Hello, I face almost the same problem with exception that my Micromaster440 GF 6SE6440-2UD38-8FA1 driving a compressor (PID regulated; sensorless vector mode) was damaged by lightning storm followed by F0022. When I replaced the power stack (A5E00825001 PCB together with IGBTs) and started the compressor, very fast changes of frequency could be seen on BOP followed immediately by F0004. Than I parameterised the VFD to be controlled by AOP, set V/F control, connected a 7.5 kW motor and started again. The motor ran OK. Vdc was about 560V, motor current, voltage and inverter temperatures were OK. It is importened that all the time a red LED was lit on the rectifier PCB A5E00412608. What does it mean? I could not find out anything about that LED. Please help me. Thank you!
