The following machine data and interface signals are important:
MD34070: REFP_VELO_POS (reference-point positioning velocity)
MD34080: REFP_MOVE_DIST (reference point distance to the zero mark)
MD34090: REFP_MOVE_DIST_CORR (reference-point offset additive)
MD34100: REFP_SET_POS (reference point value).
IS: DB31, ... DBX2.4, 2.5, 2.6, 2.7 ("Reference point values 1...4")
IS: DB31, ... DBX60.4, DBX60.5 ("Referenced/synchronized 1, 2").
Properties of phase 3:
Feed override (the feed override switch) is active.
Feed stop (channel-specific and axis-specific) is active.
The machine axis can be stopped and started again using NC Stop/NC
