Abstract
A rotating actuator includes a shaft (24) and a mechanical stop device (23) for generating a stop to limit the rotation of the shaft in a direction of rotation. The stop device acts upon the shaft to prevent the shaft from rotating further in the direction of rotation by blocking the shaft using a stop device acting mechanically on the shaft while enabling rotation of the shaft in a direction of rotation counter to the stop with slip in a stop arrangement. The slip is configured such that movement of the shaft in the direction of rotation counter to the stop is detectable. The stop device may include two independently triggered, mechanical stop devices. One stop device acts as a stop for limiting the rotation of the shaft to the right, and the other stop device acts as a stop for limiting the rotation of the shaft to the left.
