4.11 Configuring brake control
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 function diagram 2701 and 2704. The operating
principle of the holding brake can be configured via parameter p1215.
Figure 4-72
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 cancellation delay time).
Features
● Automatic activation by means of sequence control
● Standstill monitoring
● Forced brake release (p0855, p1215)
● Closing of brake for a 1 signal "unconditionally close holding brake" (p0858)
● Closing of brake after the "Enable speed controller" signal has been canceled (p0856)
Commissioning
Simple brake control is activated automatically (p1215 = 1) when the Motor Module has an
internal brake control and a connected brake has been found.
If no internal brake control is available, the control can be activated via parameter (p1215 =
3).
