METHOD FOR CONTROLLING A PIEZOELECTRIC DRIVE UNIT

The invention relates to a method for controlling a piezoelectric drive unit (81). For this purpose, a first control signal is applied to a first electrode (90a) of the first piezo element (95) of the piezoelectric drive unit (81). Additionally, a second control signal is applied to a second electro...

Zusammenfassung:	The invention relates to a method for controlling a piezoelectric drive unit (81). For this purpose, a first control signal is applied to a first electrode (90a) of the first piezo element (95) of the piezoelectric drive unit (81). Additionally, a second control signal is applied to a second electrode (90b) of the first piezo element (95) of the piezoelectric drive unit (81). The first control signal is configured as a continuous positive first voltage signal. The second control signal is configured as a constant second voltage signal. The first control signal is always greater than the second control signal.
