5.6.8 Standstill monitoring
With the standstill monitoring it is clear that the target posiĆ
tion window is exited at a standstill.
When the target position has been reached and MC is sigĆ
nalled in the status word, the drive switches to the standĆ
still" state and bit SPOS.B6 STILL (standstill monitor) is reset.
If, in this status, the drive is removed from the standstill posiĆ
tion 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.
