■OPR retry operation when the workpiece is outside the range between the upper/lower limits
• When the direction from the workpiece to the OP is the same as the direction set in [Pr.44] OPR direction, the normal
machine OPR is performed. The following is an example of when [Pr.44] OPR direction is set to 0: Forward direction.
Machine OPR start
[Pr.44] OPR direction
Lower limit
• When the direction from the workpiece to the OP is the opposite direction from the direction set in [Pr.44] OPR direction, the
operation performs the deceleration stop when Near-point dog signal is turned off, and performs the machine OPR in the
direction set in [Pr.44] OPR direction. The following is an example of when [Pr.44] OPR direction is set to 0: Forward
direction.
Lower limit
• When [Pr.44] OPR direction is set to 0: Forward direction, check that the limit switch placed in the OPR
direction works as the upper limit.
• When [Pr.44] OPR direction is set to 1: Reverse direction, check that the limit switch placed in the OPR
direction works as the lower limit.
• Incorrect wiring of these limit switches may cause improper OPR retry operation.
• If any malfunction is identified, check and correct the wiring and the setting in [Pr.6] Rotation direction
setting.
