What are the main faults of frequency converter?

Over-voltage, under-voltage, over-current, overload, no display at power-on, over-temperature, no pull-in at power-on and lack of phase.

Energy-saving principle of frequency converter speed regulation operation The equipment that realizes frequency conversion speed regulation is called frequency converter.
