Super clear and helpful explanation. Thank you!!
AWESOME VIDEOOOO can't wait for part 2 where you show how to connect the digital wires and what are they for.
THANK YOU SO MUCH! Good video. I appreciate you sharing your knowledge.
Thank you so much for making this video 👍👍
Thanks! Just bought one of these!
❤❤❤❤❤❤❤ please 🙏 do more of these using different types of VFDs😊😊. Thanks 👍
Super Video Made Clear to understand
perfect vid dude in 9:41 mins. awesome
Great video
I've been running my VFD's on a 3/4 HP 3 phase 3,000 rpm motor.........I made a chart to indicate the actual motor rpm.........connecting it according to the video was clear.....thanks for your time.
Thanks for the info!
Good video
Cheers
Thank you for your video. I recently got a setup similar to this and was wondering if you know if there is a way to change the display to show RPM instead of frequency.
very huge Thank and thumb up for detail exlanation
I've tried it myself and had discovered that it can run both 2-phase (split phase) and 3-phase induction motors.
Thank you very much
After doing further research I noted the forth pin was connected to the ground and a cable that is shielded will provide the best results.
Cheers
Some of the spindles don't have the 4th pin connected to the body of the spindle. If your machine is grounded, you don't need to connect the 4th pin and some manufacturers will warn the end user to not use the 4th pin if the machine is grounded and the spindle is conducted to this ground (via the metal on the machine).
nice video and useful
i want to asking you something
ac servo motor have 4 wire 3 phase and the 1 for earth
can i wiring ac servo to vfd to get speed and directions only... no need the encoder
i mean open loop ????
thanks
Thanks for your part 1 wiring up VFD. Could you share the link to connect to open build black box?
Thank you for the video, my laptop that i use to control the cnc starting to forze when i turn on the spindle, do you know what happen?
Very informative ! Why you do not have to change the parameter of the VFD, like the 2.2 KW and max rpm of the motor ! Anyway , it is a very clear and through of showing the setup ! Thanks for sharing !
regards
Is it possible that you share the link of the second part?
Or you have a video with the connections and configuration by PWM
Thanks for your time and answers.
THANK YOU SO MUCH
Is the spindle a 3-phase unit and is the VFD 3 Phase as well. I have a 220 Volt/400 HZ 1.5 KW Air cooled spindle that I purchased online, but need to know what type of vfd it needS. I have one from an old lathe that we used for 220 Volt single phase to a 3-phase mill.. do you know if it will work..
Thank you so much!!!! I burned up a motor already with the "supplied directions." I'm still getting over that :( Anyway Thanks a bunch "Your videos are Great"
can you use 110v spindle on 220v vfd? are the spindles really volt rated or is it vfd dependant?
GREAT VIDEO CAN U POINT ME TO THE TRANSFORUMER YOUR USEING PLZ TY
Good video. However I would recommend connecting the spindle to the VFD using shielded cable and earthing the shield at the VFD end. This is really important for CNC systems to stop the spurious electrical noise causing problems with your steppers. Also it appears that you did'nt earth the spindle either, which is not really a good thing to do.
Thanks. I have been using shielding a little while after I made this video. Initially, I was testing the PWM from the computer to the VFD and noticed the value jumping around like crazy. Now I shield the spindle cable and I also shield the PWM signal cable. I've also seen some folks actually use ferrite to assist with the PWM signal cable. The wires are coiled around the ferrite to create inductance. I'm not sure how this helps, but if you or anyone could shed some light on this, I think it would benefit others.
Thks!!
@@PatrickHoodDaniel The ferrite core is known as a load reactor but it’s just an inductor. Motors on VFDs create a lot of harmonics and reflected signals (voltage spikes coming from the motor back into the VFD). These spikes can reach thousands of volts so the load reactor is there to limit the spikes and protect the VFD and motor
: :.((
The spindle must be earthed (grounded) for safety! Without en earth, a small breakdown in spindle winding insulation can cause the body of the spindle to become energised with a couple of hundred volts and killing someone. With proper earthing, the faulty spindle will trip the fuse, CB or the drive unit, keeping everyone safe and you knowing your spindle has an electrical fault. Earthing/grounding is essential to safe operation!
