5.6.8 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 signalled
in the status word, the drive switches to the standstill" state,
the bit SPOS.B6 STILL (standstill monitoring) 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 will
be reset.
