How to select a workpiece coordinate system

As described below, the user may choose from predefined workpiece coordinate
systems.
1. G92 (G50)
Absolute commands work with the workpiece coordinate system once a work-
piece coordinate system has been selected.
2. Selecting from workpiece coordinate systems previously set up by using the
HMI panel.
A workpiece coordinate system can be selected by determining a G code from
G54 to G59, and G54 P{1...100}.
Workpiece coordinate systems are set up subsequently to reference position
return after power--on. The default coordinate system after power--on is G54.
