10.4.6 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:
MD9424 $MM_MA_COORDINATE_SYSTEM (coordinate system for actual value display)
Value Significance
0 Actual-value display in relation to the WCS
1 Actual-value display in relation to the SZS
Note
Display of the current coordinate system
When "Actual-value display in relation to the SZS" is active, the WCS is still displayed on the
HMI operator interface as the coordinate system to which the actual-value display relates.
