Customer Reviews for VEVOR VFD 2.2KW 10A 3HP Variable Frequency Drive for 3-Phase Motor Speed Control

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.

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.

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.

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.

Inverter essenziale: fa quello che deve e vale quello che costa. Se siete abituati a inverter di marche blasonate europee o americane scordatevi i menu infiniti di configurazione parametri. Consiglio: per applicazioni gravose e carichi meccanici all'albero motore non costanti provate varie configurazioni sui parametri di TORQUE COMPENSATION fino che troverete un buon livello di servizio.

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??

Fin den.

VFD worked great for a month then blew breaker. It was replaced with no problem and the new one is working great! Manual is a bit difficult to understand some of the parameter settings but customer service sent a video that explained it well!

1 week in and its performing well running a 7.5 hp compressor. programming for 60hz power took a few minutes but there is lots of videos to watch. Its running inside a vevor 20x16x10 enclosure.
