Basic machine coordinate system
(2) By commanding G92, the absolute value (workpiece) coordinate system and current position display value can be preset
in the command value without moving the machine.
(1) After the power is turned on, the first reference position return will be done with dog-type, and when completed, the
coordinate system will be set automatically. (Automatic coordinate system setting)
(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 position return while the coordinate system is deviated.
(2) After that, command G92G53X0Y0Z0;. With this command, the workpiece coordinate
position and current position will be displayed, and the workpiece coordinate system
will be preset to the offset value.
