Need help with a Delta VFD

[Tooly236]

Hello all, I bought a 3 phase mill and I only have single phase 240 at my house. I am in mexico, so where I want to buy the VFD nobody can explain anthing to me in english that I can understand. They have a Delta VFD037EL23A which I think is what I need, can anyone explain what it should look like after it is wired because I am not sure that these guys know much, although they know alot more than me. I attatched a picture of the VFD and my Mill Motor. Thanks everyone

I'd start by seatching on the model number and reading the manual


I did that and got this
Delta VFD37EL23A | Delta AC Drives - Delta VFD

It's a three phase input
NFG for you.



Actually
I'd go to KB electronics, they have USA based customer service tech support and engineering.
Distributed in Canada by Motion and others.

I think that means it is capable of taking in 3 phase, because I have found other spec sheets that have the input at 240 single phase.

Delta VFD037EL23A

After the "EL" is the input requirement:

11:115 1-phase
21:230 1-phase
23:230 3-phase
43:460 3-phase

You need a model with "21" in the model number.
The manual says nada about a de-rating connection.

More specifically, the manual specifically says DO NOT connect 3 phase models to a single phase supply (page 31).
There is also no way to defeat the Input Phase Loss detection, so it will not function at all.
