A datum table saves positions on the workpiece. To use a datum table, you must activate it. Within an NC program, the datums can be called, e. g. to execute machining processes on several workpieces at the same position. The active row of the preset table serves as the workpiece preset in the NC program.

Description of function
The datums from a datum table are referenced to the current workpiece preset. The coordinate values from datum tables are only effective as absolute coordinate values.
- Datum tables can be used in the following situations:
- Frequent use of the same datum shift
- Recurring machining sequences on different workpieces
- Recurring machining sequences at different positions on the workpiece
Activating the datum table manually
A datum table can be activated manually for the Program Run operating mode.
In the Program Run operating mode, the Program settings window contains the Tables area. In this area, a datum table and both compensation tables can be selected in one selection window for running the program.
When activating a table, the control will highlight this table with the status M.

If the datum table is not stored in the same directory as the NC program, the complete path name must be defined. The Program settings window allows defining whether the control creates absolute or relative paths.
Settings in the Program workspace
- If you enter the datum table name manually, please note the following:
- If the datum table is stored in the same directory as the NC program, enter the file name only.
- If the datum table is not stored in the same directory as the NC program, enter the complete path.
