Flying referencing
The converter corrects its position actual value while traversing and reduces errors, e.g.
caused by wheel slip or a gear ratio that has not been precisely set.
Example: A pallet on a roller conveyor must be stopped at a specific position. However, the
exact position of the pallet on the conveyor is only known when a sensor is passed.

The converter takes the reference point coordinate as the new axis position.
