DBX60.5 Referenced/synchronized 2
Edge evaluation:
Signal state 1 or Axes:
edge change
When being referenced, if the machine axis has reached the reference point (incremental measuring
0 → 1
systems) or the target point (for length measuring system with distance-coded reference marks),
then the machine axis is referenced and the following interface signal is set:
DB31, ... DBX60.5 (referenced/synchronized 2)
(depending on which position measuring system is active when referencing).
Spindles:
After power-on, a spindle is synchronized the latest after one spindle revolution (360 degrees) (the
zero mark passed or the Bero responded).
Signal state 0 or The machine axis/spindle with position measuring system 2 is not referenced/synchronized.
edge change
Axes:
1 → 0
Alarm 21610 was output.
Spindles:
Encoder limit frequency exceeded.

DBX71.4 POS_RESTORED 1
Edge evaluation:
Signal state 1 or If MD34210 $MA_ENC_REFP_STATE is set to a value of 3, the last axis position buffered before
edge change switch off is restored in distance-coded, incremental measuring systems. Referencing does not take
0 → 1 place automatically. Position measuring system 1 is in "Position restored" state.
Signal state 0 or The machine axis/spindle with position measuring system 1 is not restored.

DBX71.5 POS_RESTORED 2
Edge evaluation:
Signal state 1 or If MD34210 $MA_ENC_REFP_STATE is set to a value of 3, the last axis position buffered before
edge change switch off is restored in distance-coded, incremental measuring systems. Referencing does not take
0 → 1 place automatically. Position measuring system 2 is in "Position restored" state.
Signal state 0 or The machine axis/spindle with position measuring system 2 is not restored.
