Phase-independent data
The following machine data and interface signals are independent with respect to the
individual phases of reference point approach:
● MD11300 $MN_JOG_INC_MODE_LEVELTRIGGRD (INC/REF in jog mode)
● MD34000 $MA_REFP_CAM_IS_ACTIVE (axis with reference cam)
● MD34110 $MA_REFP_CYCLE_NR (axis sequence for channel-specific reference point
approach)
● MD30240 $MA_ENC_TYPE (encoder type)
● MD34200 $MA_ENC_REFP_MODE (referencing mode)
● MD34310 $MA_ENC_MARKER_INC (interval between two reference marks)
● MD34320 $MA_ENC_INVERS (inverse measuring system)
● IS DB21, ... DBX1.0 ("Activate referencing")
● IS DB21, ... DBX33.0 ("Activate referencing")
Phase 1: Synchronize by overriding 2 reference marks
The following machine data and interface signals are relevant:
● MD34010 $MA_REFP_CAM_DIR_IS_MINUS (approach reference cam in minus direction)
● MD34040 $MA_REFP_VELO_SEARCH_MARKER (referencing velocity)
● MD34060 $MA_REFP_MAX_MARKER_DIST (maximum distance between 2 reference
marks)
● MD34300 $MA_ENC_REFP_MARKER_DIST (Reference mark distance)
● IS DB21, ... 30, DBX36.2 ("All axes to be referenced are referenced")
● IS DB31, ... DBX4.7/DBX4.6 ("Traversing keys plus/minus")
● IS DB31, ... DBX12.7 ("Reference point approach delay")
● IS DB31, ... DBX60.4, DBX60.5 ("Referenced/synchronized 1, 2")
Properties of phase 1:
● If the machine axis travels a distance defined in MD34300 $MA_REFP_MARKER_DIST
(max. distance from reference point) from the starting point without overriding two
reference marks, then the machine axis stops and Alarm 20004 "Reference Mark is
missing" is output.
Phase 2: Traversing to the target point
The following machine data and interface signals are relevant:
● MD34070 $MA_REFP_VELO_POS (end point positioning velocity)
● MD34090 $MA_REFP_MOVE_DIST_CORR (absolute offset)
● MD34100 $MA_REFP_SET_POS (target point)
● MD34330 $MA_REFP_STOP_AT_ABS_MARKER (with/without target point)
● IS DB31, ... DBX60.4, DBX60.5 ("Referenced/synchronized 1, 2")
