Datum setting on machines with rotary tables
If you use a rotary table to align the workpiece, for example with
probing cycle 403, you must set the table position value to zero after
alignment and before setting the datum in the linear axes X, Y and Z.
Otherwise, the TNC generates an error message. Cycle 403 provides
you with an input parameter for this purpose (see User’s Manual for
Touch Probe Cycles, "Basic Rotation Compensation via Rotary Axis").
Datum setting on machines with spindle-head
changing systems
If your machine is equipped with a spindle head changer, you should
use the preset table to manage your datums. Datums saved in preset
tables account for the active machine kinematics (head geometry). If
you exchange heads, the TNC accounts for the new head dimensions
so that the active datum is retained.
Position display in a tilted system
The positions displayed in the status window (ACTL. and NOML.) are
referenced to the tilted coordinate system.
Limitations on working with the tilting function
 The probing function for basic rotation is not available if you have
activated the working plane function in the Manual Operation mode.
 The actual-position-capture function is not allowed if the tilted
working plane function is active.
 PLC positioning (determined by the machine tool builder) is not
possible.
