7.2.5 Adding Workpiece Coordinate Systems (G54.1)
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.
Format
G54.1 Pn ;
n = 1 to 48
Explanation
- Selecting the additional workpiece coordinate systems
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.
G54.1 P1 Additional workpiece coordinate system 1
G54.1 P2 Additional workpiece coordinate system 2

G54.1 P48 Additional workpiece coordinate system 48
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-15).
3) A custom macro allows a workpiece zero point offset value to be
handled as a system variable.
4) Workpiece zero point offset data can be entered or output as
external data.
5) The PMC window function enables workpiece zero point offset
data to be read as program command modal data.
- Setting of the workpiece origin offset in an additional workpiece coordinate system
(G10)
When the specified workpiece origin offset is an absolute value, it is
assumed to be the new offset. When it is an incremental value, the sum
of the current offset and the specified offset is assumed to be the new
offset.
Limitation
A P code must be specified after G54.1 (G54). If G54.1 is not followed
by a P code in the same block, additional workpiece coordinate system
1 (G54.1P1) is assumed.
