Workpiece coordinate system offset
By using variable numbers #5201 to #532n, it is possible to read out the workpiece coordinate
system offset data or to substitute values.
(Note) The number of axes which can be controlled differs according to the specifications.
The last digit of the variable No. corresponds to the control axis No.

#5201=0 #5202=0;
This is an example where the external workpiece offset values are added to the workpiece
coordinate (G54, G55) system offset values without changing the position of the workpiece
coordinate systems.
