6.7 Application-specific functions
Commissioning a motor holding brake
Danger to life due to falling loads
For applications such as lifting equipment, cranes or elevators, there is a danger to life if
the "Motor holding brake" function is incorrectly set.
• When commissioning the "Motor holding brake" function, secure any dangerous loads,
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 is pre-assigned during
commissioning and must be greater than zero.
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

DANGER
e.g. by applying the following measures:
– Lower the load down to the floor
– Cordon off the hazardous area so that nobody can enter it
suddenly against the closed motor holding brake.
Set p1216 larger.
opened, reduce p1216.
