The reason is burning AINT card in Acs800 Multidrive
I checked fiber optic, replace NPBU,
I have PPCC LINK1-OVERCURR2-3 sometime. But the drive is off.
So far, about six have been burnt

Hi,
I'm not sure if I fully understand your question. The better advise is to contact your ABB service organization for competent advise.
From the limited information provided, and fault codes description from the FW manual, I could suggest the following:
- check param 3.19 for fault messages from AINT board. If you have an OVERCURR fault message in idle status, it could be current sensor fault in the inverter?
- check param 3.06 for other type of faults. It could be fiber optic connection to the inverter module 1 fault. Check for wrong connection of FO cables - they could be crossed
- what 6 boards have been burnt?
