Method for testing a capacitive actuator

摘要

A capacitive actuating element is driven using a control signal of duration T1. This duration T1 is related to prescribed or measured values for charging, discharging and open periods T2, T3 and T4: (T1+T3-T2-T4)<=|X| and is compared with a magnitude (limit value |X|). If a magnitude greater than |X| is obtained, then a fault is inferred.
