Abstract
A device for determining a reference curve for a rotational position of a rotary component rotatable about an axis of rotation. An encoder disk is connected to the rotary component and is rotatable about the axis of rotation where the encoder disk is circular and has a periodic outer contour with periods. A beam source emits a measuring beam directed onto the periodic outer counter of the encoder disk. A control unit is connected to a sensor unit. Each of the periods of the periodic outer contour of the encoder disk are made up of a respective first function portion and a respective second function portion where the first function portion and the second function portion follow a monotonic progression and where one of the first function portion and the second function portion increases monotonically and the other of the first function portion and the second function portions decreases monotonically.
