Configuring the datum table
If you do not wish to define a datum for an active axis, press
the DEL key. Then the TNC clears the numerical value from the
corresponding input field.
You can change the properties of tables. Enter the
code number 555343 in the MOD menu. The TNC
then offers the EDIT FORMAT soft key if a table is
selected. When you press this soft key, the TNC
opens a pop-up window where the properties are
shown for each column of the selected table. Any
changes made only affect the open table.
To exit a datum table
Select a different type of file in file management and choose the
desired file.
After you have changed a value in a datum table, you
must save the change with the ENT key. Otherwise
the change may not be included during program run.
Status displays
In the additional status display, the TNC shows the values of the
active datum shift.
