Phase-independent data
The following machine data and interface signals are independent with respect to the
individual phases of reference point approach:
• MD11300 JOG_INC_MODE_LEVELTRIGGRD (INC/REF in jog mode)
• MD34000 REFP_CAM_IS_ACTIVE (axis with reference cam)
• MD34110 REFP_CYCLE_NR (Axis sequence for channel-specific reference point
• MD30240 ENC_TYPE (encoder type)
• MD34200 ENC_REFP_MODE (Referencing mode)
• IS: DB21, ... DBX1.0 ("Activate referencing")
• IS: DB21, ... DBX33.0 ("Referencing active")
Phase 1: Traversing to the reference cam
The following machine data and interface signals are relevant:
• MD34010 REFP_CAM_DIR_IS_MINUS (approach reference cam in negative direction)
• MD34020 REFP_VELO_SEARCH_CAM (reference cam approach velocity)
• MD34030 REFP_MAX_CAM_DIST (Maximum distance to the reference cam)
• MD34092 REFP_CAM_SHIFT (electr. cam offset, incremental measuring systems with
• IS: DB21, ... DBX36.2 ("all axes with obligatory reference point are referenced")
