Not sure if this is "electrical," but...
I have a Hitachi SJ200 VFD on my belt grinder. Today I noticed the potentiometer knob had come off the control panel, which detaches from the VFD and is remotely mounted using a CAT5 cable. I tried to control the grinder using just the shaft, but the shaft was messed up. I was about to order a new remote when I decided to pry the control panel apart to see what was wrong. I found I could repair the potentiometer, which was somewhat amazing given the low quality of the part. Now all I have to do is find the knob, which is surely on the workshop floor somewhere.
Having dodged a $75 bullet (cost of a new panel), I now want to put the panel in some kind of enclosure to protect it from getting bonked again. I also want to keep dust out of the pot.
I'm wondering if anyone else here has tried this with a Hitachi SJ200 or similar VFD. Hitachi sells a "NEMA 4X kit," which appears to be a plastic frame that goes around the panel. It's ridiculously expensive. I'm thinking maybe I should make something for myself.
