Basic functions
7.15 Simple brake control
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 "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 using a parameter
(p1215 = 3).
NOTICE
Damage to the holding brake through incorrect parameterization
If parameter p1215 = 0 (no brake available) is set when a brake is present, the drive runs
with closed brake. This can destroy the brake.
Note
It is only permissible to activate brake control monitoring for booksize power units and
blocksize power units with Safe Brake Relay (p1278 = 0).
