Engaging and disengaging the motor brake

8.4.35 Engaging and disengaging the motor brake

COMPAX controls the idle holding brake of the motor and final stage. The time behaviour can be set using P17 and P211 Bit 2.

Application: If you are using an axis which is under torque when idle (e.g. when using a z axis), the drive can be engaged and disengaged in a manner which ensures that the load does not move. To do this, the drive remains powered during the reaction time of the idle holding brake. This can be set using P17 (see following diagrams).
