Customer Reviews for VEVOR VFD 7.5KW, 34A, 10HP Variable Frequency Drive for 3-Phase Motor Speed Control

I'm very happy with the VFD, it powers my 3 phase 220 lathe and set up was straight forward. I height recommend it.

There is a word count limit so I am giving you the basics hope this helps mine now reads in RPM and it runs great I set up a lower limit of 12000 rpm so my air cooled spindle does not over heat.P01.10 has to be inputted first. Auto tune is required especially for a cnc spindle(otherwise it could damage it auto tune figures out your winding resistance and specs) My name plate Spindle settings(use your own to set up): Max freq:300hz Max Rpm 18000rpm Max Current:13.5amps Max Power 4kw Put settings in then do auto tune then put lower frequency limit in last if needed.. Switch two wires Of UVW to change rotation if required(verify rotation when doing auto tune and verify again after because it may need changing again bug maybe). Do not start motor until after auto tune done(auto tune requires you press run to start it though). In totality here are the settings(mine yours may differ): P01.10=300(Maximum output frequency 300hz in my case as on spindle name plate) ) P01.08=300(Preposition frequency 300hz in my case as on spindle name plate) ) P01.12=300(Upper Limiting Frequency 300hz in my case as on spindle name plate)) P01.01=0(Motor control mode in our case Speed Sensorless Vector Control) P01.17=10(Acceleration time in seconds) if set too low and you will trip on current overload P01.18=10(deceleration time in seconds) if set too low back emf will trip vfd P02.00=1(motor type variable frequency asynchronous motor) P02.01=4(rated power of motor 4kw in my case as on spindle name plate) P02.02=220(rated voltage of motor 220v in my case as on spindle name plate) P02.03=13.5(rated current of motor 13.5 amps in my case as on spindle name plate) P02.04=300(rated frequency of motor 300hz in my case as on spindle name plate) P02.05=18000(rated speed of motor 18000rpm in my case as on spindle name plate) P08.03=14(led displays parameter 1in Operation status load speed display) P08.03=14(led displays parameter 2in Operation status main frequency X display calculates rpm value for display) After programming start an auto tune: P02.37=2 (press enter then run button) To set a lower frequency/rpm limit(do this only after auto tune is done it needs the full range to tune): P01.14=200 (12000rpm/18000rpm X 300hz sets the floor at 200hz or 12000rpm) In case you need to start over and reset to factory defaults: P17.01=1 Leave a reply if this helps :) As for DI,Do, and PWN inputs that's going to be a you tube video..

Works fine. I was skeptical at first but this thing works. Kind of impressed me.

Runs a 7.5hp 3 phase air compressor and doesn't skip a beat. Programming is confusing at first but there are many videos available online for similar units that can get you started.

I bought a hanyang inverter first and it Constantly gave me errors.. I returned it and bought this vevor.. This vevor inverter works flawlessly for my 10hp screw compressor.. I am very happy with it.

I am using this vfd to power a 1947 Monarch 10EE lathe . And it works great so far. Shipping was fast. Easy hook up.

I'm using this VFD to power a 10HP Marathon Globetrotter motor that runs a 6.2 GPM, 2,300 psi pressure washer pump. I was skeptical because of the comparatively low price, but this thing is every bit as good as these other reviews say it is. The documentation is not good, but it's worth the effort to figure it out. I have it programmed to soft-start from zero to 1,768 RPM in 5 seconds and it works perfectly. My only complaint is the electrical connections. The terminals aren't protected too well, there's a plastic hinged cover that sort of shields them, but 240VAC should be enclosed in a box or something more than this. Won't stop me from buyng another one though as soon as I can think of another use for a 3 phase motor. Great deal.

I bought this for my 18/25 mazak lathe which has a two stage 7.5hp motor. I couldn’t use a static phase converter for this type of motor and a rotary phase converter was way to expensive. I am extremely pleased with this vfd. I was a bit skeptical that this would work because the price was so low but it has proven very useful. Thank you Vevor for offering a great product at a reasonable price.

Works as well as any I've seen. The product isn't the smartest VFD on the market but for the price it does a good job. Have it wired to my custom 60T hydraulic press and run a foot switch to it. Probably not worth 5 stars because the housing is a little fragile in my opinion, just low grade plastic to hold those huge wires, but I gave it 5 stars because VEVOR sent me a broken one and their customer service department tried 3 different times to help me fix it (troubleshooting, a new part, and eventually a new one) and I value customer service like that.
