5.7.8 Standstill monitoring
With the standstill monitoring it is clear that the target
position window is exited at a standstill.
When the target position has been reached and MC is
signalled in the status word, the drive switches to the
standstill" state and bit SPOS.B6 STILL (standstill monitor) is
reset. If, in this status, the drive is removed from the standstill
position window for a defined time due to external forces or
other influences, the bit SPOS.B6 STILL will be set.
As soon as the drive is in the standstill position window again for
the standstill monitoring time, the bit SPOS.B6 STILL is reset.
