Resetting all axes to zero
You can reset all axes to zero by pressing a single key. The last actual
position then becomes the relative datum and is not stored (incremen-
tal positioning), and the status display shows “– –” instead of the tool
number. Any tool datums already set remain in memory. You can
activate these by entering the corresponding tool number.
