Example: Drilling by traversing to display value zero with incremental
positioning
Enter the coordinates in incremental dimensions. These are indicated
in the following (and on the screen) with a preceding I. The datum is
the workpiece zero.
Hole
1 at: X = 20 mm / Y = 20 mm
Distance from hole 2 to hole 1 : XI = 30 mm / YI = 30 mm
Hole depth: Z = –12 mm
Operating mode: INCREMENTAL
Press the SET/ZERO soft key to be in the Set mode.
Press the X axis key.
Enter nominal position value for hole 1: X = 20 mm,
and ensure no tool radius compensation is active.

Enter nominal position value for hole 1: Y = 20 mm.
Ensure no tool radius compensation is showing.
Press the DOWN ARROW key.
Enter the nominal position value for the hole depth:
Z = –12 mm. Press Enter.
