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

I’m leaving this review to help anyone in a similar situation to myself. I purchased a 3-phase CNC lathe (a Southwestern Industries Trak TRL 1630SX) but only have single-phase power in my shop. The lathe has a 10HP motor, and I was able to set up this VFD in about 30 minutes and get the machine running smoothly. You’d never know it’s not running on true 3-phase power. I’m particular about buying quality tools, so I was initially skeptical about this relatively inexpensive VFD — especially since name-brand units cost several times more. However, after using it for a month, I’m completely satisfied and wouldn’t hesitate to buy another one. The motor runs flawlessly, and the setup process was straightforward. I recommend watching a few YouTube videos for setup guidance — it makes the process even easier.

Used to drive 3 phase compressor. Worked like a charm. Been going over a year and no issues.

Price - was way below average from any other brand. Easy to use - I had an electrician wire it in for me he was able to find a video online for the individual specs needed. Features- way more than what I needed.

Used this to power my cnc mill and it works perfectly.

Est ce que quelq'un peut m aider a le programmer pour un pont triphasé svp Zéro six ciquente neuf zéro six rero un ciquente quatre,merci

Utilise pour pont triphasé sur une installation monophasé. Commande via le variateur de fréquence ainsi démarrage progressif possible. La notice est peu aisée à appréhender c’est un point à améliorer pour être accessible aux moins « acharnés ». Il reste à voir dans le temps…

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.
