Axis Coupling (900, 3-/4-Axis Only) – F 18/F 19
F 18 and/or F 19 allow you to sum 2 parallel axes on 1 axis display. This allows you to
move the coupled axes independently while the DRO automatically calculates the true
tool position. The following table lists which axes are summed by F 18 and F 19 for a 3-
axis DRO and a 4-axis DRO.
3-Axis DRO 4-Axis DRO
F 18 Axis 2 + Axis 3 Axis 3 + Axis 4
F 19 N/A Axis 1 + Axis 2
The DRO displays the summed axes in the message window.
