within both position error limits (Z143.1– Status Bit both 0), then
the message "Set value reached" will be displayed immediately. If the position error is
even outside one of the position error limits and this position error limit is active at the
same time (static and/or dynamic) (Z143.1– Status Bit 0 or 4 are 1), "Set value reached"
will be deleted immediately.

3.11.3 Overload monitoring of the power unit
NOTE!
At nominal load devices (peak current = nominal current) the current is limited to nominal current. Additional monitoring and limitation is not required.
The thermal load factor (Ixt-actual value Z6.27– or the thermal load Z175.15–) is not
calculated at nominal load devices and there is neither current limit nor PWM reduction.
Overload monitoring protects the power unit against thermal monitoring. Thereby thermal
load is emulated and monitored by a model. There are two methods for this:
m Temperature model (enabled, if complete thermal data set is available in the device's characteristics (Z175.2– bit 3 = 1) and if the temperature model is selected
(Z175.1– bit 1 = 1, from V10.10 onwards)).
m Ixt model (is operated, if the temperature model is not enabled).
Parameter Status PU temperature model Z175.2– bit 0 displays, which method is enabled.

mains- and DC link voltage as well as the thermal data of the semiconductors. The PU
temperature model is divided into two sub-models. The I2t-sub-model, which protects
conductors/capacitors and the power electronics sub-model, which protects the power
electronics.

Current derating at changed operating conditions
For the following operating conditions correction factors are used during the current derating at changed operating conditions:
m Control cabinet temperature of device (ambient temperature or surface temperature): Required temperature can be entered in Z175.3–.
m Installation altitude: Required installation altitude can be entered in Z175.4–.
m Voltage supply (mains voltage/DC link voltage): Required mains voltage or DC link
voltage can be entered in Z175.5– or Z175.6–.
m Current derating dependent of the output frequency Z47.49–.
This is described in the chapter "Correction factors at changed operating conditions" and
"Electrical data" in the operating manual.

If the output value of the I2t-sub-model (PU-I2t-actual value) reaches 105% of Z175.8–
the warning 206 is set and the apparent current is limited to the maximum PU continuous
current Z175.7–.
If the PU-I2t actual value reaches 95%, the current limit is canceled on the part of the I2tsub-model.
If a current limit is additionally activated by the power electronics sub-model, the warning
206 remains. The warning and the limit is disabled not before the current limit is canceled
from both sub-models.
Power electronics sub-model:
The temperature of power electronics is emulated and is standardized using the temperature threshold Sem pu (temperature actual value = Sem pu corresponds to 105% load),
which was defined in the characteristics of the device. Thus, the load value is compatible
to the I2t-sub-model.
If the value reaches 105%, warning 206 is set and the apparent current is limited to the
maximum PU continuous current Z175.7–.
The power electronics sub-model cancels the current limit after Sem pu falls below the
value 105% within 30 s. The 30 s time slice is an empirical value, which is great enough
so that all devices can recover thermally.
However, the current limit still can be activated by I2t-sub-model.
NOTE!
m As long as the safety function current limit is active and the output frequency is
Z47.49– < 15 Hz (current derating dependent of output frequency is active), the
apparent current is limited to the lowest existing value of the maximum PU continuous current Z175.7–. This means, that during this time the current limit can be
lower, if the output frequency drops. However, the current limit cannot become
greater, if the output frequency increases.
m At the protective function current limit the "Max. drive current available" Z19.5– is
reduced, whereat the settable limit of the apparent current "Max. drive current"
Z19.6– isn't changed. The reduction of the apparent current takes place via the
current torque, i. e. via the "Max. available torque current" Z19.8–.
Protective function PWM reduction
In order to avoid current limiting, the switching frequency can be automatically reduced
(i.e. PWM frequency Z130.15– is halved). Thereby, the switching losses in the IGBTs are
reduced.
If the temperature of the power electronics exceeds the temperature threshold
Sem LimRed , the PWM frequency is halved and warning 216 is triggered. The temperature threshold Sem LimRed is lower than the threshold Sem pu , which triggers the current limit.
The PWM reduction doesn't change the value of the PWM frequency Z130.15–, which
was set.

