Abstract
The disclosure relates to a method for operating a positioning actuator system with an electronically commutated actuator drive for driving an actuator element, having the following steps: non-volatile storage of a position information item of the actuator element or of a rotor of the actuator drive which was detected last as a reference position before the positioning actuator system is switched off; in the case of switching on of the positioning actuator system retrieval of the reference position and actuation of the actuator drive by energizing the actuator drive in accordance with a space phasor which is dependent on the reference position. The object is to make available an improved method for releasing blockage of an actuator element or actuation after activation of a motor system with a maximum actuating torque. For positioning actuators with commutated motors such as, for example, synchronous motors.
