Settable zero system (SZS)

Settable zero system (SZS)
The "settable zero system" (SZS) is the workpiece coordinate system WCS with a
programmable frame (viewed from the perspective of the WCS). The workpiece zero is defined
by the settable FRAMES G54 to G599.

Programmable offsets act on the "settable zero system". All programmable offsets refer to the
"settable zero system".
WCS actual-value display in WCS or SZS
The actual values of the axes in the machine coordinate system (MCS) or the WCS can be
displayed on the HMI operator interface. For displays in WCS, the actual values can also be
displayed in relation to the SZS. The corresponding parameterization takes place through the
machine data:
