introduction：Panasonic servo driverDescription and solution of the fault： 1、Panasonic digital AC servo systemMHMA 2KW，Power on the machine when testing，The motor vibrates and makes a lot of noise，And then the drive appears16Number alarm，How to solve? This phenomenon is usually due to the drivers gain setting too high，It produced a self-excited oscillation。Please adjust the parametersNo.10、No.11、No.12，Appropriately reduce system gain。 2、Panasonic AC servo drive is powered on22Number alarm，why? 22The alarm number is an encoder fault alarm，The causes are generally： A.Theres a problem with the encoder wiring：disconnection、short-circuit、Misconnection and so on，Please check it carefully; B.Theres a problem with the encoder on the motor：malposition、spoilage，Please send for repair。 3、Panasonic servo motors operate at very low speeds，Sometimes fast, sometimes slow，crawling，What should I do?? Servo motor crawling phenomenon is generally due to the system gain is too low caused，Please adjust the parametersNo.10、No.11、No.12，
