10.5 Parameterize axis data
• IS: DB31, ... DBX12.7 ("Reference point approach delay") = 0
• MD34060 REFP_MAX_MARKER_DIST (max. distance to the reference mark)
Phase 3: Approach reference point
The following machine data and interface signals are relevant:
• MD34070 REFP_VELO_POS (reference point positioning velocity)
• MD34080 REFP_MOVE_DIST (reference point distance to 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 value 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.
• NC-Stop/NC-Start are active.
