Why would you use that when it's clearly a completely different control box to what you have.? Just because it's called 3040 doesn't mean they are all the same.!
You need the relevant docs to the control box you have. In any case that type of document wouldn't be any use for checking the VFD parameters or setting it up.

I can't help if you haven't got the Docs because it's not something that can be guessed at.!