Would you try to apply 110 VAC input with 220 VAC VFD Model and use 110 VAC motor to see it working or not. The reason 220 VAC VFD a lot cheaper than the 110 VAC Model.
Do you have a link where you connect the wires to the digital input?
thanks
can i ask for the type of connector used in video or its datasheet
Do you have have any kits for a tool exchange system?
I have 30V 150W jager spindle and I want to run it using 220V input 400W Delta VFD L. I reduced maximum output voltage of VFD to 30V. By doing this I am able to rotate spindle on high frequency but I am not getting enough torque and when I stop spindle from VFD then over current alarm appears on VFD. Also spindle takes very high current. Please suggest if you have any idea from your knowledge perspective so that I can run my spindle using VFD instead of highly expensive spindle driver.
Sir I am engraver so I want much sharpness and clearty in my job work.so how much power and rpm suitable for iron sculpture design engraving.best quality finishing.please guide me
Thank you
You're welcome!
Hi there, do you how to set up Fuling DZB280 VFD by any chance?
In the video you say you have a 220 circuit with a N, L and G. In the US our 220V is (3 wire) L1, L2 and N (two hots and a neutral or (four wire) L1, L2, N and G. I have a VFD (with similar connections as yours) that I need to hook up. How can I hook the VFD to our power in the USA?
He used a standard 110v plug but wired it to carry l1 and l2 on white and black with the green acting as neutral, I would have used a NEMA 6-15P plug and the correct wire colors but essentially his works. However it could accidentally be plugged into a 110v outlet.
Thanks for the video. The video was very educative, however, I would like to ask some questions. First a background, I am setting a reactor for my PhD project and I need to run 2 pumps in variating frequences. As your video demonstrates, the motor/spindle runs only with the VFD and nothing else, correct? And for the installation, the power goes through the VFD and then connects to the spindle, so no further connections are necessary, right? Thanks a lot!
I've used a couple VFD's for other purposes and I'd say your assumptions are correct, just wall power -> vfd -> three phase motor. Nothing else (besides the appropriate kind of wires in between).
I followed you video but my spindal only revs up to 11620. Can you advise please?
Great ! do you have Set up part 2 ?
Here is one of them: ua-cam.com/video/0SLFuM4tzuU/v-deo.html
Hola, tengo un problema, en sentido FOR me va todo bien pero cuando cambio a REV empieza lento y se para. Porque puede ser? En FOR me gira en sentido antihorario y me gustaria que girara en sentido horario
una pregunta de novato, si 400mhz son 24k rpm 200mhz son 12k? se calcula lineal?, gracias.
Share the second part of this video please, how can i connect old breakout board to my 2.2kW Spindle VFD
Please Help me
Hi There, I did try with other kind of vfd who can also drive spindle but get a error on display P.oFF and no running or output voltage. manuel says nothing about it. Maybe you can, Thanks in advance.
Is a part 2 out? Thanks
Hi, I have just bought one of these to replace a different VFD that went BANG! ;) I have an identical spindle motor to your one in the video, I am concerned about getting the parameters on the VFD correct as I don't want to kill my motor! Is there any chance you could let me know what parameters you changed from the default values ( P06 for example defaults to 50Hz, but I guess you have it set to 400.) Any help would be greatly appreciated as I am desperate to get my machine up and running again! thanks in advance :)
Check out the CNCZone. I saw someone posted the working settings for that model.
Thankអរគុណ🙏
Is there a parameter to change the VFD's frequency from 50hz to 60hz ,
Or is this not required ?
Thank you for making this tutorial video , very informative .
Please contact : smile.mandy926@gmail.com.
