Furthermore, all work coordinate system can be offset with a common value. It can also be entered
in setting mode.
9.2.2 Selecting the Work Coordinate System
The various work coordinate system can be selected with instructions G54...G59.
G54........work coordinate system 1
G55........work coordinate system 2
G56........work coordinate system 3
G57........work coordinate system 4
G58........work coordinate system 5
G59........work coordinate system 6
They are modal functions. Their selection before a reference point return is ineffective. After a
reference point return, work coordinate system
1 (G54) will be selected.
The absolute coordinate data of the
interpolation blocks will be taken into account
by the control in the current work coordinate
system.
For example, the instruction
G56 G90 G00 X60 Y40
will move the system to point X=60, Y=40 of
work coordinate system 3.
