Hi guys, hope you are doing well. Well, today I tested it again and had the same behaviour as before. It works perfectly at the beginning but then it fails and gives me an overcurrent alarm.
I took it apart and nothing seems to be wrong at first sight. I'm thinking about replacing the capacitors module but for that I'll have to wait a couple of weeks for the new module to arrive. I can desolder and install new capacitors on this module, but I can't find something as big as these ones here in Argentina. So I think I'll get a new VFD and with that solved I'll repair this one. The best VFD I can get here in terms of cost benefit is a YASKAWA GA500 that reaches up to 590 Hz. It's more than ok for me since I don't usually go more than 500 Hz with this one so that's my solution at this point.
