9.3.18 Simple brake control
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 releasing and applying the holding brake is transmitted directly to
the drive via DRIVE-CLiQ from the Control Unit, which logically combines the signals with
the system-internal processes and monitors these signals.
The drive then performs the action and controls the output for the holding brake
appropriately.
The mode of operation of the holding brake can be configured using p1215.
Figure 9-7
The start of the closing time for the brake depends on the expiration of the shorter of the two
times p1227 (standstill detection monitoring time) and p1228 (pulse suppression delay time).
