Error name Operation status at error occurrence
■Description
When the OPR retry invalid is set, the near-point
dog machine OPR is started with the OPR complete
flag turned ON.
■Operation status at error occurrence
The machine OPR does not start.
■Description
The near-point dog signal is turned OFF during the
deceleration from an OPR speed to a creep speed
by the near-point dog machine OPR.
■Operation status at error occurrence
The system stops with the setting (deceleration
stop/sudden stop) of the detailed parameter 2
Sudden stop selection (stop group 3). (Note that the
deceleration stop only occurs during the manual
pulse generator operation.)
■Description
The zero signal is turned OFF during the
deceleration from an OPR speed to a creep speed
by the stopper method 2)-OPR.
■Operation status at error occurrence
The system stops with the setting (deceleration
stop/sudden stop) of the detailed parameter 2
Sudden stop selection (stop group 3). (Note that the
deceleration stop only occurs during the manual
pulse generator operation.)
■Description
A dwell time is passed during the deceleration from
a creep speed to a OPR speed by the stopper
method 1)-OPR.
■Operation status at error occurrence
The system stops with the setting (deceleration
stop/sudden stop) of the detailed parameter 2
Sudden stop selection (stop group 3). (Note that the
deceleration stop only occurs during the manual
pulse generator operation.)

■Action
• Validate the OPR retry function (set value: 1).
( Page 510, Section 12.2.1)
• Move the workpiece from the current position
(on OP) using the manual control operation
( Page 479, CHAPTER 11), then carry out
a machine OPR again.
