I wish I had watched your VFD videos first. You keep it simple and easy. Thank you!

[@xyloeye]

Thanks, Steve. The brief Chinese manual was making me crazy. Great explanation.

[@derekwilkinson7939]

Your recommendation prompted me to buy the XSY-AT1 inverter and the 1HP TEC motor. I couldn’t be more pleased it’s so quiet and smooth running it’s fantastic. The external control panel is going to be my next job. Great video Steve. Cheers. 👍. I’ll just add that this is on my Myford ML7.

[@allanwoodward6117]

Many thanks for sharing once again Steve, I managed to get my pendant control sorted after spending some considerable time digesting the wiring and programming book. its brill to see your video as its confirmed I've wired mine correctly also.

[@markkrick8602]

Well well done thank you!

[@GW-kl8jx]

Great video as allways

[@SteveJordan]

Hi, Thanks for watching and for your encouraging comments. Regards Steve

[@simonkrezias7615]

Very clear presentation as usual.Keep up the good work.Thanks for the video

[@44Celt]

Spot on Steve, got the same inverter and been wanting to do this, many thanks

[@bas63bb47]

Great exhaustive explanation! Many thanks for sharing your experience, it's priceless!

[@elchuco00]

OUTSTANDING VIDEO!! Thank you!!

[@MrPatdeeee]

Absolutely Brilliant!

[@brunomtn]

Tanks very much...best regards from Portugal

[@steph2211]

Very nice Steve a well done job.

[@carlosmartins3664]

Muito bom video com explicação em linguagem simples mas exaustiva ao pormenor. Parabéns. Estou ligando o vfd AT1 ao meu mini torno, e a parte dos comandos exteriores parecia complicado mas agora já não. Obrigado e cumprimentos de Portugal.

Greart....👍👍👍

[@Blackcountrysteam]

Informative video Steve but I would have liked to have seen a 'raised' stop button either replacing the flush one or as a additional E/S

[@SteveJordan]

Thanks....The off switch is raised somewhat in use and is very sensitive, but I was going to fit an additional mushroom type E/S soon and one or two other things, just for good measure. Just waiting for some components to arrive. Regards Steve

[@mikewilliams-mj9rd]

Hi Steve...Thanks for this video, I have the same VFD on my mill and did not know how to put on switches and to program VFD....Thanks agine.

[@geetee50]

The on off ticket maybe a little over engineered 😉. great post, any ideas what may cause the rotation to stop but run again after resetting safety stops, this can happen under load or running low revs with very light cuts after 30mins ish.

[@dano5143]

Thank you. This is a big help.

[@robertsild548]

Thank you. Great video. Now I know much more. I have same inverter and manual is without parameter explanation.

[@stephentayler1414]

Hi Steve. Thanks for this video which is great timing for me. I am just putting my lathe back together having just changed the head-stock bearings for FAG angular contact bearings and replacing the plastic gears with metal ones. I didn't find anything actually wrong in the head-stock. Though I suspected a broken gear ,as it was so noisy, particularly in low gear. The plastic gears were pretty loose on the shafts and there was absolutely no lubricant whatsoever in the head-stock. I know in theory nylon gears do not need lubricant and nor do the sealed bearings, But I would have thought the selector fork assembly would have some grease on it. One of the original bearings they had painted over and it felt a bit crunchy, though the other bearing seems OK. I also drilled and tapped the holes in the head-stock that you showed in an earlier video for oiling the metal gears and of course replaced the grub screws on the change fork and lever. I should have the lathe all back together today. I have always intended to go the VFD 3 phase motor route with the lathe eventually, but there was little point doing it with the little clarke lathe that only uses 3" chucks, so decided to wait till I got my cj18a from amadeal. Been a bit to cold in the shed lately though so much has taken a back seat in my little workshop, looking forward to some warmer weather in the not to distant future. I always enjoy your videos Steve, I must admit to preferring your workshop projects to the product reviews. Though the reviews you do are are excellent also. Keep up the good work Steve.

[@SteveJordan]

Hi Stephen, It is always interesting when taking these lathes apart to see what one will find. You sound like you just get on with the job like I do when working on the mini lathe. I have found it too cold to go out in the workshop lately. I have been doing a few extra reviews lately whilst waiting for some warm weather. I have several machining and 'things to make' projects lined up, when it does warm up, which will be much more interesting. I actually like doing the machining and making videos best of all, so getting my lathe finished is a great start for the year. Regards Steve

[@stephentayler1414]

Yes you have done well there Steve, great upgrade, I love it when a plan comes together. Did you know you can get a rubber grommet for the bottom of the control box where the feed screw goes through the box and that seems to keep out most of the swarf? Arc eurotrade sell those, (Arc Eurotrade are relatively local to me and they are always pretty helpful) they are quite cheap. Well the cj18a lives to tell the tale. I expected a bit of clatter from the metal gears, but mainly that is down to the change fork between the gears.However It is much quieter than it was. and the noises I can hear no longer worry me, as I know where they are coming from. Best Wishes Steve.

[@barbaraheitz7591]

Does the vfd still display still the speed display when wired this way? Thanks very informative.

[@SteveJordan]

The display stays the same when wired this way. Regards Steve

[@jean-claudegolovine5725]

very interesting. Thank you!

[@brunomtn]

Excelent video, big big help...it is possible feed the tachometer with the 5V?

[@joeygonzo]

gold!

