15.5.5 Phase 3: Traversing to the reference point
Phase 3: Graphic representation
Figure 15-9 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
ref
to be covered is calculated from the sum of the reference point distance plus reference point offset:
MD34080 $MA_REFP_MOVE_DIST (reference point distance)
MD34090 $MA_REFP_MOVE_DIST_CORR (reference point offset)