The extension cord you took out of the package is a NEMA 5-15 115v single phase cord, not at all a 220v cord. If you plug that into a wall outlet in the US you will 115 volts.
That is correct. I should have mentioned that I'm using the neutral as another live where I am using L1 and L2. I appreciate this comment as I am pretty good with the digital electronics side but I am not strong in the electrician side. I make this clear on the spindle page as I have a disclaimer to seek a professional electrician for connecting a VFD. This disclaimer is here under the instructions section: www.buildyourcnc.com/item/spindle-inverter-2!2kw-spindle-vfd
So did you cut the plug off and install a 220v plug?
😮😮, wow, 😳😅, that's news to me too, I didn't know that. Now I know why I thought cable does not work 😂😂. M in Africa, 220V😊
Hi, can you share the user manual? Mine camed without it
The STU-300. Can you run the spindle full time with that? I ask because I got the 220v VFD and don't want to use it on my 220v outlet in my shop if I don't have too. Thanks
Since the Spindle is 2.2kw would an ST-3000 work be a better choice
Yes, you would definitely want the 3000 watt version if you are going to operate a 2.2kW (2200 Watt) spindle and VFD. Mind you that I have not tried this in production. We have a dedicated 220V outlet in our shop.
Thanks.
The manual that came with mine has totally wrong figures. This is a shit experience for me. Can you help me by posting what figures you used to code up your spindle?
thank your, one question, how i can move the spindle with the software? i have CNC usb controler but i cant move it
I could be wrong, but I believe most people do not control it that way. They turn it on manually, then run their cutting program. I've seen this done in many videos that way.
I installed my spindle like you showed. but instead mei u was connected to 1, v to 2 and w to 3 (the spindle supplier told me this). When I start the spindle with the button "run" it runs, but then all light (com, alm, dsp, run, hz, rpm) blink very fast and i cannot stop or adjust the rpms. Does anybody had the issue? Has it something to do that i dont have a break resistance or is just the wiring wrong?
❤what a majestic VIDEO!!THANK YOU 🙏 SO MUCH WHOEVER YOU ARE!! 1question 4 you: i have exactly the same VFD and I need to control the speed of an AC asynchronous Motor with raspberry pi; do you have any suggestion on the VFD wiring with the Raspberry pi? Could you please point me in the right direction? Thanks 🙏🙏🏿🙏🏿 a lot!
You only need the Rpi to output a PWM between 0-10V and use the VI and ACM terminals in the VFD with this PWM output. PWM to VI, RPi gnd to ACM. If you need a voltage reference of 10V, you can use the 10V terminal in the VFD.
@@PatrickHoodDaniel THANK YOU SO MUCH YOU ARE AWSOME!!! BLESS YOU
Have a question.. A Hz is frequency of output sinus, so it not exactly rpm?Need to divide by motor polys number for really rpm / rps ?Thank you
Yes. The given freq was its max modulation of 400 Hz to deliver that rated 24K RPM.
Do you have a video showing how to wire the breakout board to the VFD for Mach3 spindle speed control?
Yes, here you go: ua-cam.com/video/aD3_0NmUowk/v-deo.html
@@PatrickHoodDaniel Thank you!!
@@Jcreek201 You are welcome!

i also have a 2.2kw for cnc but its spinning CCW. The buttons or knobs on the inverter and the run buttons etc doesn't work on da inverter. It jst turns on n off from Mach3. No fwd/rve switch on it too. Can i chnage direction becz its meant 2 turn CW as shown on its motor description
Just swap two of the three wires that connect the spindle to the VFD.
Como configurar esse inversor?
Hello please. How do I fix the problem when my 2.2 best inverter is showing hoc
What type/ga wire do you use for the spindle?
I would recommend using 16 AWG, but 18 AWG has worked for me. Some spindles and VFD come with 18 AWG cable. The wattage is divided by the three phases, so the actual current on each wire is 3.333 amps.
