Writing the measured values from touch probe 
cycles in datum tables
With the ENTER IN DATUM TABLE soft key, the TNC can write the 
values measured during a touch probe cycle in a datum table:
U
Select any probe function
U
Enter the desired coordinates of the datum in the appropriate input 
boxes (depends on the touch probe cycle being run)
U
Enter the datum number in the Number in table= input box
U
Enter the name of the datum table (complete path) in the Datum 
table
input box
U
Press the ENTER IN DATUM TABLE soft key. The TNC saves the 
datum in the indicated datum table under the entered number
This function is active only if you have datum tables active 
on your TNC (bit 3 in Machine Parameter 7224.0 =0).
Use this function if you want to save measured values in 
the workpiece coordinate system. If you want to save 
measured values in the machine-based coordinate system 
(REF coordinates), press the ENTER IN PRESET TABLE 
soft key (see “Writing the measured values from touch 
probe cycles in the preset table” on page 454).
Note that during an active datum shift the TNC always 
bases the probed value on the active preset (or on the 
reference point most recently set in the Manual operating 
mode), although the datum shift is included in the position 
display.
