Note that ALL A-B drives starting with 13.. are over 20 years old now and 100% obsolete. They can no longer be supported / repaired because the parts used to make or repair them are no longer available, which is why they are cheap on Fleabay and elsewhere. Buyer beware...We used an Allen Bradley 13xx on ours.
Common on Ebay for about $200.00 or so.
Go to the AB Web page and download a manual and you can see the application table that shows the models so you can get right one.
It has a table showing voltage, hp and phase input and required unit.
Most common are the higher voltage units but 240 volt models do show up.
We modified the drum switch to have one set of contacts "make" first and used it for the "stop" and the other 2 as "run" and "reverse".
Made frame that mounts to chip tray bolts under bed to support the box with vfd and added a foot bar for stop.
Looks factory with original drum switch control.
Added pot and main switch under bed.

What is your point sir?Note that ALL A-B drives starting with 13.. are over 20 years old now and 100% obsolete. They can no longer be supported / repaired because the parts used to make or repair them are no longer available, which is why they are cheap on Fleabay and elsewhere. Buyer beware...
Well... first, you tell them what you are going to tell them:What is your point sir?
Well... first, you tell them what you are going to tell them:
The capacitors a VFD depends on have finite lives. More than one mode of age and use related degradation.
Then you tell them:
The more reputable VFD makers even recommend the replacement point. Seven to nine years after it left the factory is not uncommon. Production date is usually ink-stamped on the basic label, post-production.
Then you tell them what you told them:
The caps NEED TO BE REPLACED. As recommended. "Re-forming" is not a bad move, but it is but a band-aid. It cannot, and DOES NOT, unwind the clocks, plural, entirely.
So.... WHEN, not IF, one moves to replace capacitors that a maker purchased by the thousands, tens, and hundreds of thousands at deeply volume-discounted prices, new ones that both meet the spec AND physically FIT, are nearly always more costly that a new VFD with the latest components - even technological improvements from lessons learned, their own field-failures, plus those of others in the industry.
New VFD of course, also contains NEW caps - all again bought at very high volume and deeply discounted competitive prices.
FWIW-not-much-dept. A brand-spanking new, and serious expensive 10 HP Phase-Perfect ALSO sez - right in the manual - that its capacitors are to be replaced periodically. At THREE YEAR intervals, to be precise. Not theory. I OWN the bugger!
No help for it. In POWER service, not as tiny signal-conditioning devices, AFFORDABLE capacitors are ephemeral components.
Perishable, IOW.
BFD, VFD.
So are most foodstuffs. We Just Deal With That.
You want a "thousand year old egg?" with your expected live-forever VFD?
Be aware they are commonly preserved with urea recovered from China's industrial scale animal husbandry operations. And weeks old, not millenia old.
Good news, actually, because the legendary longer-lived originals used lead compounds!
Old VFD can be full of unpleasant surprises, too.
Ok I'll specify a bit more. I'm wondering how to hook up a VFD. It needs to be a single phase in 120-220 and a 3 phase out 220-440. My motor is 1.5 horsepower and I'm looking for a VFD that handles 3 HP. So recommendation on a decent VFD would be helpful as well.
This is the one I'm looking at as of right now.

I second Tony's note on the 13xx. I made a cheat-sheet for programming and wiring, and while the concerns of capacitor age are correct, my experience has been that this concern has been overstated. All my drives are old, not a single one has capacitors that didn't appear in them the day they were made, and NONE of them have failed. They are, however, very ordinary capacitors, I purchased a set of replacements with the full intention of a destructive life test, but that point has yet to come.
