Activating a datum from the preset table in the Manual Operation

Select the datum number that you want to activate, or

Activating a datum from the preset table in an NC program

To activate datums from the preset table during program run, use
Cycle 247. In Cycle 247 you define only the number of the datum that
you want to activate (see “DATUM SETTING (Cycle G247)” on page
461).

When activating a datum from the preset table, the TNC
resets the active datum shift.

However, a coordinate transformation that was
programmed in Cycle G80 Tilted Working Plane, or
through the PLANE function, remains active.

If you activate a preset that does not contain values in all
coordinates, the last effective reference point remains
active in these axes.
