  • Publication number: 20190353276
    Abstract: The piezoelectric actuator includes a piezoelectric element; a power supply applying a voltage to the piezoelectric element; a drive circuit that applies a voltage from the power supply to the piezoelectric element by a pulse charge signal and a discharge signal to charge, and discharges the charge charged in the piezoelectric element to drive the piezoelectric element; an abnormality detection circuit that detects an abnormality due to insulation failure of the piezoelectric element, and a control unit that determines whether or not the piezoelectric element is normal based on an abnormality detection signal. The abnormality detection circuit outputs the abnormality detection signal that detects a time corresponding to a period from when a current starts to flow to the piezoelectric element during charging to when a current stops to flow, and it is determined that the piezoelectric element is abnormal when the time is equal to or more than a set time.
