Some rudimentary electrical/electronics knowledge is a help.
For tuning the VFD, it helps if you get one with the self tuning option.
I have not done one on a bridgeport, the ones I have are Excello, but the principle is the same.

There isn't any need to run a bigger VFD than what the motor rating is, is there? (like to be able to handle the starting load of the motor)
