arrived on time tracking poor

I bought this to drive a wood splitter screw cone. My motor is a 3 phase 7Kw. I haven't made the machine as yet but I did hook up the VFD to test it and it works fine off load. I can vary the speed fine. Off load it's only drawing 1 amp off a GPO. The real test will be much later when it's crunching firewood and drawing 30 Amps. For the time being I'm pleased with the price vs. apparent capability.

Great buy, using it to control a 10jp mixer. Overall quality is great. Planing to buy another one soon.

We install this on an iron worker with a press beside it . We switch between the 2 . We had a motor ph that went out and they wanted $1200.00 to rewind the motor. This unit work great. Just wish they had a better manual. it too 2 hr. to install and 3 days to get someone that could understand how to program it

Bonjour, malgres des informations pour les réglages impossible de mettre en marche mon pont élévateur model DL240/3 voltage 400V/3PH/50Hz, la descente est hydraulique. Possible d’avoir un schéma de branchement et le bon réglage des programmes. Je ne sais plus quoi faire.

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.