[@berkotropia]

🤔I had been hesitating for a while about the type of VFD to purchase. After watching your video, I ordered a 1.5kW version. I am building a pendant just to play with the VFD auxiliaries. You made a great job! Anyway, what parameter did you change for the FWD/REV button? It's missing from the video! Please advise!😑

[@alt-w7130]

Great project, how you hooked up the the tachometer to the machine??

[@muzzicman03]

Hi I have a post drill and brought 1 of these on off chinese switches with the numbers 11 21 31 on one side and 12 22 32 on the other how do I know what is live and what is neutral by the numbers I have live and neutral in and live and neutral out on the old switch I need to replace thanks jon

[@gerritwinters2242]

Oke, thanks

[@mikewilliams-mj9rd]

Great job, thanks for showing this. one question about the com. block do all the black and yellow wires attach to each other ? Thank You.

[@SteveJordan]

Hi Thanks. Yes they all connect to each other.

[@iwanagodny7619]

Witam!!! Czy ten falownik ma sterowanie RS485? Jeśli tak to gdzie podłączyć przewody? Dziękuję i pozdrawiam!!!

[@tailgunner2]

Does this thing work with single phase American 208 volt input?

[@BillyTpower]

what do think about the uni-directional link belt you are using? will that be a problem running backward? Why or why not?

[@SteveJordan]

Hi Billy it works both ways without any problems. I have one on the Myford Lathe as well. It shows no difference in performance either way. Regards Steve

[@44Celt]

Are the on/off switches latching or momentary?

[@SteveJordan]

They are latching switches

[@jbrawo9732]

Hello, I have a problem with the same inverter, namely after connecting according to the instructions and starting the motor starts to vibrate, do you know what could be the reason

[@michaellinahan7740]

Steve, On the last shot of the control box it states that it is a 3 phase controller but in the description it states single phase Which is correct?I have a similar lathe and have been thinking about a suitable vfd / motor combination. What is the low rpm torque like? Mike

[@SteveJordan]

Hi Michael It is a 220v AC Single phase input to 220v Three phase output VFD. I find the low torque with my 1HP motor to be excellent and can use large drills. I have the same VFD and motor set-up on my Myford ML7 lathe, although on the Myford the VFD box housing is a different shape and color, with the same electronics.

[@michaellinahan7740]

​@@SteveJordan Thanks for the prompt reply.

[@gerritwinters2242]

Hello, in the video i see that your motor has 4 wire,s that you connect to the vfd, mine has 5 wires: green/yellow and 2 black one,s and red and bleu can you tell me witch wires i have to connect to the vfd ? it is an induction motor single phase thanks in advance Gerrit

[@SteveJordan]

Hi if it is the same VFD that I have you can't connect a single phase motor to it. You need a 3 phase motor. My VFD is single phase input. Three phase output.

[@BritishLifeSafetySystems]

How has the VFD performed? How good are they?

[@SteveJordan]

They seem to be very good. I have one on each lathe and don't have any problems with them.

[@andreout6920]

halo mr jordan my name is andre i follow you on you tube very educational videos i did the same with my mini lathe c2 if it cost you my 2 circuit boards so now also have 3phase motor and vfd exat the same as you also exakr the same unfortunately the potentiometer reacts differently at 10 = 0 and 0 = 10. and the forwards and backwards on the vfd give the opposite of i have connected it exactly as on your movie i hope you can help my thanks in advance. best regards from Holland from andre out.

[@berkotropia]

To change the operation mode of the potmeter, just simply swap the wires of the COM and 10V/5V.😊 The same to do with the FWD/REV button.

[@himars5410]

how i can change overcurrent i need 3.7a

[@douglangdon6810]

This servo motor from Banggood should brake as well as drive. 220V 400W Energy Saving Mute Brushless Servo Motor for Industrial Sewing Machine.

[@terrygriss4132]

They do a 550w version as well

[@himars5410]

hi is posible to set 50hz and all time keep same just use on off externall switch

[@SteveJordan]

Hi Yes there is a parameter setting that for this. All the program parameters are still programmable using the VFD keypad after setting up the external control box.

[@karllaun2427]

Do you have a link to the on/off switches? Thanks!

[@ProfesionalNewbie]

This video has been extremely helpful for me. There's not much info out on this VFD. Thank you. Could you tell me how to program separate momentary switches to control Run and STOP?

[@SteveJordan]

Hi if you watch my video "making and wiring a mini lathe vfd control box you will see how to wire it and alter the vfd setting. Regards Steve

[@ProfesionalNewbie]

@@SteveJordan Thank you for the reply. In your video, you use a latching or toggle type switch, I was wondering if you knew how to use 2 separate momentary type switches, one for Run and one for Stop. Upon further searching, I'm kind of thinking that this VFD can not use momentary switches to do this. Thanks, Jim

[@aguycalledlucas]

@@ProfesionalNewbie did you ever figure this out? I’m trying to do the same?

[@ProfesionalNewbie]

@@aguycalledlucas Not really. I ended up using a latching switch that ,when pressed and latched, would run and when released would stop. I also put in a E-Stop button.

[@thebeststooge]

I thought the Chinese lathes already come with a forward/reverse/variable speed control so why this?

[@SteveJordan]

I have converted mine to a much better motor and electronics.... ie 1HP 3 phase and a VFD.

[@thebeststooge]

Ahhhh, I was wondering why.
