Precondition
The motor holding brake is connected to the inverter.
Procedure
To commission the "motor holding brake" function, proceed as follows:
1. Set p1215 = 1.
The "Motor holding brake" function" is enabled.
2. Check the magnetizing time p0346.
The magnetizing time must be greater than zero. The inverter assigns the magnetizing
time when it is being commissioned.
3. Find out the mechanical opening and closing times from the technical data of the motor
holding brake.
– Depending on the brake size, brake opening times lie between 25 ms and 500 ms.
– Depending on the brake size, brake closing times lie between 15 ms and 300 ms.
4. Set the following parameters in the inverter 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 inverter will accelerate the motor
– If the motor waits too long before accelerating after the motor holding brake has
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:
– V/f control (p1300 = 0 to 3):
– Vector control (p1300 ≥ 20):

Set p1216 larger.
opened, 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.
Increase p1351 in small steps.
Increase p1475 in small steps.
