1) Check if there is balanced three-phase output between U, V and W.If yes, the motor circuit or
itself may have been damaged, or the motor may have stopped running for mechanical reason.
Please remove it.
2) If there is output but the three phases are not balanced, the inverter drive board or the output
module may have been damaged. Please seek for technical support.
3) If there is no output voltage, the drive board or output module may have been damaged. Please
seek for technical support.
4. Upon power-on, it is displayed that the inverter is normal, but after it starts running, the circuit
breaker of the power supply trips
1) Check if short circuit occurs between the output modules. If yes, seek for technical support.
2) Check if there exists short circuit or earthing between the motor lead wires. If yes, please
remove it.
3) If the tripping occurs only occasionally and the distance between the motor and the inverter is
big, it is acceptable to install output AC reactor for troubleshooting
