Datum table

Application

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

Danger of collision!
The control does not consider the changes made to a datum table or compensation table until the values have been saved. You need to activate the datum or compensation value in the NC program again; otherwise, the control will continue using the previous values.
  1. Make sure to confirm any changes made to the table immediately (e.g., by pressing the ENT key)
  2. Activate the datum or compensation value in the NC program again
  3. Carefully test the NC program after changing the table values
