Safety
The servo drive supports motors with or without an integrated holding brake (electrical spring-oper-
ated brake). The holding brake is actuated automatically by the controller enable of the servo drive.
The actuation concept is based on the assumption that a drive that is already stationary is being held.
The actuation system is not designed for decelerating a moving drive. If a moving drive is decelerated,
this can cause excessive wear on the brake.
Motor configuration
Motor without holding brake
Motor with holding brake
Tab. 6: Example: removal of controller enable
The holding brake must be designed for the load torque to be stopped. Detailed information about
brake control è Online help for the CMMT-ST plug-in.
Supported encoders:
– BiSS-C encoders
– Incremental encoders
