• Validate the OPR retry function (set value: 1). (Refer to
Section 13.2.1).
• Move the work piece from the current position (on OP) using
the manual control operation (refer to Chapter 11), then carry
out a machine OPR again.

• Calculate the movement distance using a speed limit, OPR
speed, and deceleration time, and set the movement amount
after near-point dog ON so that the distance becomes a
deceleration distance or longer.
• Lower the OPR speed.
• Adjust the near-point dog position so that the movement
amount after near-point dog ON becomes longer. (Refer to

• Execute OPR again.
• When the servo parameter "Function selection C-4 (PC17)"
is changed to "1: Not need to pass servo motor Z-phase after
power on", transfer the parameter from the Simple Motion
module to the servo amplifier and turn the power supply of
the servo amplifier OFF. Then, turn it ON and execute OPR
again.
