Hey All,
I have a 1992 Fadal VMC40 with the mitsubishi Freqrol Z300 Model Z320-7.5k-UL. I often get a spindle fault upon starting the machine, but when I let it warm up and sit for half an hour or so it works no problem. I figured it was the inverted because I was getting an alarm on it and would have to reset.
Today, the inverter just started smoking.
I assume I'll have to replace it, but I'd like to take a look and see if there's something obvious that I or someone substantially more qualified could repair.
My question is this: What are the dangers of working on inverters that have previously been under power? I'll identify the capacitors and discharge them. Is that the only risk? Anyone have experience with these inverters in particular? Or have an idea of what might be going wrong?
Thanks as always.
