Besides the six workpiece coordinate systems (standard workpiece
coordinate systems) selectable with G54 to G59, 48 additional workpiece
coordinate systems (additional workpiece coordinate systems) can be
used. Alternatively, up to 300 additional workpiece coordinate systems
can be used.

When a P code is specified together with G54.1 (G54), the corresponding
coordinate system is selected from the additional workpiece coordinate
systems (1 to 48).
A workpiece coordinate system, once selected, is valid until another
workpiece coordinate system is selected. Standard workpiece coordinate
system 1 (selectable with G54) is selected at power–on.

When an absolute workpiece zero point offset value is specified, the
specified value becomes a new offset value. When an incremental
workpiece zero point offset value is specified, the specified value is added
to the current offset value to produce a new offset value.
As with the standard workpiece coordinate systems, the following
operations can be performed for a workpiece zero point offset in an
additional workpiece coordinate system:
(1)The
OFFSET function key can be used to display and set a workpiece
zero point offset value.
(2)The G10 function enables a workpiece zero point offset value to be set
by programming (refer to
II–8.2.3).
