2.4 Referencing with incremental measurement systems
Basic logic functions: Reference Point Approach (R1)
Function Manual, 11/2006, 6FC5397-0BP10-2BA0
15
Zero must be entered in the following machine data for machine axes without a reference
point cam:
MD34000 $MA_REFP_CAM_IS_ACTIVE (Axis with reference cam) = 0
Phase 1 is now complete. Reference point approach is continued with Phase 2.
Phase 1: Features
• Feed override active.
• Feed stop (channelspecific and axisspecific) is active.
• NC-STOP and NC-START are active.
• The machine axis is stopped if the reference cam does not arrive within the
parameterized distance:
MD34030 $MA_REFP_MAX_CAM_DIST (max. distance to reference cam)
DB31, ... DBX12.7 (reference point approach delay) = 1
