Description
The "Simple brake control" is used exclusively for the control of holding brakes. The holding
brake is used to secure drives against unwanted motion when deactivated.
The control command for opening and closing the holding brake is transferred directly to the
drive via by the Control Unit that logically links and monitors the signals with the system-
internal processes.
The Motor Module then performs the action and activates the output for the holding brake.
The exact sequence control is illustrated in the SINAMICS S110 List Manual (FP 2701). The
operating principle of the holding brake can be configured via parameter p1215.