Monitoring
The instantaneous (operating) PWM frequency is displayed in parameter Z130.41–. At
the same time the corresponding instantaneous (operating) cycle time of current controller is displayed in parameter Z47.65–.
In some circumstances the switching frequency reduction isn't enough, to avoid a current
limit.
If PWM reduction was activated, the device returns to the PWM frequency Z130.15–,
which was set.
m not until after 30 s the calculated temperature is below the threshold Sem LimRed
and,
m if there is no current limit existent.
The 30 s time slice is an empirical value, which is great enough so that all devices can
recover thermally.
In general, the PWM reduction is not active. It may be enabled in Bit 0 of the PU temperature model mode Z175.1–. It can be enabled in the inhibited drive status, only.
PWM-reduction is subject to the same limitations as at switchover to the set PWM-frequency during the continuous operation (see Z130.15–). They are available for the operating modes speed control and current control - they aren't available for SM sensorless.
The failures in the controller were minimized during the implementation of the PWM
changes in the continuous operation. However, they cannot be excluded. Therefore, this
option is applicable to simple (not critical) applications, where the drive tolerates possible
failures.
If the PWM frequency Z130.15– is set to 2 kHz or if the precondition "Current cycle <
RT0" wasn't considered during the reduction, PWM reduction cannot be processed.
NOTE!
m The user must assure that the drive with the reduced switching frequency can operate correctly (e. g. check rated motor data, control quality at the reduced current
controller-bandwidth etc.) before the PWM reduction is enabled. (Bit 0 of the PU
temperature model Z175.1– must be set). Furthermore, the drive components
must be checked, if they tolerate the reduced switching frequency (e.g. check motor filter if existing). This is particularly important, if PWM frequency was reduced
to 2 kHz.
m At the PWM reduction must be considered that the adjusting range of the output
frequency is reduced. The adjusting range is reduced from 450 Hz to 225 Hz if a
switchover from 4 kHz to 2 kHz is made (see chapter "Technical Data" in the instruction handbook of the device).

Monitoring function - explanations
Phase monitoring - not for axis units
This monitoring function checks the mains voltage of the three outer conductors. If one
outer conductor is missing, then the warning "Phase failure" is reported after a period of
> 4 s.
If all three outer conductors are missing, then the warning "Mains failure" is reported to
the controller after a period of > 4 s. After the preset time lag has been reached (based
on a mains failure monitoring parameter), the controller generates the error message
"Mains failure".
NOTE!
If no electrical filter is used during operation, mains and phase failures are detected
within 100 ms. If the device is operated with an electrical filter, the mains and phase
failures are detected after a max. of 5 s. Depending on the load condition, the failure
can also be detected much earlier, however.
Overcurrent
This monitoring function checks whether the motor current is larger than the 1.3 times the
peak output current. This aids "disaster prevention" in case of a short circuit on the output
side.
DC link
This monitoring function checks the voltage in the DC link. If the voltage drops below an
internally set value (approx. 50 V under the specified value), the controller reports "DC
link undervoltage" and a warning is signaled. If the voltage rises above an internally set
value (approx. 820 V), the controller reports the error "DC link overvoltage" and a pulse
inhibit takes place immediately.
Overload monitor- This monitoring function checks the present load as to whether the power unit can output
the peak current at this time. If the peak current is not possible, then the message "PU
ing
monitoring approached; max. torque current was limited" (warning 206) is reported.
Temperature of
device interior
This monitoring function checks the temperature in the interior of the device.
m If the temperature is higher than the warning threshold, then the controller signals a
warning.
m If the temperature is too high, then a pulse inhibit takes place immediately.
Heat sink temperature
This monitoring function checks the temperature of the heat sink.
m If the temperature is higher than the warning threshold, then the controller signals a
warning.
m If the temperature is too high, then a pulse inhibit takes place immediately.
Motor temperature This monitoring function checks the temperature of motor. If the I2t-threshold is exceeded,
then the error message "I2t overload" is reported by the controller.
Only for
KTY84 encoder
If the set temperature threshold 1 is exceeded, then the warning "Temperature threshold
1 exceeded" is signaled by the controller.
If the set temperature threshold 2 is exceeded, then the warning "Temperature threshold
2 exceeded" is signaled by the controller.
The KTY84 encoder has a minimum measured value of approx. -30 °C. If this temperature is gone under, or if a short circuit occurs at the encoder, then the error message
"Temperature probe short circuit" is reported.

