The ACS800 inverter displays error 2310

This post was last edited by Yu Qin on 2021-1-27 22:05. The ACS800-01-0075-3 inverter stopped working suddenly while production was running smoothly. No abnormalities were found in terms of process or machinery; the current during normal operation is only 30A, which is relatively low. Under normal operation, the variable frequency speed is 80% and remains unchanged. It occasionally shuts down due to failures during operation (this has happened twice this year), and there are no alarms from the DCS regarding current levels or anything similar.
Hey, fellow sea traveler, let me complain a bit! The ABB ACS800 frequency converter trips due to an overcurrent fault. There are various reasons for this overcurrent, but based on the symptoms you described, it is generally caused by a sudden change in the load! Alternatively, you can check whether the power of the inverter selected for use on site matches the power of the motor; generally, it is necessary to choose an inverter with a power level that is at least 1.2 times the motor’s output power to ensure reliable operation At the same time, it is necessary to confirm how long the power cable of the variable-frequency drive motor is, and whether the inverter is equipped with an output reactor If there is no output reactor, it needs to be added! Appendix: Preliminary investigation and handling of the 2310 fault alarm message: 2310 (OVERCURRENT) 3.05 FW 1 bit 1 – Excessive output current. Exceeded the trip limit value. 1. Check the motor load. 2. Check the acceleration time. 3. Check the motor and motor cables (including phase sequence). 4. Check that the motor cable does not contain power factor correction capacitors or surge absorption devices. 6. Check the encoder cable (including phase sequence). 2310: OVERCURR xx – Overcurrent fault in the inverter modules connected in parallel at 3.05 FW 1 bit 1 and 4.01. xx (1…12) is the number of the inverter module. 1. Check the motor load. 2. Check the acceleration time. 3. Check the motor and motor cables (including phase sequence). 4. Check the encoder cable (including phase sequence). 5. Check the motor rating in parameter group 99 START-UP DATA to confirm that the motor module is correct. 6. Check that the motor cable does not contain power factor correction capacitors or surge absorption devices.

The power of both the motor and the inverter is relatively **excessive, and it is normal for them to operate properly for many years. There was an overcurrent trip that occurred recently. I’m not sure if it’s caused by inadequate maintenance of the ACS800
Check the fault current value during overcurrent tripping before making a decision
No alarm was triggered; during normal operation the current was around 30A, and it remained at 30A until the trip occurred. The interlock setting was 90A, but nothing else happened – it just tripped.
Dear sea friend, I suggest that you first check the current curve through DCS to see if there are any records available! If so, it will be quite troublesome if the DCS system isn’t configured; generally speaking, an electrical SCADA system cannot capture instantaneous current fluctuations on its own! Based on the situation you described, if process loads at the site or equipment issues can be ruled out, then you can look for the cause within the inverter itself. Modify the acceleration time (increase it by about 5 seconds), and check whether there is a significant difference between the power factor value during motor operation and the motor’s rated value; if such a difference exists, it is necessary to adjust the motor parameters! Additionally, if the problem still remains unresolved, you can try replacing the inverter, as there is a high possibility that there is an issue with the current detection circuit inside the inverter (such as transformers or Hall elements); generally, regular maintenance technicians won’t be able to fix this! I hope this helps!
Thank you. The current configuration is set, there are records, and everything is normal. Additionally, during normal operation, the frequency conversion of the inverter is fixed and not adjusted. We also suspect there is a problem with the inverter itself. Thank you very much.
I think there’s a problem with the inverter itself
Replace the control relay, and ground the outgoing and incoming cables. I have encountered this type of fault many times here, and it’s not easy to resolve. Another thing to check is whether there is any problem with the incoming circuit breaker. What I tried were these few methods based on that approach; it’s hard to say whether they can solve the problem.
