Vfd wtf

How do I set up this vfd to run my Edward’s 30?

It used to be set up already and now it seems I need to reprogram it.

Help I’m electrically challenged

What type of VFD? I would like to do some splorin



What function are you trying to program?


I just want to run my pump no clue what I’m staring at. Sorry I’ll start reading that manual

Nevermind, that error code is the low voltage trip error code. You can find more information on page 49. I hope you see this before you start reading!!!


Ok, I had this guy wire it up and he swears 115 v plug is ok even though last time it ran on a 230.

That sounds wrong. The manual specifies at least 208

Now I’m really curious :popcorn:

Probably have to take a look at that manual.

Your electrician would seem on solid ground based on my reading. I plan on using a VFD tomorrow morning to turn 110 single phase into 220 three phase. My manual suggests it should work with my controller :slight_smile:

a low voltage error on the other hand suggests your controller would at least like someone to explain what it is being fed.

I really should read the manual before guessing further


Page 12 states voltage inputs and outputs
