Referencing sequence with incremental measuring system (example):
Characteristics of traversing to the reference point cam (phase 1)
● The feedrate override and feedrate stop is in effect.
● The machine axis can be stopped/started.
● The cam must be reached within the traversing distance in MD34030 REFP_MAX_CAM_DIST, otherwise a
corresponding alarm is triggered.
● The machine axis must come to a halt at the cam, otherwise a corresponding alarm is triggered.
Characteristics when synchronizing with the zero pulse (phase 2)
● Feedrate override is not active. Feedrate override 100% is active. Termination occurs at feedrate override 0%.
● Feedrate stop is active, the axis comes to a halt and a corresponding alarm is displayed.
● The machine axis cannot be stopped and restarted with NC stop/NC start.
● Monitoring of the zero mark is active with MD34060 REFP_MAX_MARKER_DIST.
Characteristics of traversing to the reference point (phase 3)
● The feedrate override and feedrate stop is in effect.
● The machine axis can be stopped and re-started with NC stop/NC start.
● If reference point offset is smaller than the braking distance of the machine axis from the reference point positioning
velocity to stop, the reference point is approached from the opposite direction.
