Example of actuator with counterclockwise rotation:
When referencing in the CLOSED position, the actuator first travels a certain distance
into the working range (toward the OPEN position). Then, it travels to a position
representing maximum -7.7°, thereby crossing the reference mark for the fist time. Then,
the actuator moves in the other direction again and detects the inner ramp of the
reference mark. This is the reference point used by all positions. If the reference point is
parameterized in the OPEN position, referencing takes place in a mirror-symmetrical
manner. In that case, the actuator first travels into the working range (toward the OPEN
position). Then, it crosses the reference mark and travels to a position representing
maximum 110.6°, then back to the inner ramp of the reference mark.
