9 Machining a Workpiece
Automatic restart position return
If the parameter "#1302 AutoRP" is set to "1", each axis returns to the restart position with dry run at cycle start. Machining
restarts after returning. The order that the axes return follows parameter "#2082 a_rstax".
Note
(1) Manually move the axis to a position where the tool does not interfere with the workpiece before starting the cycle.
(2) Even if the parameter "#1302 AutoRP" is to "1", the axes can be returned manually to the restart position by turning the
restart switch ON. In this case, move the axes in the order of manual restart position return -> automatic restart position
return. After completing automatic restart position return, if the operation is stopped temporarily and the restart switch
is turned ON, the operation error "M01 restart switch ON" occurs.
(3) Once the axis has been manually returned to the restart position, if it is moved from the restart position, it will not return
to the restart position even if automatic restart position return is executed.
(4) The axis for which parameter "#2082 a_rstax" is set to "0" does not return to the restart position. Note that if "0" is set
for all axes, all axes simultaneously return to the restart position. Designate the axes in part system units. If the axis for
which parameter "#2082 a_rstax" is set to "0" has not completed manual restart position return when automatic restart
position return is started, an error occurs. The error "M01 Restart pos. return incomplete" is displayed.
(5) After automatic restart position return had been started, if the automatic start is executed during MDI mode before not
all axes have yet to complete automatic restart position return, the error "M01 Restart pos. return incomplete" occurs.
(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. When
manual interruption is executed to the automatic restart position return completed axis, the axis never returns the auto-
matic restart position again.
(9) When an axis moved to return is operated manually, the axis cannot return to correct position.
