Lathe VFD 1: How to wire a 3-Phase motor and VFD

Today, we're starting on a 3-phase motor and VFD upgrade for the Grizzly G0602 lathe. We'll talk about the motor and VFD and wire it up on the bench for testing before we tear into the lathe.

If you'd like to do this upgrade on your lathe, here are the parts I used:

Clough42,
I would like to thank you for your efforts on the video you produced of the VFD installation on your lathe and the subsequent video of the drive RF noise mitigation methods you used, reference your videos from 4 years ago.
I used the information from your drive RF noise mitigation method to great effect with an Automation Direct GS2 drive I installed on a bench top mill. This drive produced conducted as well as radiated RF noise into the AC and DC systems. This noise caused an IGgaying DRO to lose its position when the drive motor was running. I installed the same EMI filter on the drive input and ferrite toroid’s on the drive output to the motor as described in your noise reduction video.
I have also installed a Teco 2 HP drive on a lathe project. Thank you for the detailed look into the drive manual. Very helpful.

You took the time needed to explain clearly how this setup works. Your camera shots show very clearly how you have wired up the VDF and Motor. A lot of time has been put into producing this excellent video. My thanks to you Sir!

Great info, straight to the point, clear and consised, and no unnecessary tangent stories. Video is 10/10. Got yourself a new subscriber.

Thank you very much for this superb video. The VFD in my Powermatic wood turning lathe died a few weeks ago and I was very apprehensive about replacing it. The replacement part from the manufacturer was $650. With your video, I bought the correct new VFD for $230 and successfully installed and programmed it myself.

An exemplary work in how to produce a video and how to clearly and unequivocally deliver technical information into understandable terms. Thank you!!

I just saw this, 5 years after. I’ve replaced a number of motors with 3 phase inverter motors. After having used a number of different VFDs and motors, I’ve settled on these TECO/Westinghouse VFDs and their motors as well. I’ve found them to be easy to program, some are more confusing to those not experienced in this. The motors are made very well, and you know they work together.

There are different types of VFD and different types of inverter motors. Make sure you get those designed to work together. Generally, an inverter motor is constant torque at and below the rated frequency, down to some specified frequency, and then constant power above that to the max frequency. So my 2 Hp motor, for example, is constant torque from 3 Hz to 60 Hz, and constant power from 60 Hz to 120 Hz. Be careful when setting adjustment compensation for constant torque. Don’t be tempted to go right to the highest level, which is usually +50%. Stay close to +20-30%. Your motor may overheat otherwise unless you have a high overload factor.

At any rate, there’s a lot to this, many adjustments you don’t have to do. These VFDs have intimidating manuals for the uninitiated. I’m going now to the second video to see what he did. And, by the way, program the VFDs BEFORE attaching the motor, that’s a must. A beginners mistake.

As others have said, very professionally done, well explained, and top notch camera work. 10/10!

Thanks James! My 602 is starting to make those clicky sounds in the motor and I've been wanting to go to variable speed anyhow. Appreciate the hard work you put into this and sharing it with everyone.

[kcmorenachos]

As an electrical engineer, I loved every second of this. UL listed! Surprise, surprise.

[westweld]

Hey James just want to say I've watched this video every time I've needed to wire a vfd and its the best one on the internet.

[duane]

wow you look so much healthier in your newer videos, amazing work!

[davidparnell]

WOW...so logically articulated step by step...one of the most educational technical videos I have viewed! Learned a lot and THANKS.

[larryhilton]

Thanks for your VFD videos. I purposely bought a Teco L510 because of your clear videos. I’m refurbishing an old Delta 3ph bandsaw and installing the VFD on the saw. The manual is tough to follow since this is my first time setting up a VFD. Your videos really helped. Thanks.

[markreed]

THE BEST EVER VIDEO I HAVE EVER WATCHED ANY I AM AN IDOT AND I CLEARLY UNDERSTOOD EVERY THING CLEARLY BRAVO SIR EXTREAMLY WELL DONE FAULTLESS PERFECT I CANT BELIVE I HAVE LEARNED SO MUCH I DIDNT KNOW 3PH MOTORS AND VFD, S PROGRAMING AND WIRING

[HomebrewHorsepower]

This is exactly the video I was looking for. Simple enough for a novice, but detailed enough to be educational. You've earned yourself a subscriber.

[dwaynes]

Great video thank you. never seen a label like that before. my connections as follows; 4-5-6-, 1-1-7, 2-2-8, 3-3-9. I wire in over 1000k motors in a year.

[SRED]

Well, I'm really late to the VFD on a G0602 party. But when I ran across James' videos, I knew I had to make the jump to a VFD. The way James breaks everything down is clear and concise. Excellent content James! I got everything ordered and made the conversion. It works perfectly as in the videos. My next step is the ELS conversion. I have most of the parts already, just waiting on the Texas Instrument developer board and the cogs from China. I can't wait to get rid of all those nasty gears. Well done James! Thanks for your excellent content! You earned a new subscriber!

[shamanking]

you are using a single phase to 3 phase vfd.
when I watched some of your videos i had questions; I thought you were using a regular vfd but now makes sense .

[MavsMegaFan]

thank you soo much for taking the time to make this video and explaining everything so well

[mikevdb]

A very clear and imitable project. Thank you so much for sharing this.
