As far as I can see from the ad the vfd is model AT1-2200X and the manufacturer part no/reference is Vikyehonmx4z17g. That is all I can get from the ad. I will apply to the family financial control officer and send in the order.

ND is 2 hours south of us. There is a receiving company just across the border that allows you to send something you buy in the US to them for cheap shipping. We then run down and pick it up ourselves. Better than paying the extortion prices for delvery by UPS or FedEx.

Many years ago our fearless leaders threw millions of tax dollars into developing the tar sands up north. Wanted to turn us into northern Sheiks. Look like geniuses now don't they. Tar sands oil actually went negative in price last week. No one wants that crap, it is hard to refine. Our dollar sank to $0.73 as a result. Too bad they didn't throw all that money into fuel cell development.

Thanks for the info. I would be interested in anything you can look up on the vfd.

DARN! Further research shows this to be a Huanyang VFD in disguise. I can't find a manual online. I would NOT buy this VFD.
Here is a guy that installed a smaller watt unit that looks the same:

The manual is too abreviated, so I assume it is not a vector drive. Nor has the ability to display spindle RPM on the LED readout. Question is has the vendor made enough improvements to trust spending money on this.
 
I have a pretty heft 3000 lb lathe with a 4000 rpm max, and I haven't needed to exceed 1500 for a good long while. I'd probably only do so with the collet chuck.

My Bridgeport VFD is from Automation Direct. It can show putative RPM as I have input a factor which is multiplied by the frequency. The factor was determined from the belt ratio. It's a GS2 and has the pop-out control panel that I mount on the mill. The VFD itself is in a NEMA box on the wall safe from pollution.

The VFD does not like low speeds with long runs. I need back gear for that. For a lathe a braking resistor would be a must-have IMO.

Hi
My Denford Viceroy lathe is fitted with an ABB industrial vfd. My other lathe is fitted with a Yaskawa V1000 3.8kW industrial vfd. The V1000 series is available in a wide range of power outputs.

I abide by my own advice. If you can, I recommend buying a Yaskawa or similar industrial vfd. The quality, performance and value for money is far ahead of cheap Chinese electronics. The UK seems to be the cheapest place to buy Yaskawa. USA prices are up to double.

I found a Yaskawa V1000 used on Ebay for a good price. But as Ignator said you have to watch the input voltage. On closer examination this one turned out to be 300-480 v input. There is a dizzying variety of cheap VFDs on Ebay and Amazon. All of them could ultimately be made by Huang for all we know. I am trying to use customer ratings and reviews to sort them out. This one seems about the best of the lot.

I guess you just have to pay your money and take your chances.
 
My friend Joco_NZ has an AT4 vfd on his mill and the manual shows that it has pretty basic features whereas I have a HY02 (Huanyang clone) vfd for my Bridgeport mill (yet to be fitted) which appears to be quite feature rich.

Whilst I have had mine running I can't comment on performance yet Joco seems quite happy with his.

What horsepower is your lathe? The unit from Automation direct is probably sized on the small size, a size or 2 bigger might work better,. My employer sells WEG so some of what I am saying comes from some of the training I have been through. Depending on use, light, Standard or Heavy duty - Light duty is running under light load and few starts/stops - in other words,when it runs it run for while and doesn't start stop more than a couple times an hour. Standard duty starts a moderate load and starts 5 times an hour, heavy load means it starts under full load with a large inertial load.
If you are going to start/stop more often it helps to go one size bigger on the VFD as has larger capacitors and can stop a slightly larger load. Some VFDs are fitter with the extra electronics to connect a braking resistor, which also has to be sized for the braking load. A larger Resistor dissipates more heat, and allows more stopping and more rapid stopping. The VFD reduces the current as the frequency goes down. Reduced Current means reduced torque. If your VFD has an option for Sensorless Vector Mode it may give better performance at lower speed, but anything less than 20 Hz may not be usable. You can change pulleys to lower the speed of the lathe, and you may be able to run the motor at a higher frequency, though there is some current reduction as the frequency goes over 60Hz. which will give you a wider usable speed range.
 
Hi

I went through a detailed selection process for my own application and ended up with a Yaskawa vfd for my latest retrofit. It is not the only good brand of industrial equipment but they are available in most countries.

I would steer away from used vfd's because the key components have a life expectancy. A used industrial unit is probably being replaced because it is near the end of life, or it is faulty.

