4. Set the following parameters in the converter suitably for the mechanical opening and
closing times of the motor holding brake:
– p1216 ≥ mechanical opening time of the motor holding brake
– p1217 > mechanical closing time of the motor holding brake
5. Switch on the motor.
6. Check the acceleration behavior of the drive immediately after the motor has been switched
on:
– If the motor holding brake opens too late, the converter will accelerate the motor
– If the motor waits too long before accelerating after the motor holding brake has opened,
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 holding
– If the motor waits too long before switching off after the motor holding brake has closed,
You have commissioned the motor holding brake function.

suddenly against the closed motor holding brake.
Set p1216 larger.
reduce p1216.
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.
Increase p1310 in small steps.
