The circumferential slots are positioned around a full circle. The distance from one
circumferential slot to the next circumferential slot is always the same and is
calculated by the control.
The circumferential slots are positioned around a pitch circle. The distance from one
circumferential slot to the next circumferential slot can be defined using angle α2.
