2.4.2 Switching the coordinate system (MKS/WKS)
The coordinates in the actual value display are relative to either the
machine coordinate system or the workpiece coordinate system. The
machine coordinate system (MKS), in contrast to the workpiece
coordinate system (WKS), does not take into consideration any zero-
point offsets (see Sec. "Zero-point Offsets"). By default, the workpiece
coordinate system is set as a reference for the actual value display.
