How to: Wire a Cheaper VFD for a 2x72 Belt Grinder Build

[@d.comeaucustomknives2677]

Very good Brian. A couple of points of interest. Swap any two motor wires (W, V, U) to get the motor to run in the opposite direction. You can program the acceleration time to "ramp up" to target speed. I use 8 seconds so I can adjust the tracking if needed before the belt gets up to full speed. A lot of these low cost VFDs will display Hz or RPM. You will have to program the number of motor poles, typically 2 or 4. Reading the manual, even if partly in Cantonese, can be pretty helpful. Of course, keep it cool and away from the metal dust. I have a couple of these and a KBAC-27D. I am happy to say they are all working good. Knock on wood. Cheers!

[@HouseMadeUS]

Awesome Dan, thank you so much for this info, AND all the info on your fantastic website. That is where I learned all of this stuff from. YOU are the MAN! :) Hope you are well my friend.

[@grimmner]

Im borrowing this post hopping to get a good respons(: Im Looking at a grinder with an equal setup and o e thing Im interested is exactly being able to change the direction on the motor to ge the belt going backwards, more expensive modells seems to have this feature but this cheap dont to my understanding. My understanding of electrobics aint the best but i had it also in the back of my head that switching the wires would accomplishe it. Is there a smart way one could wire that up to a single switch? Like having double wires going to the motor and by a turn of the switch change the polarity. Perhaps it would need 2 switched that both world as on switches one for forward and one for reverse. I do have friends that can help me do the actuall work so that i dont electrocute myself but they dont have experience from this so hopefully a can get some guidence here If i understand the possibility correct or not(:

[@eleengineer]

​@@grimmner consult your specific manual on external control options. Swapping polarity at the motor is not typically recommended with a switch

[@adamg1408]

Looks like the wires to the motor would be: Black: T3, T9 White: T1, T7 Red: T2, T8 Bound together: T4, T5, and T6 This is to help others that are also color blind. I had a very hard time telling the green (ground) and 'red' wires apart.

[@HouseMadeUS]

Thanks Adam, very helpful! 👊🏻👊🏻👊🏻

[@roywilson9214]

The cheaper one on Amazon

[@AIActionFun]

Thanks for this Adam. I just used this to wire up the motor. I now have a working VFD and motor!

[@alk5749]

Thanks for this, all my motor wires are white, but labeled.

[@MountainDewBots]

Life saver man, my motor came with all the wires in red so its been a guessing game since. Luckily they are all labeled so this will save me more time and frustration.

[@RTOHIO]

You have barely scratched the surface of the Chinese VFDs which are very similar but have a myriad of programmable parameters to allow starting at a low frequency for a short time (you select the time) after which the unit can switch to a second higher frequency or directly to the maximum run frequency. The parameters can be altered to select how long each startup frequency stays in seconds before the next frequency kicks in. The maximum frequency can be significantly higher than standard American 60 cycles/second. Be sure your motor can handle the higher frequency. Many of he units have a built in Braking Resister to allow you to select a braking time. In addition they almost all have the ability to add a emergency stop switch, run, reverse, and other things. The little control panel buttons are very small to find in an emergency stop scenario. There are over 100 parameters and the manuals are written by people speaking english as a second language, although very good , they refer to parameters that are not always what we would call them. I have used these VFDs for 5 years now running my Bridgeport and 2 x 72 grinder (by a design that I will replace with your design). I have had only one fail but support from China is not good. I have one coming that will support a 30 meter cable (included) so I can mount the unit in the nearest clean environment, far away from metal dust. My Bridgeport VFD supports a 6 meter cable and I mounted the box about 10 feet above the floor, the control panel below my DRO. Has been successful for three years and counting.

[@HouseMadeUS]

Yeah I agree, I see the instructions and there is so much to learn. Also I was looking at the HZ rating and my motor should only go to 60 so I will have to adjust that. It said I was up to 65. Not sure if that will hurt the motor or ??

[@jeanrobertwongtitshing8227]

I find it very interesting, now if there is a way to pull out a wire from the connections of the VFD (most VFD has that option too) and connect to a potentiometer in a separate box and easy acessible to your place of work) of a big knob. Sometimes when you are doing mechanical works with the gloves on your hands, it much convenient to access the knob than the small switch on the VFD.

