Figure 2-8 Phase 3: Traversing to the reference point
Phase 3: Start
At the end of phase 2 the machine axis travels at reference point creep velocity. Therefore,
as soon as phase 2 is completed successfully without an alarm, phase 3 is started without
interruption.
Initial situation
The encoder zero mark has been detected.
