Description

The "Simple brake control" function is used exclusively for controlling 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 sequence control, is shown in detail in the List Manual (FD 2701). The
operating principle of the holding brake can be configured via parameter p1215.
