Zusammenfassung:Disclosed are a method and an arrangement for triggering a piezoelectric actuator, which allow a piezoelectric actuator to be triggered by means of a negative voltage if the actuator leaves the defined initial position thereof due to external influences. The inventive arrangement comprises a polarity reversing device (S1) for triggering the actuator (P) by means of a half sine wave.
