A new VFD for the vintage lathe

[@RockingJOffroad]

Yes, when I saw the notification from KZbin, I was telling my Wife “ Finally my ears will be happy “ !

[@andyZ3500s]

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.

[@Rolingmetal]

It might make my videos a bit better :)

[@kymcopyriot9776]

What's left of my ears thanks you very sincerely! I run a very similar VFD on my old Hercus 260 lathe.

[@Rolingmetal]

I printed out a Hercus lathe operating manual, It was very good but hasn't helped a lot :)

[@Blackcountrysteam]

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 !

[@Rolingmetal]

Agreed that might help the motor from burning out.

[@infoanorexic]

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.'

[@Rolingmetal]

But now the unwanted critters might back.

[@lito11111940]

You're a good guy Rolling. Thumbs up for this video !

[@Rolingmetal]

That's probably open to discussion :)

[@hulmeag]

I have the same VFD on my Myford ML7. Works great

[@Rolingmetal]

So far it has also worked good on my vintage Karger lathe. (the blue one)

[@shaunwhiteley3544]

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.

[@Rolingmetal]

Some older motors don't do so well with a VFD, especially when the insulation is a bit wonky.

[@MaturePatriot]

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.

[@Rolingmetal]

It's probably a German made Herder knife.

[@crazyfeller5704]

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)

[@Rolingmetal]

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.

[@PSUQDPICHQIEIWC]

I didn't notice the resolution change, because I can't stream anything above 360p anyway.

[@Rolingmetal]

I guess we both need an upgrade.

[@CodyHunt-op5jt]

Do you know how to change it from 50 hz to 60hz I can’t seem to get the cursor to show up and move to change the hz.

[@pgs8597]

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

I'll miss the old Allan Bradley, was tunefull !

[@Rolingmetal]

I agree it had a certain EDM quality :) You given up on youtube?

[@Abbinc83]

Any idea how to setup the perimeters ? Mine keeps getting an over current fault err 1

[@cluideman]

If Slim Whitmans steel guitar hadn't worked in Mars attack that there Allen Bradley sure would have done the deed

[@ActiveAtom]

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.

[@Rolingmetal]

It has some worn tapered steel spindle journals with bronze bearings. But it's still usable bit.ly/2Z9kFUO

[@DavoShed]

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?

[@Rolingmetal]

No motor, just a box full with electrical bits. Most home used drives are 1 to 3ph but 3 to 3ph is also available

[@DavoShed]

Very interesting. So all that noise comes out of the electrical bits in that box. :)

[@Rolingmetal]

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.

[@DavoShed]

Very Interesting, Thanks for the explanation.

[@walrus68000]

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.

[@Rolingmetal]

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)

[@gangleweed]

@@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.

[@RasheedBarnes]

Video still looks good.

[@Rolingmetal]

It looked acceptable to me on a 24 inch full hd monitor.

[@benmarca2]

How is the VFD performing after 6 months?

[@Rolingmetal]

Zero complaints, and so far I have not been missing the lack of vector control.

[@PeterPetrakis]

The resolution looked fine

[@Rolingmetal]

It looked acceptable to me on a 24" full HD monitor. But most people these days stare a a pocket calculator.

[@MrArray1967]

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.

[@PSUQDPICHQIEIWC]

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.

[@Rolingmetal]

By default it is set to 10 kHerz and thats probably pretty high already. I doubt it will get much quieter.

[@johnstrange6799]

Nice. I like the wide shot at like two minutes in. It'd make a decent channel banner image.

[@Rolingmetal]

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!

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

[@EverettsWorkshop]

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 . . .

[@Rolingmetal]

I bit like that Renault F1 engine they made play some anthem. That would be cool. But I'm not really musically inclined.

[@zombieprinting2670]

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 :)

[@Rolingmetal]

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.

[@shaunwhiteley3544]

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

[@Rolingmetal]

Yeah I need to make that wiring a bit more permanent at some point. But we all know how that goes :)

[@stemer1149]

Very nice!

[@brosselot1]

is that 110v signal phase or 240V

[@Rolingmetal]

240 but it should work the same for 110.

[@lacaver64]

yes that is very very better and you have more torc

[@Rolingmetal]

Doesn't change the torque. But a vectoring drive might help a bit at slow speeds.
