- This alternating start-stop movement of the rotor shaft 5 and / or the brake disk 20 and the output shaft 11 provides for the first time a fine opportunity to approach the TARGET position. Furthermore, in this case the elasticity of the drive train 2 or of the transmission 10 can be used, so that the rotor and the rotor shaft 5 move continuously to the desired position, but the output shaft 11 performs an alternating start-stop movement. If the receptacle 15 of the locking disc 14 is aligned with the locking pin 16, and the rotor shaft 5 is in the desired position, the control unit 100 starts the actual locking operation by the locking means 13 are approached. Specifically, the locking pin 100 is moved out of the bolt guide 17 and is inserted into the aligned receptacle 15 in the locking disc 14.
