Err 1. There is no rotation signal, the motor does not rotate or the position sensor position does not match, the sensor is bad and the plug is loosely contacted, and the computer board is broken.
Err 2. During the computer's collection of test data, the rim speed is less than 60 rpm. If the roller is not installed and the belt is too loose and too tight, it will cause an error.
Err 3. Calculation error, the amount of imbalance exceeds the calculation range.
Err 4. The motor is reversed and the position sensor wiring is incorrect.
Err 5. Self-calibration error or self-calibration data is lost and self-calibration is required again.
Err 6. Self-calibration error, it may be caused by the failure to add 100g balance block or pressure sensor cable disconnection during the second rotation, the pressure sensor is broken, and the plug is loosely contacted.
