Referencing with distance-coded reference marks can be divided into two phases:
• Phase 1: Travel across the reference marks with synchronization
• Phase 2: Traveling to a fixed destination point

Phase 1: Travel across the reference marks with synchronization
Phase 1: Start
For information on starting reference point approach, refer to "Axis-specific referencing" and "Channel-specific
referencing."
reference cam
In measuring systems with distance-coded reference marks, reference cams are not required for the actual
referencing action. For functional reasons, however, a reference cam is required for channel-specific reference
point approach and reference point approach from the part program (
G74
) before the traversing range end of the
machine axis.
