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 trigger command for releasing and applying the holding brake is transmitted via DRIVE-
CLiQ from the Control Unit, which monitors and logically connects the signals to the system-
internal processes, directly to the Motor Module.
The Motor Module then performs the action and activates the output for the holding brake.
The exact sequence control is shown in the SINAMICS S120/S150 List Manual (function
diagram 2701 and 2704). The operating principle of the holding brake can be configured via
parameter p1215.
