In this case, the return movement path will be as shown below.
1) X axis and Y axis move simultaneously.
2) Z axis and C axis move simultaneously.
3) All axes move simultaneously.
4) Z axis moves.
5) X axis, Y axis and C axis move

interruption point will be canceled. The halted or stopped automatic operation will be reset and
finished.
amount will be invalidated when the reference point return is completed. Thus, if the tool is
compensated before tool retract , when the tool is returned after reference point return, the
path will shift by the tool compensation amount at the block following the block containing the
interruption point.
Thus, if the operation mode is changed to reference point return during tool retract return, a
warning will occur.

Interruption point
• If the reference point return mode is selected during the tool
retract return mode, "OPW168 Ref.pnt ret cancel tool offset"
will occur.
• When the operation mode is changed to a mode other than
reference point return before the axis returns to the
reference point.
• When the tool return is completed.
• When reset 1 is input.
• When emergency stop occurs.
