I don't leave a ton of reviews, but this VFD work so great for the price i had to let it be known. I installed this product on my 3HP lathe and it worked flawlessly. The VFD ran very quietly and my motor had perfectly balanced current unlike the digital phase converter i purchased previously. One thing thing i can say is be sure to set P011 to 02 if you use any of the remote terminals. It states this on the amazon page but the instructions do not.

I'm using this for a belt grinder.I thought it had fried one day. Saw a big spark at the control box and blew the breaker in my panel. But, it was my own fault. Either the wall switch or the control box got some grinding dust in it and that's what caused the problem. I reset the breaker and all was well. I then got a bit wiser and put a ziplock over the top of the switch and the panel to keep grinding dust away from them. It's been working flawlessly for 4 or 5 months now.Point is, the VFD is great. I'm running a 1.5HP 220v Hallmark 1800 RPM motor. I over-speed the motor by 50% (90 on the frequency dial) to get 2700 RPM. Supposedly, I should be able to turn it up to 120 or even 130...but I'm pretty happy where it's set now.FYI, I don't think I had to change any settings to initially run with a frequency cap of 60. So, very easy to set up.The wiring space is a bit limited. MY tip is: Don't use wirenuts - use WAGO connectors. They fit much more easily.

Got it working. Works so far. Would be cool to see videos on programming for even easier ease. Also, does anyone know what kind of remote controls work for this? It's probably just buttons into the external terminal and I just haven't learned it yet. Anyway, great product for the price.

I have bought 2 of these now. First went on a lathe upgrade for my nephew, and the next one replaced a broken VFD on my wife's lathe. Wiring was super simple and this is even nicer than one that came on another lathe we have. Very nice to be able to stop the motor and when you hit run it goes back to the set speed.

THE GOOD:- It worked when powered up!- The parameters were preset pretty decently for my drill press.- It is a simple VFD with few settings to worry about but still has the basic features needed.- Far less expensive than big name VFDs.THE BAD:- It is not safe for facemounting without a box/enclosure. This was a big deal for me. I was working with 10 AWG SOOW and my older unit (a Delta) was set up to accomodate with appropriate cable clamps meeting code so the individual conductors were enclosed at all points where the outer jacket was stripped. In order to safely fixt this problem, I had to mount the VFD inside of a UL listed electrical enclosure.- The wire terminals were too small for the appropriately sized conductors. Could I get #10 wire in place? Yes, but it was a job. The terminals have a wire clamp similar to what might be found on a NEMA plug, but it was VERY difficult to get the wire into the clamp without a terminal end. As others noted, the terminals are not big enough to accomdate a forkl terminal much less a ring. I ended up stripping the jacket and soldering the tightlest twisted conductors so no loose strands would create an opportunity for arc or short.THE UGLY:- I remain apprehensive given the comments others have made about the unit failing soon after installation. Only time will tell but it would be nice to have a little confidence in the product.

I used the AT1-1500 2HP unit to power up a 1966 Bridgeport Series 1 1 HP mill. The motor was originally wired for 440 VAC 3-phase. I only had 220VAC 1-phase in my barn. I reconnected the motor leads for 220VAC. The unit worked flawlessly in converting 1-phase to 3-phase. I am an engineer and have installed many VFD drives. The instructions are somewhat difficult to understand. There several videos online that are helpful and the seller's tech team responded to emails within 1-2 days. There are a few things that the unit does not like. Most Bridgeports have a reversing drum switch mounted on the motor. My original intent was to power up the VFD with the run command at the same time. The VFD goes through a brief self diagnostic routine when it is first powered up. Calling for a run command at startup caused an Error 1 display. When I added a separate Off-Run switch, the unit functioned without error since there was an inherent delay between powering the VFD and switching it into run mode. Secondly, the unit did not work with the reversing drum switch. After switching the VFD to run, I actuated the drum switch and the unit tripped out on overload (Error 2). Positioning the drum switch in forward or reverse before commanding the VFD into run eliminated this. I removed the drum switch and replaced it with an aluminum junction box from Amazon. I changed the Off-Run switch to a 3-position Reverse-Off-Forward switch and wired it to terminals X4 and X5. The motor worked perfectly. I set the minimum Hertz (P07) to 60.0. Running an older, non-inverter duty motor at less than full RPM can cause it to overheat. A replacement motor is $1500. I am content to change the belt drive step pulleys. Lastly, because the AC sine wave current is generated by modulating pulses of DC current, a standard Amprobe meter will not read the correct input or output amperage. But, the motor amp draw can be displayed on the control unit.

I bought this for a 2hp motor. It worked fine for the first day, after that it randomly trips on error 1. I've tried to reach the seller or some type of customer service. All I've received from customer service was an automated message stating they are not available right now. I bought a larger one thinking that I made a miscalculation in sizing, same issue. Replaced both with a different brand VFD and I've had zero issues.

Me funcionó tan bien que compre 2 piezas. Lo ocupe para alimentar a una fresadora ya qué sólo cuento con luz a 120 volts. Alimento a 120 volts y me da de salida trifasica 220. Muy fácil de programar se los recomiendo ampliamente. Excelente precio calidad

Error 1, incluso sin motor conectado.