[@gwcstudio]

I have been grinding blades for 5 years with a 2x72 that runs at the same speed. The first thing you gotta ask yourself before you go VFD is if you need it.

[@HouseMadeUS]

I need it. Saves time and material. But that's just me. I know not everyone does.

There are 110 VFDs that upscale 110 single phase to 220 3 phase. They work great!

Looks remarkably easy. Can I ask the reason you used 10 guage wire for the input? Its only a 110v, single phase inverter, would an ordinary extension lead do the job just as well?

I've since dropped it down to 14 gauge.

I got this same vfd for a 1 1/2 hp baldor pedestal grinder, i have 220v plugs ran in my shop on a 20 amp 220 breaker i was going to make a plug to plug into one of those outlets i dont think the amps go anywhere near 20 amps atleast for the grinder but i see you used 10guage wire is this bc the vfd draws 20amps or more? Or is it just bc of the power source you have in your shop? I also bought the plans for your belt grinder awhile back, been slowly accumulating material to build, still trying to figure out how to get the cnc cut list opened, but not a big deal i might do it all by hand anyways, cant wait to build it!! (Update) i see the vfd only draws 12amps at most so i should be good with the set up i already have. Thanks for the video!! Awesome that the cost of build has significantly dropped!

[@HouseMadeUS]

I use 14 gauge now for most VFDs. 12 or 10 for longer runs. The DXF files can be opened with Fusion 360 or any CAD program. Only really for CNC use though. Cheers and thanks!

Does it matter which on the motor? If I switch black and red or black red and white? My motor just has L1 L2 L3 so do I just do whatever comes out the vfd? I’m using this same vfd and a similar motor but the wires are all grey and numbered

[@andyatwell6891]

His motor data plate shows wire color with the number. Blue T1, Brown T7 White T2, Red T8 Orange T3, Yell/Blak T9 4,5,6 tied together. Then he has wires from the motor installed on the VFD White to W Red to V Black to U. But the red and black are reversed on the diagram at the upper right of the video from Dan at DC knives.

That is correct.

[@Austinificationify]

Was hesitant to make that upgrade from my treadmill dc motor/controller to the kbac/ironhorse setup but its made a world of difference! Thanks for the tips! I ran into an issue where the attached mounting bracket on the ironhorse motor relative to my dc motor caused the motor to protrude about two inches further out, throwing my whole setup out of alignment. Had to do some creative modifications to my grinder motor mount to accommodate the new motor and have it align with the platen and tracking wheel.

[@njbaquatics4827]

Instead of grinding those connectors and turning them into what you need why don’t you just buy the right connectors which are the fork style ones. And they’re way easier to install

[@HouseMadeUS]

I do that now. I was using what I had back then.

[@libertyordeath1287]

Just got my revolution kit last week and motor came today (still waiting on the Chinese vfd). Couple questions: 1. I noticed on this vfd and motor you used 10 and 12 gauge cables and on the kbac wiring video you used 14 gauge for both whips, I assume 14 gauge is good for the Chinese and motor? 2. I have a 50 amp service I use for my welders and plasma cutter, would I be ok to use this for the grinder as well or should I put the grinder on a smaller breaker?

[@HouseMadeUS]

Yeah the 14 gauge works great. The motor and VFD don't pull a lot of amps so 14 gauge is perfect.

[@libertyordeath1287]

What about the 50 amp breaker?

[@BenAnderson1979]

I bought this VFD for my grinder build (Gen 5), but I'll be wiring mine into 110v instead of 220v. What difference, if any, is there with the wiring instructions you're showing here?

[@jjforeal2]

13:22 I have a similar vfd and I don’t think it’s 32% power. I think it 32hz out of probably 60-65hz which is factory settings top end for these guys. Never mind while I was typing you caught it 😂

You sound like you know what the hell you’re talking about. So let me ask you a question. I’m trying to set up a 1940’s drill press so I can drill steel and wood. I have a 1/2hp 3 phase motor I want to use. Here’s the question: if I have a converter which can step up or down voltage do I also need a VFD?

