Notes on power operation
Control of the motor torque takes place indirectly by
means of the current regulation. All specifications on
forces/torques refer to the rated motor torque (relative
to the rated motor current). The actual force at the axis
should be calculated/checked and then set with external
measuring devices during commissioning.
Note
The following settings are required for parametrizing the
power operation (see Tab. 5/22)
– power window (permitted deviation from the nominal
value ascertained by the field bus)
– speed limitation (maximum speed which the drive
should reach). Without this specification the drive
would accelerate unbraked if there is no counter force
(e. g. work item missing).
– rest time (time during which the nominal force must be
applied, before “Motion complete” is triggered)
• Extend the rest time if the nominal force is already
achieved briefly due to the increased torque when start-
ing (before reaching the work item).
Power operation is prepared when the control mode is
switched over. The drive stands with the position controlled.
