Sux.. Will not power ON.ssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss

Exactly as described, I see no reason to buy a used VFD when you can get a brand-new one for less. I wouldn't call a VFD "easy to use", it's a technical tool. The manual gives you all the details you need. Still, if you have never set up a 3-phase motor, you're going to need to do some research. If money was not an object, I'd still buy this VFD. (thinking of buying another)

The instructions are a bit vague but seller responded quickly to questions and drive worked flawlessly

I like it so much, this is a very good product, the only bad thing is to delay at delivery

I bought this to run my iron worker because I didn’t have 3 phase electric. My shops single phase . The directions are decent. I wish someone would make a video on how to adjust the settings that’s the only confusing part . I need 60HZ but my machine is working on the factory 50hz setting so for now that’s where it’s gonna stay. I had to bypass the factory control board & wire it directly to the motor. Works great so far . A YouTube video on this would be a lot of help but I couldn’t find one for my application. I am happy with it :)

onbky draw back are the instructions. very complicated to program

Used this as a speed control for a hopper. Works well so far. The instruction manual is a little vague. Maybe geared more towards people who install these for a living yet got it wired in and installed and once got the parameters setup it works very well. Hopefully it will last me a while.

Exactly what I needed and worked perfectly for the electronic lab set up I am doing.

I was looking for a vfd and found this site with great prices and more items to explore. The vfd met all of the specs I needed to power my milling machine. I have bookmarked this site for other items I need for the shop and found many other items that I will need. Shipping was fast to California and I will be back.

Excelente, funciona a la perfeccion, valio cada centavo
