Greg,
How many HP is the motor?
I'm not sure what would happen if you were to power up the VFD with the switch in the Off position. I doubt anything would happen but it would be best to contact tech support of the manufacturer.
The VFDs that I've worked with have parameters for at least two different motors so you should be able to program it to handle both sets of windings.
The self-check takes about 5 to 10 seconds for the VFDs I've worked with. Not even enough time to pick your nose or scratch your balls.
You shouldn't have any problem using the existing switches. That's what I'm going to do once I get around to VFDing my lathe. I have all of the pieces, just no time.
On the fly speed control is nice. All it takes is the cost of a potentiometer so it's well worth doing.
Hope this helps some.
Ed
