325
Before the machine axis travels over the parameterized number of reference marks, it
touches the reference cam. It is then reversed and reference mark search is restarted in the
opposite direction.
Once the number of reference markers set by means of parameter assignment has been
crossed, the machine axis is stopped again and the actual value system of the machine axis
is synchronized to the absolute position calculated by the NC.
Plausiblity check of the reference mark distance
An error occurs if, during reference point traversing for two subsequent reference marks, the
NC determines a distance greater than twice the parameterized reference mark distance.
MD34300 ENC_REFP_MARKER_DIST (reference marker distance)
The machine axis will then traverse in opposite direction at half the parameterized reference
point creep velocity (MD34040) and the search for reference mark is restarted.
If a faulty reference mark distance is detected again, the machine axis is stopped and the
reference point traversing is aborted (alarm 20003 "fault in the measuring system").
Abort criterion
If the parameterized number of reference marks is not detected within the parameterized
distance, the machine axis is stopped and reference point traversing is aborted.
MD34060 REFP_MAX_ MARKER_DIST (max. distance to the reference marker)
Features of phase 1
After phase 1 is successfully completed, the actual value system of the machine axis is
synchronized.
18.3.5
Phase 2: Travel to fixed stop
Phase 2: Start
Phase 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 of
reference marks.
●
The actual value system of the machine axis is synchronized.
