Abort criterionIf the parameterized number of reference marks is not detected within the parameterizeddistance, the machine axis is stopped and reference point traversing is aborted.MD34060 $MA_REFP_MAX_ MARKER_DIST (max. distance to the reference mark)Features of Phase 1After Phase 1 is successfully completed, the actual value system of the machine axis issynchronized.15.6.5 Phase 2: Traversing to the target pointPhase 2: StartPhase 2 is automatically started when Phase 1 has been completed without an alarm.Initial situation:● The machine axis is positioned directly behind the last of the parameterized number ofreference marks.● The actual value system of the machine axis is synchronized.Phase 2: SequenceIn Phase 2, the machine axis completes reference point approach by traversing to a definedtarget position (reference point). This action can be suppressed in order to shorten thereference point approach:MD34330 $MA_STOP_AT_ABS_MARKER = Value Meaning0 Travel to target position1 No travel to target positionTravel to target position (normal case)The machine axis accelerates to the parameterized reference point position velocity andtravels to the parameterized target point (reference point):MD34070 $MA_REFP_VELO_POS (reference point positioning velocity)MD34100 $MA_REFP_SET_POS (reference point value)The machine axis is referenced. To identify this, the NC sets an interface signal for themeasuring system that is currently active:DB31, ...
