Phase 3: Traversing to the reference point

Phase 3: Graphic representation
Figure 10-9 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.
Phase 3: Sequence
The machine axis moves at the assigned reference point positioning velocity:
MD34070 $MA_REFP_VELO_POS (reference point positioning velocity)
from the encoder zero mark detected in Phase 2 to the reference point.
The path s
reference point offset:
MD34080 $MA_REFP_MOVE_DIST (reference point distance)
MD34090 $MA_REFP_MOVE_DIST_CORR (reference point offset)
