Abstract
A method for operating an electromagnetic actuator () with an actuating pin () is proposed which comprises the following steps: —determining a pin actuation actual dead time (t), during which the magnetic armature () is substantially immobile while a magnetic coil () is supplied with current, wherein the actual dead time ends with the current break-in at the magnetic coil, as a result of counter induction of the magnetic armature overcoming the magnetic force threshold; —determining, before a subsequent pin actuation, the starting time of the magnetic coil current supply, wherein the starting point of the current is advanced compared with that of the target movement start of the pin out of the actuator housing () and the determined actual dead time.
