Comparison
Conventional
Hydraulic Drive
Servo-Direct-Drive
• Press Force Overload
10-20% of max. Press Force
• Uncontrolled movement of
the Cut-off Positions
• Power Input in Idle Running
approx. 40 - 60% of total
Power
• Continuous driving of the
Motor leads to high Power
loss and Oil heating
• Press Force Overload
< 1.5% of max. Press Force
• Controlled movement of
the Cut-off Positions
• Power Input in Idle
Running approx. 0.7%
of SspA
• Driving of the Motor only
by Press movement
therefore lower Power loss
and Oil heating
• Regualtion: by Valve
• Regualtion: by Servo-Drive
