Q : When will the error code E0084 be generated?

A : E0084 is generated whenever the measured current for the main motor is below 20% of the nominal rated current (P14.03) for over 10 seconds. We do not generate this error if VSD is used. So we only do this when fixed speed is selected. The idea behind that is whilst running the current should always be in the close range of the rated current for a fixed speed motor. If you measure below 20%, there must be something wrong with the sensor.
