Advanced commissioning
6.10 Motor holding brake
7. If the load sags after switching on the motor, then you must increase the motor torque
when opening the motor holding brake. Depending on the control mode, you must set
different parameters:
– U/f control (p1300 = 0 to 3):
– Vector control (p1300 ≥ 20):
8. Switch off the motor.
9. Check the behavior of the drive immediately after the motor has been switched off:
– If the motor holding brake closes too late, the load briefly sags before the motor
– If the motor waits too long before switching off after the motor holding brake has
You have commissioned the motor holding brake function.

For applications involving a pulling load, e.g. lifting gear/crane, if p1216 is too long,
then the load can briefly sag/sink after the motor holding brake is opened. If you
reduce p1216, then the amount that the load sags/sinks is reduced.
