Detailed description
2.3 Coordinate systems
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
0
1
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.
