Cause : Automatic Calibration Failure. A calibration error occurred when automatically calibrating the analog inputs / outputs or the current actual value sensing. In the factory, the calibration is only carried out once. This means that fault F0040 is only to be expected during the production process of the drive converter and not while the converter is being used.
Hardware problem.
