7.2.4 Changing Workpiece Coordinate System
The six workpiece coordinate systems specified with G54 to G59 can
be changed by changing an common workpiece zero point offset value
or workpiece zero point offset value.
Three methods are available to change an common workpiece zero
point offset value or workpiece zero point offset value.
(1) Inputting from the MDI panel (See Operation II-9.2.)
(2) Programming by G10 or G92
(3) Using the common data input function
An external workpiece zero point offset value can be changed by
input signal to CNC. Refer to machine tool builder’s manual for
details

- Changing by G10
G10 L2 Pp IP ;
p=0 : External workpiece zero point offset value
p=1 to 6: Workpiece zero point offset value correspond to
workpiece coordinate system 1 to 6
IP: For an absolute command (G90), workpiece zero point
offset for each axis.
For an incremental command (G91), value to be added
to the set workpiece zero point offset for each axis (the
result of addition becomes the new workpiece zero point
offset).
