Seems to be a quality controller so far - worked correctly without adjustments from first use. I will be using it to control a 2hp 3phase motor at 240v on a belt grinder. Changing setting are intuitive and easy to make. The included pod and 6' cable for the control panel make it easy to do a custom enclosure.

be aware that they appear to be overrated as to how many KW they can supply to the load (motor). I had to triple the size of the inverter because the first one would not do the job, although it was rated to have more than enough output for the application. You may want to discuss your intentions with the manufacturer's tech support staff before making a purchase, or simply select a unit that is double or triple the size of what you would typically use for a given load.

Bought it because it had some features that the recommended one didn't have and it seemed to have real positive reviews. Today I wired it to a old 3 phase drill press. The instructions could have been a little better and the terminal board lacked the grounding symbol. So I had to chance that the one not used was for the ground. The outer case could have been a little more less flimsy as well. But after all that, it works as advertised in converting 220 single phase to 230 3 phase. Buyers should be warned that most VFD's will store energy for a few minutes after disconnecting from power, hence you should use a shielded plug if not wiring direct. There is a risk of electricution if unplugging it too soon and touching the male ends of the plug-in. Basically; if the display is still lit up, it still has energy stored.

The device works well and smoothly controls the speed. Nice braking stop and soft start. I had a few issues in setting some of the programming parameters and the Tech Support was Excellent! There is a little time delay due to different time zones but they gave me clear and correct instructions on which parameters needed setting for 60Hz in the U.S.A. (P001) and to increase the stall power a little to help when resawing large hardwood pieces. Once adjusted it was able to deliver the needed current to do heavy cutting and the VFD did not noticeably heat up or other wise cause distress. Best of all, the modified program settings will be retained even if there is a loss of power to the unit. A very good VFD for the price, RECOMMENDED.

There were several minor things that they could change that would make it much better. Some of these have already been noted by others.

- The speed knob is minuscule. Not a big problem for me but could be better
- The stop button is also minuscule and close to the start button which is an issue. I have it installed on a bandsaw and an easy to see/reach stop button is important. I will later modify it with an external larger lever that pushes their small button.
[UPDATE: Look at the uploaded photos of the larger stop button that I made. A simple flapper attached to a wood block that I screwed to the backer board by the VFD. Note that the rubber foot used to press the VFD stop button has been trimmed so the full height is right into the corner. I was going to add a small, weak tension spring but I find it is easier to be able to flip it out of the way to get to the start button and then flip it back in the ready position for stopping. Easy-Peasy fix and it works well, easy target to hit for stop.]
- The terminal block is WAY too small. Maybe OK for small fans or something with 16 gauge wire but trying to connect 10-gauge wire was a challenge. I ended up having to grind down the sides of the eyelets to make them fit in the tiny slots in the terminal block and attach with the metric equivalent of ~8/32 screws. This needs to be made much larger!
- There is no connection box or strain relief for the connection wires. There is just a rubber seal on the bottom that you slit to push the wires through. This leaves the wires hanging off the terminal strip which is a recipe for disaster with 230V. The leads hanging down are also exposed outside of the external sheath of the cable, also not good. I tweaked up some wire anchors with wire ties and I'll later make a shield box to go over it all. Again, including a terminal box on the bottom with standard hole for wire anchor and strain relief would be a great improvement. This could even be an add-on piece so the user could decide to use if needed.

I installed on machine tool with 2 hp. motor and Unit is 18 mts. old now, and works well, never figured what connector style is used on extender ribbon cable, close to jst but no cigar,I wish they could offer different cable lengths but they don't. Gosh, for the price it is a great setup.
