Edit a pocket table in a Program Run operating mode.
In a program run mode you can select the active datum table. Press
the DATUM TABLE soft key. You can then use the same editing
functions as in the Programming and Editing mode of operation.
Configuring the datum table
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.
If you do not wish to define a datum table for an active axis, press the
NO ENT key. The TNC then enters a dash in the corresponding
column.
To leave a datum table
Select a different type of file in file management and choose the
desired file.

The actual position values are referenced to the active (shifted)
datum.
n All of the position values shown in the additional status display are
referenced to the machine datum, whereby the TNC accounts for
the manually set datum.
