ATV310 Modbus Fault Address

[ogidi]

Good day, everyone.

I am working with a Schneider ATV310 drive, communicating via Modbus RS485.
I need help finding the Modbus register address where fault information is stored.

Specifically:

• What is the exact Modbus register address for reading faults?

• Is it a word (16 bits)?

• If yes, what does each individual bit represent?

• Also, what is the command to reset faults via Modbus?

I have already gone through the ATV310 Modbus Address List Excel Sheet, but I did not find any register clearly showing the active faults (TOP faults) or a complete list of the fault codes linked to a specific register.

The faults I need to monitor are:

Overcurrent error (F010),
Motor short circuit fault (F018),
Short circuit to ground (F019),
IGBT short circuit (F020),
Overspeed error (F025),
AI input signal loss error (F033),
Output phase loss (F014),
Output phase loss (F015),
Input phase loss (F017),
Communication error (F022),
Schneider inverter low voltage error (F030),
Overheating IGBT (F027),
Overload handling (F012).

Any clear information about the address, the bit assignments (if applicable), and how to send a Modbus command to reset faults will be highly appreciated.

Thank you very much!

Hi you have to check this parameter

It is an enumeration and show you the actual or last fault code as enumeration.

The best will be to combine this value with the alarm bit of the Status word.

Thanks for the reply, how can I do that, as I am new to these things.