If you download the Yaskawa V1000, you will find the part numbers for the different models. There are 13x single phase models with power ratings starting at 0.2kW. That many models makes it even harder to find a used vfd that matches your requirements.

Industrial vfd's are not plug and play. They have a vast range of parameters to set. Be prepared to study the manual in detail.

My lathe currently has a 1 hp motor. The three phase motor from Amazon is 1.5 hp and the vfd is 2.2 kw, about 3 hp rating. It all looks good on paper. Start and stop frequency is interesting. I suppose like most home lathes this one gets very light duty. You face the part, turn it to size, drill a hole in the end, ream the hole, thread a tap into it, part it off and call it a piston. Find out that it is too small for the cylinder because you misread the micrometer and do it all again. There is some starting and stoping in all that. Very light cuts however.

My small lathe has a 1HP motor. I leave the belts settings so a 60Hz motor would drive it at 390RPM per the existing chart. I do all sorts of tapping and die threading without ever changing over to back gear now with a Mitsubishi FR-E720-110-NA drive I got off eBay a few years ago. As I said in a previous post this replaced the Teco Flux Master 100. That old drive was NOT a vector type, not only would it cog at low speeds, but also stall out. I've done threading without backgear and could rotate the lathe spindle down to 3RPM with no stall. In tap and die sizes up to 7/16", but I know could go larger without using the back gear. I did just break a 8mm tap the other day, it was almost to the last thread, I had to put a bigger tap wrench on it part ways through. I'm blaming it on a dull tap, as I was doing mystery aluminum (could have been 2024 or 7075, and not 6061). My point is, it will develop high torque at very low spindle RPM for threading. And with the VFD set for max 120Hz operation, my spindle at this setting is over 750RPM. If I need faster, I can change the belts to exceed 2200 RPM.
On my vertical mill, a Wells-Index, I have a Hitachi SJ200. The belt setting on that are for 1300RPM when driven from a 60Hz powered motor. I was just using it with the VFD driving 300RPM to a 1 inch 2 flute endmill machining cast iron, that was very hard on a C-clamp that never had the foot where the clamp screw swivel meets up with flat, as it still had the casting pattern draft. So every time you clamped things, it would swing over at an angle. I fixed 14 clamps of 10 inch and 8 inch size last night. I was machining about .060 material off. It is so easy to dial in the spindle speed on these drives, as they both have the feature.
If you have to pay full price for a quality VFD, I would do that before buying an unknown drive, as in post #25 that Amazon link looks again like the same Huanyang design and not a vector design. Huanyang eBay auctions used to indicate they purchased the processors from Hitachi, as a puffing statement, which may be true, but probably 25 year old technology. Full price from a wholesale seller is maybe 2X to 2.5X of that cheap Huanyang drive. But when it out lasts you, and does what is needed, you'll be happy.
On a side story, I purchased a 1HP motor and drive from Dealers Electric ~25 years ago. This was a 1HP 3phase motor, inverter duty, and the Teco FM100 drive. The shaft on the motor was too large, so I removed the rotor, machined the shaft down to the metric diameter that fit my sheave Vbelt pulley. As this was for 2 vbelt diameters for the primary motor to jackshaft speed reduction. So after about 15 years, the shaft on the motor broke off. It was from vibration as the cast iron sheave was never concentric to the vbelt diameters. And when I did the shaft diameter reduction, I left a sharp inside edge on the shaft, as that is where it snapped off. At the time I didn't have a radius ground on the lathe bit. I've replaced that motor with a used one off eBay, and had to make a new mount for it, as it was a C-face mount motor, and had no foot base. My small lathe is a 10x24 Jet and 1HP is plenty. So part of the repair was making the sheave motor shaft to vbelt grooves concentric. I also changed over from rubber vbelts to the link style belts. Much quieter and smoother operation.

So ebay search with any drive of 220, 230, 240 selected, and only selecting known manufactures for 2HP I get the following search:
https://www.ebay.com/sch/i.html?_oa...ed%20Load=2%20HP&_from=R40&rt=nc&LH_PrefLoc=3I hope this link on your computer, and selecting Canadian item location produces an affordable drive. I could only sort on North American location.
The only down side, is if the seller does not properly indicate the voltage of the drive, you will never see the listing. If you can't find the full manual online before purchase, don't buy it. Also verify the full model number of the sellers listing to the manual, and validate it is the correct voltage input.
post edit: Also search for 3-10HP motors, there may be a deal available.
