Wiring a TECO L510 VFD to Run My 82 Year Old Milling Machine

In this video I go through the wiring connections used to power a Variable Frequency Drive through an AC contactor with a circuit breaker and an inline fuse. This will be used to run my 82 year old Bridgeport milling machine.

For the cables I unfortunately don't have any good links. The 4 conductor shielded cable that I used was purchased a long time ago at Home Depot but they don't seem to carry it locally anymore. The writing on it is - SOUTHWIRE E163891 18AWG 4C SHLD CL3R. Home Depot sells it by the 500' roll as "Security Wire" but it's pretty expensive. The 7 conductor wire that I used to hook the low voltage controls to the VFD was purchased by the foot locally at Home Depot sold as "Sprinkler Wire". It might not be the best option but it's what I was able to find on short notice. My guess would be to search around for "Security Wire" and I believe that CL3R will be the code to search by for the 3 conductor. Not sure about 7 or 9 conductor shielded cable.
The power cable from the wall outlet to the contactor is 14 gauge 3 conductor 300V wire and was purchased locally by the foot at Home Depot. They used to carry 14 gauge 4 conductor wire by the foot but I haven't been able to find it so I had my electrician friend get me some from a supply house. Your availability may vary by location.

Just amazing skills and willingness to give others the opportunity to learn. Thank you!!

[@stevem268]

i just found your channel and clough42. great resources! i am repowering my 1940's wood lathe with its 12 speed belt drive to a vfd, same vfd actually

[@billgilbride7972]

So helpful! Well produced! Spot on with all that needed to be said! Thank you!!! I look forward to using this for my lathe.

[@LucidAutowerks]

Glad it was helpful!

[@tr6scott]

Looks good, most vfd manufactures would want you to scrape the enclosure paint on the ground lug.

[@LucidAutowerks]

That’s a really good idea and something that I overlooked.

[@Connorkmiec93]

This is tremendously helpful, thank you! Cpuld you please help me understand how to adapt this for a 220V supply? Can the same contactor be used, simplty swapping the L2 with the neutral?

[@DK-vx1zc]

most helpful, thanks for sharing!

Thank you so much for your thorough explanation! Great job! Subscribed

[@WilliamGrinley]

I've been looking for this very thing. So glad you took the time to go thru how you did it. I've seen Clough 42's video and most of it's over my head- you made it simple to follow. I have a step pulley mill and still want a pot to change speeds within the steps. Plus, my rotary switch is more than 30 yrs old-it's got HiForward, LoForward and the same for reverse. I don't like the switch and want my VFD to control it all. Sound like a good candidate for the setup you made? Thank you again for explaining it all and including your parts list!

[@laneburgess1643]

Good job.

Nice video--the wiring diagrams are incredibly helpful. Anyone wire this setup with a L510-201? I'm trying to figure out what contactor to use and how to wire the remote controls for a 220v input. I initially used a Fuji Electric SC-E1 contactor but can't get the normally open start switch to activate the coil.

[@WilliamGrinley]

For the switch, did you buy the 8 terminal 20A? What determines the number of terminals you need?

[@garbo8962]

Know its stupid but 99% of machines that have a forward, off, reverse selector switch for some unknown reason forward was always on the right side. Best to have every selector switch operate the same. Only used a green wire to designate that its a ground wire.

[@bucknakedracing68]

Do you have any insight as to why my contacter gets hot and smokes after 5 minutes? I’ve rechecked my wiring and the vfd seems to work fine. The contacter will eventually get too hot and pop and my second one is doing it too. I’ve ordered everything from your provided links. Could it be poor quality parts?

[@LucidAutowerks]

Not sure but sometimes heat is caused by resistance which is caused by bad connections. I’d start by making sure that all of the wires are appropriately sized and all of the screw terminals are nice and tight.

[@bucknakedracing68]

Which gauge wire did you use for hot and neutral wires at the contacter? Aside from that detail I’ve ordered every product you had linked and found the 18ga security shielded wire.

[@renearellano3907]

What kind and size screws did you use to attach components to box? TIA 9:58 9:58

[@LucidAutowerks]

They were small pan head allen screws that I purchased at Ace Hardware. I forget the size of them, though.

[@renearellano3907]

@@LucidAutowerks thank you for your prompt response! Did you have to tap each hole then?

[@jimcollins9316]

Is this 110 or 220 volt input?

[@LucidAutowerks]

110v input
