Abstract

Bei einem Verfahren zur Steuerung eines elektromagnetischen Stellantriebes ist eine Schaltungseinrichtung vorgesehen, die einen Eingang (80.2) zum Anschluss an eine Versorgungsspannung (UV), einen Eingang (80.3) zum Anschluss an GND, zwei Ausgänge (80.4, 80.5) zum Anschluss eines Stellelements, mindestens ein Schaltelement (10) zur Unterbrechung der Stromversorgung und eine Einrichtung (20) zur Erfassung des Stroms aufweist. Ein Steuerelement (60) dient zur Messung von Strom und Versorgungsspannung sowie zur Steuerung des wenigstens einen Schaltelements (10). Das Stellelement wird von dem wenigstens einen Schaltelement (10,30) unter Pulsweitenmodulation angesteuert. Dadurch, dass das Stellelement zeitlich begrenzt mit einer Leistung übererregt wird, welche über der Nennleistung des Stellantriebs liegt, und dass das Steuerelement (60) anhand von Strom und der Höhe der Versorgungsspannung des Stellelements im übererregten Zustand die Nennleistung anhand einer Vielzahl dem Steuerelement bekannten, verschiedenen induktiven Lasten unterschiedlicher Nennleistung bestimmt, werden Ventilspulen nach ihrer Nennspannung identifiziert und für den industriellen Einsatz nutzbar gemacht.

In a method for controlling an electromagnetic actuator, a circuit device is provided which has an input (80.2) for connection to a supply voltage (UV), an input (80.3) for connection to GND, two outputs (80.4, 80.5) for connecting an actuating element, at least one switching element (10) for interrupting the power supply and means (20) for detecting the current. A control element (60) is used to measure current and supply voltage and to control the at least one switching element (10). The actuator is controlled by the at least one switching element (10,30) under pulse width modulation. Characterized in that the control element is overexcited for a limited time with a power which is above the rated power of the actuator, and that the control (60) based on current and the level of the supply voltage of the actuating element in the over-excited state, the rated power based on a variety of control known, determined inductive loads of different rated power, valve coils are identified according to their rated voltage and made available for industrial use.
