(Note) If the workpiece coordinate system deviated because the axis is moved manually when
the manual absolute position switch is OFF, etc., the workpiece coordinate system can be
corrected with the following steps.
(1) Execute reference point return while the coordinate system is deviated.
(2) After that, command G92G53X0Y0Z0;. With this command, the workpiece coordinate
