A.2.7 Standstill monitoring
With the standstill monitoring it is clear that the target
position window is exited at a standstill.
When the target position is reached and the MC signal is
registered the drive enters the Standstill" status, the bit
Standstill_Control is reset. If, in this status, the drive is
removed from the standstill position window
for a minimum
defined time due to external forces or other influences, the bit
Standstill_Control will be set.
As soon as the drive is in the standstill position window again
for the standstill monitoring time, the bit Standstill_Control
will be reset.