Hello sir. please does anyone know how to fix hoc display problem in CNC Machine
Did you make a part 2 outlining the control wiring side by any chance?
Yes, this is one of them: ua-cam.com/video/0SLFuM4tzuU/v-deo.html
What spindle and VFD is this?
amigo compre el vfd Nowforever de 220v pero mi casa solo hay 110v entonces compre un transformador de 110v a 220v mi pregunta es como conecto la corriente si mi tranfo solo trae face-neutro-tierra y en las entrada de corriente del vfd trae R-S-E
Compraste un trifásico a la entrada y tú tienes monofasica
Mide el voltaje entre las terminales fase y neutro y si te da 220v conectarlas al vdf en terminal r y s una cada una
Podem me ajudar ele liga depois da erro 1 o manual nao chega muito específico aqui
How you manage to run the 2.2kw spindle with a 300w step up transformer?
I use a 3000W transformer for anything with load. The video here is only a 300W transformer because I am only testing the spindle and VFD with no load on the spindle.
You should definitely connect the spindle to ground, the forth pin needs to be connected to the spindle chassis. (Big mistake from the factory) And you should use shielded cable, with the shield connected to ground on the motor side.
Yes, we do. We recommend that the Protective Earth be connected to the housing of the spindle typically to one of the screws of the back round connector. Thanks for pointing this out.
I would connect the ground on the VFD end instead, unless the machine body has a better ground connection than the one in the mains cable.
Thank for the video. One other thing to point out (you will already be doing this if using shielded VFD cable) is that the green wire should never be used for a current carrying conductor (power wire).
I suppose, these don't require the home wiring to be three phase. Am I right?
Indeed - they generate three phases by converting incoming AC to DC and use PWM/IGBT's to generate an approximation of 3 phases.
What did you do about the ground in the spindle ?
Are you referring to the 4th pin at the back of the spindle?
yes :)
From the factory, that pin is not connected. Because it is a metal casing, we connect that pin (from the back of the connector, not the connector on the spindle) to PE (protective earth). I'm not sure if this is required which is why we require our customers to seek guidance from a professional electrician.
So I don't have to solder additional wire from the inside of the pin to the body of the spindle ?
I cant restore factory. Can you tell me?
was that a real head being blown apart?
I think it's from from an obscure 1981 sci-fi horror movie ua-cam.com/video/1qCszP4HI7U/v-deo.html, en.wikipedia.org/wiki/Scanners#Head_explosion_effect
I have Motor 37 kw
1780 rpm
220v
Can I use this Inverter
For the Motor?
This inverter is for a maximum of 2.2kW.
Hi Sir. Can you help please . Can Mach 3 programs to control spindle /VFD go forward and Reverse ? Thanks.
Yes. You can use the M3 to run forward and M4 to run reverse. M5 to stop both.
You will need to connect the VFD through two outputs on your controller.
Thank you very much Sir!
Hi Sir.
Do you have a video or instructions how to wire and pins set connected to control board ?
Thanks for your help!
hallo guys my spindle hot ... this is normal ?
I'm new to CNC, but it seems a VFD is not required, right? What can a VFD allow you to do with CNC that you couldn't otherwise do?
A VFD is required if you use a spindle. If you use a router, a VFD is not required.
@@PatrickHoodDaniel Oh, well, now it's starting to make more sense. I thought a spindle was just another term for a router that's made specifically for use with a CNC machine. Can you cool a spindle with air? I was looking at a 1050 FME-W DI spindle.
Actually, aren't these Kress/AMB spindles more like a router in the sense that they aren't water-cooled and don't need a VFD or am I wrong?
@@tomjoad6993 You can cool a spindle with air. There are air-cooled spindles, but I don't sell them. I like water-cooled spindles because there is no air movement pushing the dust and chips in the shop. Water-cooled spindles are great because it's less noisy (no blower fan) and the vacuum can work more efficiently removing all of the chips and dust. Water cooling is not a big deal to establish and it cal all be compactly fixed on the Z-axis.