I’m getting some wild “vibration” as the motor speeds up, I am running program p00.00. Didn’t see the same with yours, also my VFD only goes to 50 hz out of the box . Any suggestions?

The vibration is most likely coming from a bent shaft in the motor. Also make sure you set the VFD to 60hz. On my VFD there is zero programming required. Wire it up and go. Good luck. 💪🏻

Hey Brian can this set up work with 110 volt I do not have 220 in my shop

[@richardtullius6419]

House / Work I thought that might be your answer but not a good idea, it’s about circuit protection, not about what is convenient. I love your grinder and expect to buy the kit in the very near future so I’m not here just to rag on you. You are looking for perfection in your grinder but you need to understand a little more about the electrical side. The NEC says the receptacle must match what is being plugged into it, and the circuit breaker is sized by the receptacle amp rating, it’s about safety and fire protection, plugging a 20 amp motor into a 50 amp circuit means the motor will burn to the ground long before the 50 amp circuit breaker trips. Please call a electrician and have them install the proper receptacle. This advice comes from a retired electrical contractor with 40+ years of experience. Keep the videos coming, keep improving your grinder.

[@HouseMadeUS]

Hi Richard, thank you for your help man. After I read this I swapped out the 40amp for a 30 amp and made a dedicated circuit for the grinders. That way I am not sharing the plug with my bigger gear. I appreciate you taking the time to comment and give direction that I can use! Many Many thanks.

[@markkoons7488]

More than forty years ago I started buying 3 ph equipment, most of it obsolete industrial machines. At first I synthesized 3 ph with a home-built rotary converter. I added utility-provided 3 ph as soon as I could afford the installation. That made sense when I was able to buy 3 ph power at residential rates. Now, in my new shop, the cost of 3 ph power is sobering. There is a monthly minimum several times greater than my actual usage. My store room holds more than a dozen perfectly good spare used motors none of which cost me more than $100 and that is a 15 hp Lincoln. The rest were $40 or less. Often they were free. Anyone wanting powerful, variable speed machinery ought to stick with single phase and outfit them with VFD drives.

Why such a massive input cord and plug? Full load with that inverter/motor will be 10-12 amps, which could be easily handled by 14 AWG (maybe even 16 AWG). Similarly, a 20A circuit (and plug) would be more than enough.

[@HouseMadeUS]

It’s what I had laying around. I wouldn’t go 16. 12 seems about right. Thanks for watching.

[@Stillpoint23]

No, 14 or 16 must not be used. The upshot of the comment below: 1) check your electrical system a) is the panel stab-lok, or federal pacific, in poor condition? Consider upgrading if so b) is your system wired with knob and tube or BX? Take steps to ensure that it's safe, especially K&T c) is your system properly grounded? See below 2) 20amp breaker is really 16 amps a) use 12 gauge (#12) wire, 10 gauge for long runs to mitigate resistance b) residential ckt breakers are not rated for continuous use, so #12 is recommended if not compulsory 3) Grounding a) at the very least, properly ground your ckt supplying your grinder, and bond your water heater if needed In my experience, 12g is the minimum on a 20a ckt. 10g would be better in order to decrease resistance especially if using a cord in lieu of hard wiring. 16 amps is 80% of 20a, and the VFD has a 12a output. Since residential ckt breakers are not rated for continuous use, it's best to over build for better protection from overheating. Furthermore, I would HIGHLY recommend taking note of both how old and what brand of panel you have as older homes may have Stab-Lok, or federal Pacific panels which are hazardous. One more point about older homes is many are wired with BX which technically has a grounding system, but many are not wired properly, and the grounding wire is so thin it's often broken. So, check your system thoroughly, and if tying into ungrounded or substandard grounding, at the very least ground the system you are installing by running a ground wire from your metal box to a water pipe then bond your water heater if it already is not. Sorry for the long winded comment, but safety first. I'll put the upshot at the beginning for those who would rather not read this all the way... 😜

Thank you for watching and supporting my work. 💪🏻

[@WesKerbs]

Thanks for the video! I'm about to upgrade my treadmill motor and was wondering if that Chinese 110 VFD in your link would work with the 3hp Iron Horse motor (the 2hp is out of stock until September or later). Thanks and keep up these great videos!!!

