Abstract (en)
[origin: EP1005051A2] The method involves determining the switching time point at which a movable element in the electromagnetic load reaches a defined position within a time window. The duration of the time window can be specified so that the current flowing during the time window does not exceed a threshold level. Starting from an initial value, the window duration is increased if the current is below the threshold or reduced if it is greater than the threshold. An Independent claim is also included for an arrangement for driving an electromagnetic load.
