Abstract (en)

[origin: WO0079548A2] In order to control an actuator, the following steps are carried out in the given sequence when an armature plate is moved from a position in which it is resting against a contact surface to a position in which it is resting against a contact surface of an electromagnet. A predetermined amount of electric energy is supplied to the coil. The coil is directed into an operating state of the freewheel until a first condition is fulfilled. A predetermined second amount of electric energy is supplied to the coil before the armature plate is moved to a position in which it rests against the contact surface of the electromagnet. The coil is directed into an operating state of the freewheel until a second condition is fulfilled whose fulfillment indicates that the armature plate (116) is resting against the contact surface of the electromagnet.
