Abstract
A system for driving an electric actuator unit with a polarity-dependent actuation direction contains a driving unit with a voltage input, at least one polarity control input and two voltage outputs whose polarity depends on the polarity control signal at the polarity control input, and a control input. The actuator unit is operated in at least one of the drive directions only if a corresponding polarity control signal is present and the control input is additionally supplied with a predefined control signal.
Claims8
A device for driving an actuator unit via a drive unit, said drive unit comprises a voltage supply input, at least one polarity control input, at least two voltage outputs, wherein the polarity of a signal at the voltage outputs depends on the at least one polarity control input with a signal, and a control input;
- and said actuator unit comprises a drive motor and at least two voltage inputs which are operatively coupled to said at least two voltage outputs, wherein the drive direction of the drive motor is determined by the polarity of the signal at the at least two voltage inputs and the drive motor is operated in at least one of the drive directions only when the control input is supplied with a predefined control signal.
