- Replacing the 32 year old Allen Bradley VFD that has been running my old Lathe for a while, with a cheap little Chinese XYS-AT1 drive. Made possible by some donors with a fear of hearing loss :)
FYI: I am trying to make a some money for my youtube hobby through the Banggood affiliates program. Follow the link below, buy something you NEED, and I'll earn some commission. Doesn’t cost you anything extra and you're basically taking money out of Banggood's pockets and putting it in mine :)

What's left of my ears thanks you very sincerely! I run a very similar VFD on my old Hercus 260 lathe.
I printed out a Hercus lathe operating manual, It was very good but hasn't helped a lot :)
Yes, when I saw the notification from UA-cam, I was telling my Wife “ Finally my ears will be happy “ !
Just turned my computer on haven't even watched the video yet. Congratulations I know this has been on your want list for a while. Thanks to the people who made this possible.
It might make my videos a bit better :)
Nice drive regarding factory setting it's always a good move to set your motor current on the VFD helps if you get a stall etc !
Agreed that might help the motor from burning out.
Does the relay output work? I've set P51 to 20 but the relay doesn't actuate. I'm trying to wire up a start/stop circuit
You're a good guy Rolling. Thumbs up for this video !
That's probably open to discussion :)
Any idea how to setup the perimeters ? Mine keeps getting an over current fault err 1
Mine was set at 60hz by default and my table saw would not work unless I held in the power button. Once I changed it by turning the dial on the front to 50hz for 🇬🇧. The table saw switch worked correctly.
Some older motors don't do so well with a VFD, especially when the insulation is a bit wonky.
I have the same VFD on my Myford ML7. Works great
So far it has also worked good on my vintage Karger lathe. (the blue one)
What size motor are you driving with 1.5 Kw vfd? Do these drives only allow 1/2 the motor hp they are rated for? trying to match one up. Thanks bud :)
0.75 Kw (1hp) works fine. But some sort of protection against over heating would probably be advisable. I just check the motor temperature with my hands. Usually at slow speeds when running a bigger drill. No problem so far.
G’day RM, good to not hear your frequency drive, hope the new one performs well.
No I didn’t notice the video quality change but then I watch this on my smartphone.
Cheers
Peter
most views these days seem to come form smart-phones. And you really need full hd for a screen the size of a post stamp.
I got the same one a few months back. Not had much use but but has been working fine. My wiring is as bad as yours 😀 and as noisy. Cheers
Yeah I need to make that wiring a bit more permanent at some point. But we all know how that goes :)
Is the knife behind the box in the opening a 'German Eye'? It looks like one I had. Glad you could get you a new VFD.
It's probably a German made Herder knife.
Nice upgrade, while we too agree with you about retaining the old now replaced Allen Bradley. We sure like your lathe babbitt or olite bronze bearings either one are good your machine looks nice to us in black it is a true elegant girl.
Lance & Patrick.
It has some worn tapered steel spindle journals with bronze bearings. But it's still usable

