Phase 1: Start
For information on starting reference point approach, refer to "Axis-specific referencing" and
"Channel-specific referencing."
Phase 1: Sequence
In phase 1, depending on the position of the machine axis with reference to the homing cam,
we distinguish between three cases:
1. The machine axis is positioned before the reference cam
2. The machine axis is positioned on the reference cam
3. The machine axis has no reference cam
