ABB inverter fault codes
https://seasons4.net/wp-content/uploads/2012/11/ABB-Fault-codes.pdf
here are some of the common ABB inverter fault codes:
- E01: Overcurrent. This means that the inverter has detected an overcurrent condition. This can be caused by a short circuit, an overload, or a faulty component.
- E02: Undervoltage. This means that the inverter has detected an undervoltage condition. This can be caused by a low mains voltage, a faulty component, or a loose connection.
- E03: Overvoltage. This means that the inverter has detected an overvoltage condition. This can be caused by a high mains voltage, a faulty component, or a loose connection.
- E04: Overtemperature. This means that the inverter has detected an overtemperature condition. This can be caused by a high ambient temperature, a faulty component, or a blocked heatsink.
- E05: Overcurrent on DC link. This means that the inverter has detected an overcurrent condition on the DC link. This can be caused by a short circuit, a overload, or a faulty component.
- E06: DC link undervoltage. This means that the inverter has detected an undervoltage condition on the DC link. This can be caused by a low battery voltage, a faulty component, or a loose connection.
- E07: DC link overvoltage. This means that the inverter has detected an overvoltage condition on the DC link. This can be caused by a high battery voltage, a faulty component, or a loose connection.
- E08: Inverter temperature. This means that the inverter has detected an overtemperature condition on the inverter’s internal components. This can be caused by a high ambient temperature, a faulty component, or a blocked heatsink.
- E09: Communication error. This means that the inverter has lost communication with one of its components. This can be caused by a loose connection, a faulty component, or a software issue.
- E10: Fault on IGBT. This means that the inverter has detected a fault on one of its IGBTs. This can be caused by a short circuit, a faulty component, or a mechanical failure.
These are just some of the most common ABB inverter fault codes. The specific fault codes that your inverter displays may vary depending on the model.
If you see a fault code on your ABB inverter, it is important to first check the user manual for the specific meaning of the code. The manual will also provide troubleshooting tips that you can try.
If you are unable to fix the problem yourself, you should contact a qualified technician for assistance.
Here are some additional tips for troubleshooting ABB inverter fault codes:
- Reset the inverter by turning it off and then on again.
- Check the connections to the inverter. Make sure that all of the connections are tight and secure.
- Check the inverter’s cooling system. Make sure that the heatsinks are clean and free of dust.
- Check the inverter’s fuses. Make sure that the fuses are not blown.
- Contact a qualified technician for assistance.
