Movement monitoring (SPOS.MOV)
The bit SPOS.MOV indicates that the drive is moving. For this,
CMAX checks whether the speed signal exceeds the internal
limit (4 mm/s).
The internal status Drive in motion" is additionally filtered
with the switch−off time to simplify the evaluation in a PLC
program.
