Method for actuating piezoelectric drive unit

The invention relates to a method for actuating the piezoelectric drive unit (81). In this case, a first actuation signal is applied to a first electrode (90a) of a first piezoelectric element (95) of the piezoelectric drive unit (81). In addition, a second actuation signal is applied to a second electrode (90b) of a first piezoelectric element (95) of the piezoelectric drive unit (81). The first control signal is configured in the form of a continuously positive first voltage signal. The second control signal is a constant second voltage signal. The first control signal is always larger than the second control signal. 本发明涉及一种操控所述压电驱动单元(81)的方法。在此，第一操控信号被施加到所述压电驱动单元(81)的第一压电元件(95)的第一电极(90a)上。附加地，第二操控信号被施加到所述压电驱动单元(81)的第一压电元件(95)的第二电极(90b)上。第一操控信号构造为连续正的第一电压信号的形式。第二操控信号为恒定的第二电压信号。第一操控信号始终大于第二操控信号。
