Customer Reviews for VEVOR VFD 4KW，18A，5HP Variable Frequency Drive for 3-Phase Motor Speed Control

En el primer arranque con un compresor de dos CV estalló co una castaña y ahora no enciende ni la pantalla

Le convertisseur 4 Kw ne fourni pas l'Energie nécessaire au moteur de 3 Kw de mon compresseur: Err 1 systématique malgré divers paramétrages et montage en triangle. Le moteur fonctionne correctement sur le triphasé du secteur. Je souhaiterai l'échanger contre un 7.5 Kw mais le support m' envoie des consignes inutiles en anglais et ne répond pas à la possibilité de faire l'échange.

Este un produs chinezesc care nu își merită bani. Scrie că scoate 4 KW dar nu depășește pe unu de 1,5 kw, o problema și mai frumoasă e că nu ai cu cine să vorbești și nu poți face retur ( procesul de retur e aproape imposibila). Cu siguranță nu recomand vevor

Obtained this VFD to operate a 3hp Delta Unisaw with a 3phase 220V motor. The VFD does not provide any "enclosure" for connection of input power or 3-phase output. So I utilized a general purpose enclosure underneath the VFD to connect the conduit and bring the individual conductors to the VFD. That enclosure needs to have ventilation to provide for the fans built into the bottom of the VFD. How the VFD is constructed pretty much requires that the VFD be mounted in a vertical orientation, in order for the fans to effectively cool the heatsink. No mounting position requirements mentioned in the instructions. The terminals for connection to the VFD are a screw with a washer under the head. The best connection is a 6mm / 1/4" wide forked spade, although a solid conductor up to 10 guage can fit. If using a stranded conductor, it would be best to solder-dip the conductor for safe and effective connection. The screws for connection are quite short, only screwing out about 4 turns before totally unscrewing, and theres no "stop" to prevent one from totally removing the connection screw. Then, the design of the case is such that it is very nearly impossible to get a connection screw in once removed. Once those installation challenges are overcome, the VFD works great. Press start, and it takes 10 seconds for the motor to gradually come up to speed. A turn knob allows adjustment of speed. In my application, a shop table saw, it would be nice to have big, tactile buttons to push for start/stop, especially the stop. The front panel of the VFD has a membrane keypad, that one must look at and very carefully touch the needed button with a fingertip to get start or stop. There is the provision built into the VFD to connect larger pushbutton switches and relays, to implement more shop-safe start/stop start. Overall it accomplished what I needed, and once I adjust to the slight inconvenience of needing to be more diliberate and careful in turning on and off, will serve very well.

Spent literally a week in shop and using all available resources to figure out why unit will not save p50-p55 x1-x6 settings. Saves all settings and changes except those which make it very limited in what can control the vfd externally. We just wanted to add an intermittent switch for both start n stop but that is impossible. So far chat gtp has been the best resource for programming. Shares that vevor have hidden values for saving to eprom chip. . I was unable to find the setting. We are now ordering a Hitachi vfd that is triple price but wil do momentary switches and save settings. We do have another vevor vfd on a conveyor system that works great so not sure why this one is so limited. It will work but note the x terminals will reset when you turn off power. Shop wisely

This product is working except I have bought other products such as the 25L sausage stuffer 2 months ago and Vevor support is non existent given the product design is at fault. Basically don't plan on any warranty support, You buy it and it fails plan on throwing it away.

Lo compré para poner en marcha un aparato de sierra trifásico de 3 kw, arrancó y comenzó a funcionar, estaba encantado, hacia varios años que esta maquina no funcionaba por tener monofasica en mi nuevo taller, pero aumente la potencia para ver el pico de velocidad que alcanzaba y.... estallaron las fallas de valencias.... pego 4 truenos el gordo y la mascletá, ardió como la tea, se fini. No lo recomiendo dinero tirado.

I cannot make it work because the instructions are so poor. They do not provide information on what all the parameters are or what they should be set to. I am not an engineer and there are no YouTube videos for Vevor vfd’s. I should have gone with a big name brand for the instructions they come with. I have no idea of the quality because I can’t make it work. The features are unidentified so I can’t use them. Ease of use, no. I cannot make it work without sufficient instructions on how to set it up.

Probleme bei Parametern, würde gerne den Umrichter zurückschicken und einen anderen haben. BIN der Meinung das er nicht inordnung ist. Mit einem anderen ist ok.

Worked few minutes, then blew up with smoke. There is absolute no money back guarantee. They have their internal system theatre for issues/problems which hides consumers rights totally. Not recomending Vevor to anyone.
