You can first disconnect the load and then restart the machine. If it still fails to start, the boost part of the inverter is broken. Our suggestions are as follows: check whether the IGBT is broken down; 1. If there is no breakdown and there is 380V DC voltage, the control board is out of order. Then you can replace the IGBT. 2. If the IGBT is broken down, it is not easy to maintain.
