Hello Friends,
We are having problem with ABB ACS 880-04-650A-3 VFD , showing short circuit fault 2340. Even after isolating the power cables the fault was still persisting. So we opened the VFD drive for fault trouble shooting and we found that the Gate driver board BGDR-01C had a flash on its card and we did not found any other problem. So, we replaced the Gate driver board and started, again the same problem is coming and again gate driver board failed. Kindly suggest how to trouble shoot this problem and what are the possible causes of the problem.
Thank you
Regards
