The user can choose from set workpiece coordinate systems as described
below.
(1)Selecting a workpiece coordinate system set by G92 (G50) or
automatic workpiece coordinate system setting
Once a workpiece coordinate system is selected, absolute commands
work with the workpiece coordinate system.
(2)Choosing from six workpiece coordinate systems set using the
MDI panel
By specifying a G code from G54 to G59, one of the workpiece
coordinate systems 1 to 6 can be selected.
G54 Workpiece coordinate system 1
G55 Workpiece coordinate system 2
G56 Workpiece coordinate system 3
G57 Workpiece coordinate system 4
G58 Workpiece coordinate system 5
G59 Workpiece coordinate system 6
Workpiece coordinate system 1 to 6 are established after reference
position return after the power is turned on. When the power is turned
on, G54 coordinate system is selected.
The six workpiece coordinate systems specified with G54 to G59 can be
changed by changing an external workpiece zero point offset value or
workpiece zero point offset value.
Three methods are available to change an external workpiece zero point
offset value or workpiece zero point offset value.
(1) Inputting from the MDI panel
(2) Programming by G10 or G92 (G50)
(3) Using external data input (refer to 15.2)
