INVERTER CONTROL METHOD

Two current threshold values are adopted, which are larger than the upper limit of current of an operating region. When a rotating speed is smaller than a speed threshold value, the current threshold value is adopted as a criterion to judge whether an input current to an inverter is abnormal, and wh...

Summary:Two current threshold values are adopted, which are larger than the upper limit of current of an operating region. When a rotating speed is smaller than a speed threshold value, the current threshold value is adopted as a criterion to judge whether an input current to an inverter is abnormal, and when the rotating speed Rot is larger than that, the other current threshold value is adopted as the criterion.
