With the function „Actual position capture“ the TNC
stores the position of that axis in the header of the table
which is above the marked value (not TNC 410).
Configuring datum tables (not TNC 410)
On the second and third soft-key rows you can define for each
datum table the axes for which you wish to set the datums. In the
standard setting all of the axes are active. If you wish to exclude an
axis, set the corresponding soft key to OFF. The TNC then deletes
that column from the datum table.
To leave a datum table
Select a different type of file in file management and choose the
desired file.
