Abstract (en)

The device (1) has a drive (3) e.g. brushless electric motor or collector-less electric motor, for driving an actuator (5), and an adjusting circuit (2) e.g. hydraulic valve or pneumatic valve, for adjusting a three-point signal to predetermined parameters. The parameters are voltage type, voltage value, current value or frequency of three points. A circuit arrangement (8) of the device is designed in such a manner that an input (11) of the device is loaded with direct current or with alternating current three point control signal. The circuit has a constant current control unit (17).
