Maximum permitted stroke with active force control.
With active force control, the actual position relative to the start position must not change by more
than the amount specified in this parameter. In this way you can ensure that, if force control is actiĆ
vated by mistake (Workpiece missing" for example), the axis will not perform an uncontrolled moveĆ
ment.
This parameter is only taken into account during force control, if the CMAX has Operation enabled."
