6.9 Technological functions
4. Parameterize the opening and closing times of the motor holding brake
5. Restore the motor holding brake control
When a motor with a built-in holding brake is commissioned, a "clicking" sound in the motor
indicates that the brake has been properly released.

Opening the motor holding brake via P1218
Using parameter P1218, you can force the brake to open, e.g. in order to be able to
manually move a conveyor drive.

It is extremely important that electromechanical braking is controlled with the correct
timing (brake release time, brake closing time, release time) to protect the brakes against
long-term damage. The exact values can be found in the technical data of the connected
brake. Typical values:
– Brake release times are between 35 ms and 500 ms
– Brake closing times are between 15 ms and 300 ms
– The mechanical brake on the motor is connected to the Inverter through the motor
connector.
– To activate the motor holding brake, parameter P1215 must be set to 1.