@@tomjoad6993 I don't have very much experience with Kress or AMB. From what I know, Kress are very much like routers and don't need VFDs.

Why ground not connected to spindle ?
Add the ground.
Hi , why do you call it a spindle ?
The dictionary says a a spindle is 'a rod or pin serving as an axis that revolves or on which something revolves'.
The centre of an electric motor is a spindle but the whole motor is not.
I think you mean its an electric motor. Is the motor 3 Phase ?
He's referring to it as a CNC spindle. It's a term used in the CNC industry for the electric motor that drives the milling/cutting tool.
Same word, different context.
conduits inside of cable? Interesting...using cord for your spindle is no beuno. Spindle motor is three phase, plus you need a fourth wire out there for a ground. Should also be shielded. That VFD will make lots of interference which can drive your controls bonkers. Don't use 300V rated cord. Not safe.
And conduits are pipes that you run wires in as a raceway. Conductors are inside of cords.
Thanks for the expert advice. I currently use shielded cable and I add a 4th wire to the body of the spindle. Is that what you would recommend? What gauge would you recommend for 2.2kW spindle understanding that each wire would carry 1/3 of the current.
Great!
I would definitely recommend the protective earth connected to the body of the spindle motor. I think 16 ga would be the minimum size you'd want to use on a 2.2KW spindle. The 2.2KW motor will draw roughly 10 amps at full load, which is 10 amps on each wire, 10 amps total. You wouldn't divide 10 amps by 3 to get the current on each wire, or multiply 10 by 3 to get total amps. A three phase motor is sort of like 3 single phase circuits, only each circuit is 120 degrees out of phase with each other.
Also, I re-read my original comment and it looks a little abrasive. I apologize for that.
@@shampyswoodworking525 Thanks for the clarification. I was under the assumption that since the total drawn from the spindle was 10 amps (2200W/220V = 10A) and if the total current was traveling through three separate coils, that would be divided by three, making each wire requirement at 3.34 amps.
@@PatrickHoodDaniel no, that isn't the case. If you look at a 3 phase motor's nameplate, you'll see a bunch of ratings and data for that motor. One of the numbers will be labeled FLA, which is full load amperage. If the FLA rating is 10 amps, each leg will draw 10 amps when the motor is doing it's rated KW or horsepower worth of work. We would describe that as 10 amps, 240 volts, three phase. Likewise for a single phase 240 volt circuit in your house... same idea. Your dryer might have a 50 amp, two pole breaker feeding it. That breaker is essentially 2 single pole breakers tied together, each pole rated at 50 amps, not 2 poles at 25 each. So the motor's wire size needs to be sized to it's FLA rating, in this case a 2.2KW motor at the given voltage will be around 10 amps (A little less than 10 actually, because in the US the single phase voltage will really be 240V).
This is not how you should be wiring a VFD Drive to one of these spindles, Electrical Code would not allow you to do it like this, this is very dangerous to wire it like this
Can you point out the error?
But plugging it into the wall aren’t you feeding it 110v? Your accent sounds American
I use a step down convedrter that you don't see in the video. This converter accepts standard three prong plugs that appear like the ones used in 110V. I am American. I live in Florida.
Thats 110v not 220v WTF
Please elaborate.
Nah, it's a 240v, it is just wired up weird. He used a normal 120v plug, but when he plugged it into the transformer, it basically made the hot (black) the first 120v line, the neutral (white), the second 120v line, and the ground (green) the neutral. Building inspector would have their asses...
Lost me at calling wire conduit.
Very very bad end of this video brain blast
Shame on you 😡😡😡😡
This was from a movie released in 1981 called scanners.
it is unbelievably stupid of you running that with the collet and collet nut on it with no cutter in place .
Thanks for the comment, Tony. I typically take off the nut and collet when doing this. We know the dangers. Thanks for pointing this out so others know.
