The manual could be more detailed on the parameters. The manual does not list all the parameters in the unit so im not sure if they are correctl set. . Im only running a straight 60hz motor with no adjustments to the Hz. For the short time using the VFD it is working perfectly. Much cheaper then buying a rotory phase converter.

Omvormer uitgebreid getest en met de menu functies goed te bedienen en installeren. Wordt hier gebruikt voor een 1,1 kW draaistroommotor op een kolomboor. Heb wel een ster schakeling toegepast omdat in driehoek (delta) de motor te warm wordt. Volgens de manual zou driehoek schakeling mogelijk moeten zijn? Blijft voldoende koppel over om ook grote boren met een rpm van 200 te laten werken. Een technische vraag over de omvormer werd binnen 24 uur behandeld door de klantenservice en verliep over drie afdelingen, was erg onder indruk.

I am surprisingly pleased by this VFD, so much I bought a second one for a backup just in case. This works great on a small milling machine with a 2 HP 3-P motor. The only complaint is the documentation is terrible. They instructions don't explain what programming features actually do. And the nomenclature (that's being nice, some of it is gibberish) is poor. But once you figure it out by experimentation, you get the drift. For the money, this is a nice unit. If you have a coupon or discount code, all the better. I mounted mine in an older tool post grinder box and moved the display out to the cover. I also transferred the controls to a separate box where I used momentary push buttons to control on/off and reverse, but the programming and potentiometer is still on the original display. This unit has surprisingly many ways to farm-out controls to remote switches using the X1 - X6 and SP1-SP2 terminals. Of note, the unit shows a terminal with a 12 VDC output and the manuals says that's 15 VDC but both are incorrect. The output on that B+ is 13.8 VDC, which I use to power a digital hall effect tachometer. Vevor needs to do a better job with the documentation otherwise, I'd recommend this unit for small machines with 3-P motors.

arrived promptly and well packaged. Works well and was very easy to programme, lacks some of the finer controls of the more advanced units (which are not really needed) but this aids in making the programming simpler , in fact you could use it straight out of the box and have it work. One essential thing that needs to be added is a cable support for the mains wiring. I added 3 cable glands on a right angle bracket mounted underneath the wiring terminal strips, easily done and adds a lot of safety.

First one we received had a malfunction, we returned and they promptly sent a new one which has been working fine.

Tutto ok

This is a good unit for the purpose. Well built, great price. However ... I see no reason VEVOR would ship a 50-cycle unit to the United States. The manual instructions to change to sixty cycle are worthless. I see no information on changing the ramp-up and ramp-down times. No information regarding if those times are necessary soft start Parameter change instructions need to be written for the average user not a technician.

Overall, I am very happy with my purchase. The main difficulty is the manual. I am at odds as to what and how to wire and program the VFD. Maybe I should blame it on me as being new to VFD's, but I don't think so. Why is it so difficult to write instruction manuals for the layman. This happens quite often. Which makes an excellent item a burden to use or assemble. I can guarantee if the if the manual was written properly, there would be fewer, if any, need to contact you . Your product is excellent and I wouldn't hesitate to recommend it.

Works great for 3phase testing

If you've never used / programmed a VFD before than you will probably struggle getting this setup. Luckily I was controls engineer right out of college so I had a good idea of what was required. The instructions are complete garage. The translations needs a lot of work. Use the Googler to figure out what what the parameters are. Calling them instructions is a reach but like I mentioned earlier, I had a good idea what was needed to get it running.
