VFD Digital Phase Convertor 2.2kW 3HP 220V Single to 3 Phase | Variable Frequency Drive.Vector Control,220VAC Input/Output,0-400HZ Output,10A,for ≤3HP CNC Motor Speed Control

Documentation is better than most. Responsive support helped resolve confusion during non standard setup. One year on, still working well in a ~50% duty cycle application (I used it to replace the massively overpriced, totally unreliable VFD in my geothermal HVAC system)

Used on a 2HP Metal Lathe and seems to be working well. Had a few programming questions and posted them through Amazon and received timely answers directly from Huanyang product support. There is a slight electrical noise (whining) that comes with using a VFD but it is definitely worth the flexibility of speed control and breaking that you don't get with a phase converter... not to mention the cost difference. The "auto-tuning" feature takes a lot of the guess work out figuring out the motor parameters.

Product is misrepresented. It will not work with the horsepower motor as advertised. I found out too late to return it, my electrician read the brochure and it tells you to buy the next larger size. Not I'm out the money with a useless item. False advertising.

I bought this to run a 2HP motor on a Bridgeport copy that is 3 phase. Like others say, the manual has some errors. It shows on the wiring page to hook up the single phase power to R and T. It didn't work that way. Hook it up to R and S. The best advice I can give is that before you order it spend some time on YouTube to see where others have struggled or succeeded . Do a search for "Huanyang GT" There you will find several videos including "VFD GT series operation" I took my laptop to the shop and followed it step by step. It ran perfectly with no issues at all and I have never wired a VFD. Watching videos will get you familiar with the functions. Great bargain for the money if you have some electrical skills! You will need to wire in a disconnect and likely low voltage control wiring. I went through the extra effort to install it in a enclosure. EDIT: After a successful install, I bought another larger unit for my 5hp Lathe. More challenging to install but well worth the effort. The amount of electrical hardware you get to remove is staggering! My personal opinion is to stay away from "Autotune" and just enter your basic motor parameters and HZ. Start slowly. As you learn the programming language things will start to click and make sense. Managed to get everything programmed exactly how I wanted it including the mechanical brake. Great product for the money. Patience.....required for this project but I couldn't be happier with the results!

Bought this to drive a 400Hz 2.2kW spindle motor for my CNC router. Auto detect of motor parameters ran without error, but took forever and apparently didn't result in the right values. The motor just buzzes and twitches once when attempting to run in vector mode. Did some digging online and found that this combination is hard to get to work and I may need to do tricks like running the calibration with scaled motor ratings. After some fiddling, I decided it was easier to just use this in V/F mode, effectively making it the same as the non GT version of the inverter. Works fine in this mode, but was really hoping to get vector mode working.

I bought the 2.2 kW drive. I feel it was a good value. It allowed me to install 3-phase mill in my single-phase shop. I easily programmed a steady-state 60 hertz and quick ramp times. I did e-mail the company with an initial question about the power-in connections. The wiring diagram was incorrect. My e-mail must have been lost in the ether, because I never did get an answer from the company. A quick You Tube search answered my question and I moved ahead.. Additional enclosures may be required, depending on the installation environment.

I installed this VFD on my bBridgeport Series 1 knee mill (1HP). I have only tested this out briefly as of yet, I did let it run overnight at a slow speed and it was working in the morning. Setting up the parameters was not very difficult, the seller has good youtube videos to show you how and it seems to work as it should. Now i did have one minor issue with the keypad button decal peeling off, I contacted mfg/seller regarding this, they were very responsive and rectified the problem quickly. I cannot comment on the longevity or reliability yet, since I haven't actually made chips with it yet. But if you are a hobbiest like me and need an affordable VFD I would not hesitate buying one again. UPDATE: May 2021. Still working good. Still happy with it. However, I am using the display remotely with the longer ribbon cable. Led digits flicker randomly in cold weather. ~ Under 50F.

This VFD seems to be one of the popular low cost VFDs available. I put it in a cabinet away from the dust as the unit is open to whatever is in the environment. There are YouTube videos that provide information on how to program the VFD. The manual has programming information but was written by someone whose English is not their first language. My unit runs a 2HP Dayton on a belt grinder.

je l'utilise pour ma perceuse a colonne en mode vectoriel. Ça fonction a merveille le manuel de l’utilisateur est bien fait mais seulement en anglais.
