• If the zero signal is input before the workpiece stops at the stopper, the workpiece will stop at that position,
and that position will become the OP. At this time, an error will not occur.

• The near-point dog must be turned ON until it presses against the stopper. If any range that the near-point is
turned OFF exists until it presses against the stopper, executing the machine OPR from the area leads it to
be pressed against the stopper at ORR speed.
• Machine OPR started while the near-point dog is ON will start at the "[Pr.47] Creep speed".
• When a machine OPR is stopped with the stop signal, perform a machine OPR again. If the restart
command is turned ON after a stop with the stop signal, an error "OPR restart not possible" (error code: 209)
occurs.
