Abstract (en)
[origin: DE19723931A1] The invention relates to a device for controlling an electromechanical setting device, comprising a final setting element and a setting drive mechanism. Said setting drive mechanism comprises an electromagnet which has a core (112) and a coil (113). The setting drive also has a moveable anchor plate (115). A controller is provided, the control variable of said controller being the current through the coil (113) and the setting variable being a voltage which is applied to said coil. A source of voltage (8) is also provided to produce the supply current. A pulse duration modulator (42) modulates the setting variable in dependence on the supply voltage.
