Standstill monitoring
After the brake closing time and the waiting time for status monitoring have elapsed, the
standstill monitoring becomes active, i.e. the stop position is memorised and compared
with the permissible angle of rotation set in
(Lenze setting: 5°) when the brake is
applied.

When the stop position of the motor
axis has changed by more than the
permissible angle of rotation set in
despite the applied brake:
– The controller is enabled again and
the drive is held at standstill with
speed control to prevent a further
rotation/acceleration of the drive.
– The error output BRK_bError is set to
TRUE for one task cycle.
– The status "position drift when
brake is applied" is displayed at the
status output BRK_dnState via bit 21
for one task cycle.
