10.1.2 Coordinate System Setting
M720VW
M system ○
L system ○
Among the workpiece coordinate systems with the G92, the program coordinate system (the programmed
zero point) can be changed.
When a coordinate system setting is assigned using the G92 command, the G92 offset amount is applied so
that the machine position in the current workpiece coordinate system is set to the coordinate position
assigned by the G92 command, as shown in the figure below, and the workpiece coordinate systems are
shifted accordingly. The machine does not run, and all the workpiece coordinate systems from G54 to G59
referenced to the machine coordinate system (or the external workpiece coordinate system if the external
workpiece coordinate offset has been set) are shifted.
Offset of coordinate system by G92 coordinate system setting
Example where W1 is shifted to new W1 when the machine was at the position (x0, y0) above W1 and the G92 Xx1
Yy1; command was assigned when the workpiece coordinate system W1 is modal
(external workpiece coordinate system offset = 0; interrupt amount offset = 0)

(b) G92 offset amount
(c) Machine position
(d) New W1
The shifted coordinate system is returned to its original position by dog-type reference position return or the
program.