I didn’t notice and resolution difference but you weren’t doing closeups of machine parts.
Love the new sound!
Do those vfd things have a motor inside them?
Did you say one phase going in and three phases coming out?
No motor, just a box full with electrical bits.
Most home used drives are 1 to 3ph but 3 to 3ph is also available
Very interesting. So all that noise comes out of the electrical bits in that box. :)
The actual noise comes from the motor. It acts as a kinda speaker for the carrier frequency of the vfd. The old vfd basically has a slow working computer that is in a better to hear audio range of the human ear.
Very Interesting, Thanks for the explanation.
You've thanked your donors.
I thank your donors.
Unseen things in the earth are probably thanking your donors...
I usually cut the volume way back. But if I wasn't quick and the volume was up, it made me want to put my fist through the screen. I should make that sound into a ringtone. For the most annoying person in my 'phone book.'
But now the unwanted critters might back.
hey man, love your videos
Well thank you sir.
Very nice!
Out of curiosity, regarding vat and whatever other fees your country charges. How many euros does a unit like that cost? If you prefer not to disclose, I understand. I can get one here in the states, off EBay, 1.5 kw, free shipping for $54.78, which is about 50 euro. Again, more of a curiosity regarding any additional fees than the actual cost.
I recently had to buy a few parts from amadeal in the UK. I don’t believe they charged me all the taxes they hit their own citizens with. Shipped to my home, it was just a few dollars more than the web price.
Thanks for sharing(even the noise from the AB VFD)
VAT (BTW) is 21% over here but you don't need to pay that if you package slips though customs :) Packages below 22 euro are exempt from import an VAT taxes. Up to about 100 euro you only pay some import taxes. Also over the shipping cost. Above 100 euro you get to pay import taxes and VAT. I believe I payed 60 euro including shipping. Might also have been dollars as I used paypal.
I didn't notice the resolution change, because I can't stream anything above 360p anyway.
I guess we both need an upgrade.
is that 110v signal phase or 240V
240 but it should work the same for 110.
How is the VFD performing after 6 months?
Zero complaints, and so far I have not been missing the lack of vector control.
Video still looks good.
It looked acceptable to me on a 24 inch full hd monitor.
I'll miss the old Allan Bradley, was tunefull !
I agree it had a certain EDM quality :)
You given up on youtube?
I have a cheap XSY-AT1 that looks very very similar. Easy to use but its running the motor very hot in a short time. I read its the carrier frequency but the chinglish instructions are no help and there's no online info. Hope you do better.
My motor on the blue lathe got rather hot when drilling at a slow speed. Cooling fan doesn't do much at slow speed. But as long as I'm careful and respect the limitations it should be fine (for a while)
@@RolingmetalI've just bought a 2.2Kw one of these on Amazon for approx. A$90. it's to go with a Deckel D bit grinder package that I want to sell, and as the grinder is 3 phase it will be more saleable with a single phase option too. BTW, your motors will run hot if you run them slow and load them up, they don't like slow running because when the speed drops the amps consumed by the motor will rise to compensate for the slow speed. It's a bit like running a car slowly up hill in top gear and using the accelerator pressed hard down to keep the speed up. I use one of these drives on my small lathe and I run the lathe with a 1:3 reduction belt drive so that when I want a slow speed the motor is still turning over a bit fast. That also keeps some air blowing through the motor. Another solution is to attach a 120mm pancake fan to the motor end so you'll always have a good air supply blowing through the motor at all speeds.
Nice. I like the wide shot at like two minutes in. It'd make a decent channel banner image.
Looked a bit dark after uploading. YT seems to make my videos darker. Not sure I might also be my computer. But playing it online, using a browser. It definitely looks darker the before the upload using a media player. It's driving me crazy!
@@Rolingmetal I like darker photos. More dramatic or something.
Lost of people like more contrast pictures but you loose a lot in details in the shadows.
@@Rolingmetal True.
Lol, you're hilarious! You could have recorded an "Old VFD Trio" with you and a couple buddies running the frequencies up and down on all three machines . . . granted, might have sounded like a horror movie soundtrack . . .
I bit like that Renault F1 engine they made play some anthem. That would be cool. But I'm not really musically inclined.
The resolution looked fine
It looked acceptable to me on a 24" full HD monitor. But most people these days stare a a pocket calculator.
If Slim Whitmans steel guitar hadn't worked in Mars attack that there Allen Bradley sure would have done the deed
Looks good I hope it’s lasts you along time, affiliated crap😁😁😁😁😁 I like that.
Alan.
I should probably read a marketing book someday, I think I kinda suck as a salesman :)
No more electronic fingernails on the chalkboard!!!
SWEET!
I can make you a compilation video. A best of....
@@Rolingmetal Donate that thing to the Hague. they can use it to torture terrorists with.
Noise torture? I really like the sound of vfd especially vvvf
My old Allen Bradley sound rather loud on camera. listen and enjoy :) ua-cam.com/video/dUXZ8C7U2AE/v-deo.html
I already start to miss this electrocuted chicken sound.
So you asking for some sort of "best of" video? That might make the EDM people happy :)
My ears thank you. ;)
Hopefully this one will last a bit longer. I should probably not dig around inside :)
yes that is very very better and you have more torc
Doesn't change the torque. But a vectoring drive might help a bit at slow speeds.
Dub in some local music over that screaming
I though people these days were into EDM.
Regarding the video resolution my answer is no. I didn't notice it was a lower resolution.
Regarding changing carrier frequency, I wouldn't do that.
Raising the carrier frequency will raise the power losses due to hysteresis - and
eddy current losses. Which implies heat dissipation will increase also.
That's one thing to consider, but those losses are going to occur in the motor. If it's limited thermal design that's a primary weakness in the cheap VFDs, it might simply be inadvisable due to the fact that raising Fc is going to increase switching losses and also reduce timing margins. I don't know how much I trust the design margins and questionable semiconductors to prevent delayed turn-off and catastrophic shoot-through in the switch bridge -- particularly if the thermal design allows them to run excessively hot.
By default it is set to 10 kHerz and thats probably pretty high already. I doubt it will get much quieter.

Yes I was just saying, "Even a halfwit like Rolingmetal can do it."
hahahahaha (you deserved that for that horrible sound of your old lathe)
No problem, I can accept that :)
@@Rolingmetal I was making fun of you calling yourself a halfwit. I actually consider you to be very intellegent...I mean ...obviously.
Im not donating shit , untill you take a hammer to all the A-B units...lol... Im sure you will bring them back from time to time , for your amusement ..kidding...
Sorry, but I probably need it again at some point :)
Your eyes are better and now your ears will stop bleeding, happy days.
Time to make some more videos
it looked the same definition to me. M
I don expect you would see the difference If you used a smart-phone screen
@@Rolingmetal it is a smart phone. M
glorifiedd pocket calculator!
11:12 Not cool!
Nope. And it's probably going to hurt :)