[@HouseMadeUS]

Yes that will work just fine the for the 3hp. Good luck and enjoy the power! 😁👊🏻

[@WesKerbs]

@@HouseMadeUS Thanks Man! I pulled the trigger! Sorry to bother you again but as far as the cords go: do I get a 3 cord and a 4 cord in 12 gauge like I would for the 220 or is it something different? Again, sorry for the questions... You rock.

[@HouseMadeUS]

I like 3/10 cord up to the VFD & 4/12 cord from the VFD to the motor. Enjoy. 👊🏻

[@WesKerbs]

@@HouseMadeUS You sir, are a gentleman and a scholar. Love your videos and really appreciate you answering my annoying questions!

[@paulmcgaffey9154]

Brian, what loss of power / speed can I expect with the setup you demonstrate? Would it be approx ⅓ loss? Thanksfor your useful video, Paul

[@HouseMadeUS]

I don't think there is a power difference at all. I still run this setup next to the KBAC units and it holds true. Still very impressed. ⚡️⚡️⚡️

[@Thibodeau_Knives]

Can you recommend a motor for that 110v VFD. My hook up is 110v at home.

[@HouseMadeUS]

At this time I only can recommend the 220 3 phase motors. It’s all I have tested.

[@workingclassdad1]

Is this video using the 110 vfd or 220 vfd?

[@HouseMadeUS]

220

[@ForgeandFairway]

Getting this vfd delivered tomorrow and motor on Monday! Can't wait to get it installed, thanks for the awesome video!!

[@HouseMadeUS]

Yeah man! Thank you Kyle! 🙌🏻 🤜🏻⚡️🤛🏻

[@fredastaire6156]

what amp is your wall outlet that you plug the VFD into? is it a 15A or a 20A outlet?

[@HouseMadeUS]

20amp. 👍🏻

[@mercwelds6450]

I bought the same vfd I hooked it up to my disc sander. And it worked but now it’s leaking some fluid and smoking? Faulty unit??

[@HouseMadeUS]

Yes definitely faulty.

[@mercwelds6450]

@@HouseMadeUS I ordered another one and rewired it and it hasn’t blown up yet so it was a faulty unit. I wish I could somehow show you the video I took of this thing smoking and still running

[@jdshear01]

Just got my Ironhorse motor and VFD this week...looking forward to getting it wired up next week!

[@burnyknob9502]

that motor is sold out but i found a good 1.5hp , my question is will a 1.5hp work on that vfd

[@HouseMadeUS]

Yes it will work.

[@alk5749]

Brian, did you program any of the “P” values and if so which ones?

[@HouseMadeUS]

No I leave the unit stock. Works great

[@comfortairtech5820]

Will it work with a 230V 3PH 3HP EXHAUST FAN MOTOR ?

[@HouseMadeUS]

Yes

[@scottydntno]

Can't you just use a 2HP 110 volt AC motor?

[@HouseMadeUS]

You can, but speed control is preferable for different materials. Definitely worth doing

[@CautionUnderFire]

So, the motor you list/recommend is for 220v. Would that still work with the 110 input vfd you list?

[@HouseMadeUS]

Yes, the KBAC will upscale 110 to 220 but you lose 1/2 HP.

[@CautionUnderFire]

@@HouseMadeUS thank you. What about the "cheaper 110v vfd"? The KBAC is out of stock, and while i hear the "buy once cry once" philosophy, I've seen good reviews on some of the cheaper vfds.

[@hagsmich]

Great video, I was sweating it until you made this video.

[@HouseMadeUS]

Great news! Glad it helped! 😁👊🏻

[@heliguy3062]

Great video Brian on the wiring for the VFD and motor electrical is not my thing so the info was great. I did read Richard's comment about the amperage for the power supply I do have 220 40 amp power in my shop for my welders and plasma cutter but will have a separate plug installed for the grinder.

