Problems solved by technology

However, in the existing inspection and display methods, one is to display the first detected inverter fault through the digital tube, and after the inverter fault has been detected, other fault protection modules will not be executed, that is, only the fault protection module is detected at the same time. Output and display an inverter fault; the other is to continue to execute other fault protection modules after the inverter fault has been detected. If there are other inverter faults, it will display the latest detected inverter fault, which will overwrite the current latest displayed inverter fault. other faults displayed before the
It can be seen that the existing technology can only detect a certain fault of the frequency converter, and cannot display multiple faults of the frequency converter at the same time
