I have one Allen Bradley 5 hp, the other fives and the tens are Woods. The smaller inverters are Danfoss and Baldor. I think I also have some yaskawa and mitsubishi small inverters.

I have years of experience with these brands and they are very good. The Woods have held up under some very adverse conditions and simply run for years and years. I've never had to replace a Danfoss or a 'baby' baldor.

I have the necessary manuals for most of the inverters, and tech data is readily available on line.

If ya really wanna get crazy, I have some PLCs, clutch packs, a few prox switches, DC power supplies... lotsa industrual electronic goodies.
