Kundeanmeldelser for VEVOR VFD 7,5 kW, 34 A, 10 hk variabel frekvensomformer for 3-faset motorhastighetskontroll

I didn't use it after fixing it last time, but when I tried to use it again, the three-phase power supply didn't work. I reset it to p77 (54321), but the secondary three-phase voltage didn't come out.

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.

Tutto ok

The VFD works very well once properly configured and has no problem driving a 4 kW spindle at 300 Hz and 18,000 RPM. The unit offers stable operation, smooth acceleration and deceleration, and full external control through Mach3. After configuration, spindle start/stop and speed control work perfectly. Pros: Stable performance Reliable spindle control Compatible with Mach3 Good value for the price Cons: The user manual could be improved. Some parameters are not clearly explained, making the initial setup more difficult than necessary. Overall, this is a solid VFD for CNC applications. If you have some experience with VFD setup, it performs very well and offers excellent value for money.

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.

So far, the unit has performed as expected. It doesn't have some of the advanced features like the big name brands, such as sensorless vector mode. The real problem is the documentation. Parameters are poorly explained. For example, there is no documentation related to adding an external potentiometer like the max kilo-ohms. Then, P73 and P74 set the "Maximum/Minimum external analog" values. Trial and error let me find values that worked with my pot but it was very much a stab in the dark. Overall, though, it provides the key features of a VFD at a very affordable price.

I purchased this VFD to run a 2HP 3-phase motor in a vertical bandsaw. There is a very narrow range of frequency (20-33 Hz) that it will start the motor. Selecting lower than 20 just gives a buzzing sound and doesn't start. Selecting higher produces an error (seems to trip a breaker) and shuts down VFD. When selecting in the narrow range mentioned above, after the motor starts, then I can increase the frequency to full levels. I wasn't sure what to expect but I thought 5HP VFD would be sufficient to start a 2HP 3-phase motor, but I guess I should of went bigger??
