Fig. 2-5 Synchronization with falling reference cam signal edge
Case 2: Synchronization with rising reference cam edge
During synchronization with rising reference cam edge, the machine axis accelerates to the
assigned reference point approach velocity:
MD34020 $MA_REFP_VELO_SEARCH_CAM (reference point approach velocity)
along the assigned reference point approach direction (traversing direction of Phase 1):
MD34010 $MA_REFP_CAM_DIR_IS_MINUS (approach reference point in minus direction).
After the reference cam is exited:
DB31, ... DBX12.7 (deceleration of reference point approach) = 0
the machine axis is decelerated to a standstill.
Then, the machine axis moves back on the reference cam at the assigned reference point
creep velocity:
MD34040 $MA_REFP_VELO_SEARCH_MARKER
(reference point creep velocity).
After the reference cam is reached:
DB31, ... DBX12.7 (deceleration of reference point approach) = 1
the machine axis waits for the next encoder zero mark.
As soon as the encoder zero mark is detected, Phase 2 comes to an end. The machine axis
continues at constant velocity and reference point approach is continued with phase 3.
