METHOD FOR THE DIAGNOSIS OF A DROP IN LOAD

摘要

A method for diagnosing a load drop in a piezo actuator in an injection device, a voltage being measured and being compared to a threshold voltage (24) for the diagnosis, the load drop being present if the measured voltage is greater than the threshold voltage (24). The present invention also relates to a device for diagnosing a load drop in a piezo actuator in an injection device, to a computer program and to a computer program product.
