(2) Restrictions
A pulse generator with a zero signal is required. When using a pulse generator without a zero signal, generate a
zero signal using an external signal.
(3) Precautions during operation
• An error "Start at OP (error code: 201)" will occur if another machine OPR is attempted after a machine OPR
completion when the OPR retry function is not set ("0" is set in "[Pr.48] OPR retry").
• Machine OPR carried out from the near-point dog ON position will start at the "[Pr.47] Creep speed".
• The near-point dog must be ON during deceleration from the OPR speed "[Pr.47] Creep speed". The
workpiece will continue decelerating and stop if the near-point dog is turned OFF before it has decelerated to
the creep speed, thus causing an error "Dog detection timing fault (error code: 203)".
• 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.
