VFD Variable Frequency Drive,Single‑Phase 110VAC Input 3‑Phase 220VAC Output Variable Frequency Inverter,Motor Speed Controller,220V 1500W AT5‑1500X, default

So far, this VFD is working perfectly with a VEVOR 2-HP 230V three-phase motor (also from Amazon) on my lathe. I have just three minor complaints: - The operating instructions that came with it are for models AT1 to AT4, which are all for 220V or 380V inputs. I received an AT5 (as ordered), which is for 110V single-phase input. So, none of the line connection diagrams in the instructions were correct for the AT5. I'm an electrical engineer, so it was easy for me to figure out the right input connections (actually, they are marked on the terminal block), but I wonder if some of the reviews saying it failed or tripped a breaker on connection could be due to connecting it to 220V single-phase input per the diagrams in the instructions? - It is working fine using the default parameters, but being an engineer, I wondered if I could fine tune it a bit by tweaking them. For example, change the startup time, which seems to be almost instantaneous by default. Alas, although the instructions provide an extensive list of parameters, they do not explain what any of them mean! A few are obvious, but others are not. Searching the web, I could find no explanation for these parameters. For example, what is 1st rising velocity? I don't want to fiddle with them unless I know what they are about, so I'm leaving them alone for now. - When you hit the stop button the motor does stop, but the unit remains live, even if you disconnect it from the mains. If you then press the run button, the motor will spin for a few seconds until it discharges the VFD. If you aren't aware of this behavior, you could be injured by the unexpected motor start or could be shocked by discharge of the still-charged DC section of the VFD. Edit: After some more searching, I managed to find explanations for most of the other parameter settings. I just wasn't creative enough in phrasing my queries the first time.

Very nice VFD, I used it for a 1.5hp 220v motor and it’s a perfect match. I didn’t have to change any parameters, plug and play. I see other reviews stating that it doesn’t work with a gfci outlet, but I had it hooked directly to a gfci and there were no issues. Highly recommended.

Typical cheap overseas junk, I ordered in September 4th 2025. I did not get around to installing until the Thanksgiving Holiday. It ran the 1-1/2hp drill press great for about 5-7 minutes and then there was a pop sound and a puff of smoke out the top. Obviously some cheap component inside was defective. Out of date for Amazon return (lessoned learned) no warrenty information in the owners manual. If you go to sellers website it just sends you back to Amazon. I'm out 120 bucks!

It does work.

I used this VFD along with a 1 1/2 HP 3 phase motor to power an older wood lathe. Everything went as it should, and this gave the lathe much more flexibility with the slower, adjustable RPM. I was very pleased on how this worked and would recommend this unit to anyone with this type of application.

What as indicated. Great value

Good value for the money. Pretty easy to install, although the instructions are bit lacking. If I had not had previous experience working with VFD's, it might have been more difficult to wire and program. Some more details on the wiring diagram and on the programming would be more helpful when integrating it different applications.

Worked great on my drill press rebuild with a 1HP motor. Seems to be well made enough as long as it's not abused.

manual could be better, but overall quality is good and the unit works as it should!!

Nunca encontré una guia para conectar dicho variador por más que lo busque.tampoco.me enviaron un instructivo correcto propio del variador estoy molesto al respecto.

Very poorly written instructions. They need to hire some decent translators. Once you work a bit of trial and error you will find the unit works well!

bought dec. 2023. quit working oct. 2025. just over the 18 mo. warranty period. board is burn't, not good. Plus the price now is now 150 % more. rip off

Worked fine
