Activating a datum from the preset table in the Manual Operation
mode

Select the Manual Operation mode.

Display the preset table.

Select the datum number that you want to activate, or

Activate the preset.

Confirm activation of the datum. The TNC sets the
display and—if defined—the basic rotation.

Leave the preset table.

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 247)” on page
340).

When activating a datum from the preset table, the TNC
resets the active datum shift, mirroring, rotation and
scaling factor.

However, a coordinate transformation that was
programmed in Cycle 19 Tilted Working Plane, remains
active.
