1. A drive unit for driving a voltage-driven element, the drive unit comprising:

  • a switching circuit; and

    an abnormal signal generating circuit, whereinthe switching circuit is configured to be connected to an external time generating circuit, and is configured to switch a driving condition relating to a driving voltage of the voltage-driven element during a transitional period between a driving state and a non-driving state of the voltage-driven element based on a measurement time which is measured by using the time generating circuit, andthe abnormal signal generating circuit is configured to generate an abnormal signal when an accurate measurement of the time using the time generating circuit is not executed.
