Position display in a tilted system
The positions displayed in the status window (ACTL. and NOML.)
are referenced to the tilted coordinate system.
In the optional machine parameter CfgDisplayCoordSys (no.
127501) you can specify the coordinate system in which the status
display shows an active datum shift.
Limitations on working with the tilting function
The Actual-position capture function is not allowed if the Tilt
working plane function is active
PLC positioning (determined by the machine tool builder) is not
possible.
