In the first method, you can analyze the reason according to the status displayed on the inverter, such as whether the fault code is displayed normally, whether there is a running code displayed normally, or whether it is displayed at all (in the case of input power), indicating that it is The rectifier has malfunctioned. If it is in standby mode, it is also possible that the signal source is not set correctly. If the protection function of the inverter is perfect, it will be displayed on the inverter as soon as there is a problem with the motor.
The second method is to see if the inverter has an output frequency, and then use the frequency conversion manual control to see if the motor can rotate. If there is no frequency output, check whether the analog output has or not. If there is no analog output, check whether you have input or not, and whether there is any error in debugging.
The third method is to see whether the inverter is in use or newly installed. If it is being used and the motor does not work, then there is a problem with the motor; if it is newly installed, it may be a problem with the settings.
The fourth method is to remove the output end of the inverter, and then turn it on again to see if the inverter has frequency output. If there is frequency output, the motor is broken. If there is no frequency output, it is the problem of the inverter itself.
