9.3.8 Returning to the Restart Position

The axis is returned to the restart position after restart search is completed.
The method for returning to the restart position (manual/automatic) can be selected with the parameters "#1302 AutoRP".
0: Manual restart position return
1: Automatic restart position return
Operation method (manual restart position return)
(1) Turn the restart switch ON.
(2) Enter the manual (JOG/rapid traverse) mode.
(3) Move the axis in the restart return direction.
(4) When all axes have been returned, turn the restart switch OFF.
Note
(1) When the restart switch is ON, move the axis in the same direction as the restart direction. If moved in the reverse di-
rection, the operation error "M01 R-pnt direction illegal" occurs. If the tool needs to be retracted once, such as if the tool
is interfering with the workpiece, turn the restart switch OFF and retract the axis manually.
(2) After restart position return is completed, the axis cannot be moved if the restart switch is ON. If the axis is moved, the
operation error "M01 restart switch ON" occurs.
(3) If even one axis has not completed return to the restart position at cycle start, the error "M01 Restart pos. return incom-
plete" occurs. Note that if the axis has been returned to the restart position once and is not at the restart position during
cycle start, the alarm does not occur.
(4) If the axis to be returned to the restart position is a machine lock axis, the operation error "M01 program restart machine
lock" occurs. Release the machine lock before returning to the restart position.
(5) If the restart switch is turned to ON after the axis is returned to the restart position with the restart switch OFF, "PR" may
not be displayed. Return to the restart position after the restart switch is turned ON.
(6) After restart search had been completed, if the movement command is issued by MDI before automatic restart position
return has been started, the program error (P48) occurs. Perform the operation again after reset.
(7) After restart search had been completed, if the T command different from the program is issued by MDI before the
searched program has been started, the program error (P48) may occur. Perform the operation again after reset.
T commands which result in errors are shown below. (Only L system)
When "#1100 Tmove" = "0"
T command that selects a tool with different tool length/wear amount than the tool selected by the program.
When "#1100 Tmove" = "1"
A program error (P48) will not occur by T command.
When "#1100 Tmove" = "2"
T command that selects a tool with different wear amount than the tool selected by the program.
(8) After restart search had been completed, if the handle interruption is performed before the searched program has been
started, always the same operation as manual absolute ON is executed regardless of "Manual absolute" signal.
IB-1501453-C
The restart position and "RP" appear sequentially from
the axes that have been returned. The Restart remaining
distance is "0".
