10.3.1 Reference travel
Reference travel means that 2 different reference travels are performed, aimed at un-
ambiguously determining the actuators’ permissible working range. This prevents the
actuators from traveling to a range outside the optical feedback system or against a me-
chanical stop should a power failure during referencing occur. Parameter 611 must be
set depending on the mechanical construction and the type of actuator used. In the case
of reference travel type 1, the SQM33... and SQN13... actuators first travel 10° in coun-
terclockwise direction, independent of the selected direction of rotation, the type of ac-
tuator, and the set reference point. The SQN14... first travels 10° in clockwise direction.