The KTY84 encoder has a minimum measured value of approx. +250 °C. If this temperature is exceeded, or if the encoder is not connected, then the error message "Temperature
probe not connected" is reported by the controller.
For all 
encoders
If the threshold set (type-specific) in the temperature switch or in the MSKL encoder is
exceeded, then the error message "Overheating" is reported by the controller and a pulse
inhibit takes place immediately.
Position controller This monitoring function checks the position error limit statically/dynamically. If the current position error is statically/dynamically larger than the set position error limit, then the
error message "Static position error" or, respectively, "Dynamic position error" is reported.
After the monitoring period (position error period) has ended, an additional error message
is reported and a pulse inhibit takes place immediately.
Safety technology This monitoring function checks whether the safety function Safe Torque Off (STO) is activated. If the drive is enabled at the moment of triggering the safety function, an error
message is generated. If the drive is not enabled, a warning is displayed.
Blockage monitor- This monitoring function checks the motor speed and the motor current. 
ing
If the "Blockage monitoring interval" time frame meets the following two conditions, then
the error message/warning "Drive blocked" is signaled by the controller and a pulse inhibit
takes place immediately.
m Motor speed = 0
m The motor current output by the device is the same as the set motor limiting current
(current limit).

Error detection
Error detection
The illumination of the red LEDs H14 (axis 1) and H24 (axis 2) on the front of the housing
signals the occurrence of a error status.
A max. of 3 LEDs
are illuminated.
Essentially, the lowest red LEDs H14 and H24 "Error" are of significance here.
NOTE!
In case of warnings or errors without error reactions, the LEDs H14 or H24 blink "Error". Only error messages with error reaction will be signalized by constant lighting
up.
4.4
Error handling
Error messages, which can also be considered error lists, are the basis of the error handling.
NOTE!
The device is shipped with predefined error reactions. With regard to the error messages identified with "depending on the setting" in the "Reaction" column, the device's error reaction can be adjusted. Errors that, due to safety reasons, have an
immediate pulse inhibit as a consequence, may not be changed.
4.4.1
Error reset
If the red error LED is illuminated, at least one error is present.
Error reset cause all error messages to be reset. Individual resetting of errors is not possible. A reset causes deletion of the errors, if deletion was possible on account of the error
circumstances.
There are two methods of resetting an error:
m By means of write access to the control word
m Via a digital input
For further information on the subject of error reset, see "Instruction Manual b maXX

The start of the active operating mode requires a one-time reference
run (homing) after activating the controller.

Currently, only the operating mode Position Target Specification (BA
= 1) requires homing. This requirement can be activated in the mode
for the position target specification.

A homing error has occurred. Possible error causes:
No response
m An invalid homing mode was selected.
m Homing isn't possible because of limit switch and reference switch
status.
m A maximum distance was set for the zero pulse search and the
zero pulse was not detected within the specified distance.


Monitoring will become active as soon as the position set value is
equal to the target position at the end of positioning.

If the actual position is not located in the positioning window (Parameter 121.5) after the time set in Parameter 118.18 has expired, the
error will be triggered.

Error limit switch monitoring
This error occurs under the following conditions: 
No response

Case a: Both hardware limit switches set simultaneously.

Case b: Positiver software limit switch and negative hardware limit
switch active simultaneously.

Case c: Negative software limit switch and positive hardware limit
switch active simultaneously.


Possible causes: 
- Software limit switch set incorrectly, such as values for positive and
negative limit switches are reversed.
- Hardware limit switches are wired incorrectly.
- Errors on the cable for hardware limit switches.

Quick Stop

Set values were set in the operating mode Position Control with
cyclical set value position default (-4). These exceed the set speed
limit (parameter Z121.11–), the permitted mechanical maximum
speed of the motor (parameter Z121.11–) or the maximum interpolated set speed. 
If the error reaction „No Reaction“ occurs, the error is displayed and
the set speed is limited to the limit (Z121.11– or Z107.26–). Therefore, the input- and the output position drift apart.
The operating mode „Synchronism“ (-5) detected a speed (= master
axis speed) at the gear input. This causes an overflow at the set
