Method and device for driving an electric actuator unit |
摘要 |
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.
