Customer Reviews for VEVOR VFD 4KW, Variable Frequency Drive 18.5A, CNC VFD Motor Drive Inverter Converter 220V, for Spindle Motor Speed Control (1or 3 Phase Input, 3 Phase Output)

Works well, but you must control the acceleration and deceleration, using the parameters. I use this to control my 3 phase motor from my 220 volt ac power .

Wish the instructions weren't in Chinese grammar. Difficult to follow. Best if you have some background in electronics. If not, find an expert.

This is my go-to VFD for small size and big performance. Easily runs 3HP Cabinet Table Saws, and is easy to hide on the saw.

Has been doing great once I got the wiring figured out.

Updating a negative review. It actually works correctly. For the most part. There are parameters that will throw a code when not set correctly. Basically if you demand too much of an extreme, either starting with too low a speed, or shutting down too fast, you'll get a code. So it took me a bit of playing around, but it works as it should.

Documentation/manual is well written and clear to understand. Make sure you set the VFD to match the motor frequency, it's set for 400hz out of the box and likely will need to be changed to 60hz or you won't get any power out of your motor but it will still spin.

Well packaged, been functioning like it was supposed to. Pleased with this VFD so far.

It didn't last a month, but I did video troubleshooting, and they quickly resolve my problem, and I was back up and running in a couple of weeks.

Just what we wanted
