What about the output voltage? The one that you're bidding on is 480v
out. Is it programmable?
The way VFDs work is, they rectify input voltage and then supply
the same voltage as "output", turning it on and off several times per
second. So the output voltage is, more or less, the input voltage.

Iggy dont most three phase motors relink to be a 240 or 480 so you
wouldnt even need to play with it?
What happens if you just feed the 480V VFD 240V?
It would say something like "UV" in the display, and refuse to
do anything.
