You can define a datum shift by selecting a datum number from a
datum table with the TRANS DATUM TABLE function. Proceed as follows

Select the menu for defining various plain-language

functions.

Select transformations.

Select datum shifting with TRANS DATUM.

Press the arrow key to move to TRANS AXIS.

Select datum shifting with TRANS DATUM TABLE.

If desired, enter the name of the datum table from

which you want to activate the datum number, and
confirm with the ENT key. If you do not want to define
a datum table, confirm with the NO ENT key.

Enter the line number to be activated by the TNC, and

table with status M selected in one of the Program Run
modes.