[@HouseMadeUS]

Good idea. I agree with him on that. Makes sense to be safe always. 💪🏻😁

[@GrimL3]

Brian, love the channel, I've recently completed my first build, and it runs great! but when i run at low speed for an extended amount of time, like 15min , this VFD spits an overheating error. you think this is just something i'll always deal with? or possible faulty wiring, electrical stuff like that is way above my paygrade haha, i bought the cheap motor you suggested on Ebay, i haven't had the VFD long enough to be gunked up that much to reduce cooling

[@HouseMadeUS]

Might be a wiring issue but sound more like a cooling problem possibly a bad VFD. Have you tried just having a fan blow on it? Might tell the tale and help troubleshoot

[@GrimL3]

@@HouseMadeUS Thanks for the reply! i had the L1 and L3 wires from the motor on the wrong terminals to the VFD, also discovered my motor is slightly different in that its variable torque rating is 4:1 and not 10:1 so it doesn't like being slowed down for extended periods, since the wiring change though i haven't had the error code trip again, hoping for the best! definitely will be buying the Iron horse if i continue to see problems

[@williamoverton7265]

Thank you

[@HouseMadeUS]

Thank you! 🙏🏼

[@swordfish1120]

Good vid. I have an old 2"x72" Burr King grinder that I bought primarily for sharpening my personal EDC knives. Any big benefit of running a VFD for this purpose?

[@HouseMadeUS]

Is the motor a 3 phase motor? If so I like being able to control the speed of the belt. Burr kings are great btw.

[@swordfish1120]

@@HouseMadeUS No, I have a 1hp single phase motor so I'd have to buy a 3ph motor and VSD. I just didn't know if using this VSD setup has great benefit for sharpening knives and if its worth the investment?

[@pbservano]

I'm using the same VFD bought from Ebay for approx. three years now...It can also be programmed to install a remote switch, for start/stop. forward and reverse switch and e-stop. The parameters has to be change in the VFD. I install the control box close the grinder and place the VFD farther away from the grinder to keep the VFD sucking up the metallic dust from grinding. Doing so will increase the longivity of these cheap chinese VFD.

[@HouseMadeUS]

Good to know Pete. Thanks for sharing, did you have any info on how you programed the remote switch? I would like to take a look. Thanks again.

[@pbservano]

@@HouseMadeUS ....It should be on your inverter instruction that came with your inverter....First, you have to access the programming mode. See page 16 (Parameter Setting Procedure).... parameter P50 (x1 terminal), change to 19 for e-stop; P53 (x4 terminal) change to 5, forward; P54 (x5 terminal) change to 6, reverse; The forward and reverse should be on default 5 and 6 already...The only parameter you have to change is P50, default was 13 change to 19....On page 5 of the instruction, you have to purchase a 10 Kilo Ohms potentiometer, wired to com, Vl1/cI, and 10v/5v., this is for your frequency/speed control.... I ran total of seven (7) 20 AWG control wires for to the VFD. The terminals I am referring to are on page 5, see VFD schematic diagram, common, X1, X4 , and X5. I installed a separate box for 220VAC power. Ensure to programmed all parameters prior to wiring all switches. I had issues with the proramming when I had the switches in closed, and tried programming the parameters and the VFD will not store the data. The terminals are located on the top portion of the inverter. It is hard to see the terminal designation on the circuit board... Forgot to mention ..Parameter P10....change to 2; and P11...change to 2; Here's the link to my VFD powered grinder......kzbin.info/www/bejne/fJCseWhti9t9edU

[@jonathandehors2684]

Do you plan to show how to make a separate control box to wire in a potentiometer, forward/reverse and run/stop switch? I'm on the struggle bus lol

[@HouseMadeUS]

Hi Jonathan, this VFD has a separate control box already. It pops out and they even give you a 6ft long cord. All the buttons work. No need for anything more! 💪🏻😁

[@jonathandehors2684]

@@HouseMadeUS Yeah i was stupid and bought a Morphon one before you posted the video. And the control I have doesn't have a dial for the potentiometer, just arrows. And I'd like a large emergency stop. The low volt part isn't the same as yours, or any videos I find online. No worries, just thought I'd ask. Thanks for the reply

[@alhaah777]

What is that sophisticated belt grinder for? If I need to sharpen a knife, I can use a belt sander.

[@HouseMadeUS]

Metal fabrication and knife making mostly. 👍🏻

[@jrocks1971]

lol - Now there's a guy who doesn't need a 2x72. ;-)
