Well, it was popping up with er 7, which on my VFD, is inverter overtemp. So, I did what any somewhat normal person would do and took it apart to maybe put some better thermal compound on the components that were touching the Aluminium heatsink.
Well, when I got it down to almost bare bones without removing the screws for the components touching the heatsink, I see that it says 220v for power in (explains why there is no actual ground on the board and I had to rig another). The wording for the connectors there were actually hidden under the plastic top cover, so I had never noticed it until it was taken apart (See attachment).
So, my question. Should I actually be running this on 110v or should I stop using it until I can get 220v in the shop? I had originally gotten the 120v combo for the simple fact that building code for my state requires you to route a form to get 220v ran to a shop/seperate garage and the city has to come out and run the cable for said endeavor.
P.S. It runs fine when I'm above 200hz, but not when I go down below that. Can I possibly change the parameters to go from 0-200hz range for the max range of the power supplied, which is 120v?
