■Returning enable direction to the movable range
• When setting ONLY_INSIDE in AxisName.Cd.SwStrokeLimit_Override, movement in the returning enable direction from
outside the software stroke limit range to the movable range is allowed.
• The returning enable direction from outside the software stroke limit range means the direction in which the axis can return
to the movable range without exceeding the ring counter value.
• If the axis operates to the direction to exceed the ring counter value from outside the software stroke limit range, the error
"Software Stroke Limit Over (start Position)" (error code: 1A01H) will be detected, and the axis will not start.
• Also, even if it is the returning enable direction, when an address which is outside the software stroke limit range exceeding
the movable range is specified as the target position, the error "Software Stroke Limit Over (Target Position)" (error code:
1A00H) will be detected, and the axis will not start.
• To return to the movable range ignoring the returning enable direction, set DISABLE in
AxisName.Cd.SwStrokeLimit_Override and carry out a move to the movable range.

Checking the software stroke limit enabled status
• In the monitor AxisName.Md.SwStrokeLimit_Override, the software stroke limit enabled/disabled status can be checked.
• AxisName.Md.SwStrokeLimit_Override is updated when turning the PLC READY[Y0] from OFF to ON and when starting
the axis operation.
• Since AxisName.Cd.SwStrokeLimit_Override is restricted by switching of the software stroke limit enabled/disabled status,
it performs import at start and updates AxisName.Md.SwStrokeLimit_Override.
AxisName.Pr.SwStrokeLimit_Target
1: Invalid (Disabled)
