Chapter 7 Troubleshooting
HD30 series inverter has inbuilt protective and warning self-diagnostic functions. If a fault occurs,
the fault code will be displayed on the display panel. At the same time, fault relay acts,
accordingly the inverter stops output and the motor coasts to stop.
When fault or alarm occurs, please record the fault details and take proper actions according to
the below Table 7-1. If you need some technical help, please contact to the suppliers or directly
call Shenzhen Hpmont Technology Co., Ltd.
After the fault is eliminated, please reset the inverter by any of the following methods:
1. Display panel.
2. External reset terminal (multi-function terminal set as No. 46 function).
3. Communication.
4. Switching on the inverter after switching off.
