Jet 1642 VFD is cold and dead

John K Jordan

As noted in the recent Powermatic VFD thread, the inverter on one of my Jet 1642 lathes has been flaky for years. After any short AC power disruption it would quit responding and report an error code but until today I could always get it to work.

We had some kind of power outage when I was gone last week on vacation and when I returned today the inverter appears completely dead - there is no display at all on the LED panel and no response from the reset or other buttons. It is getting AC power and even passing power to the lathe controls: the tach display on the lathe lights up and even changes as expected when the lathe is spun by hand. I did some basic debugging and the lathe controls are ok and nothing on the VFD circuit boards is visibly fried.

This is the 110v model of the Jet 1642; the inverter is a Delta model VFD007S11A, output 4.2 A, 1HP. I can't remember just when I bought it but it is probably 15 years old.

Fortunately the other 1642 is working fine so I don't have to drag out one of my mini lathes!

I'll try to call Jet tomorrow. Any suggestions are welcome.

John -

I sent a reply via email. Included a link to a suitable replacement inverter for $190 and instructions for wiring and programming. I'm not 100% sure on how the Jet 1642 is wired compared to a Powermatic, but it's probably very close.

Ralph, if I had your money I'd buy three so I could keep a spare in storage. :-)

I stopped in to see Frank Penta in Chapel Hill, NC Saturday and that scoundrel has two Oneways side by side - one with long bed extensions.

I hope you are doing well. I've been doing more carving lately (bradford pear) and thinking about you. I've also taken up chip carving and want to use it on some turnings.

I just got that email, thank you very much for your help. In looking at the photos on Doc Green's site the wiring on the Delta, at least, looks identical to the Powermatic. I also wrote down all the programming parameters in the Delta a couple of years ago so maybe that will help. The price is great - I'll give it a try and let you know how it works out.

Would you please send me the info as well?

Dick Coers

Curious what you get for that price. I'd like to get a bigger VFD for another lathe I have.

I purchased a VFD from Dealers Electric to upgrade a Southbend Heavy 10 to 3 phase.

I got the motor from someone else.

If I recall I got the Teco, JNEV-201-H1

The unit works well. A bit of a pain that input wire located at the top and output at the bottom.

If I did this again I would get the Teco, N3-201-CS-U since input and output wires are at the bottom and the display can be set at remote location.

For 115/230 volts it looks like they offer 1 hp for $190 and the one I ordered, 1.5/2 hp for $208.

For 230 v only they have a 3 hp version for $300.

Note that these are "open" design for convection cooling and must be protected from dust without limiting airflow. Their sealed VFDs are much more expensive.

I have a couple of thesehttp://www.automationdirect.com/adc/Shopping/Catalog/Drives/GS2_

that I use one for a drill press and one for a exhaust fan. They have fans to keep them cool so for they have withstood dust and shavings. I had the 1hp on a small lathe for a year before I upgrade to a large lathe and just converted my drill press over makes it a joy to use no more moving belts just turn the dial for the speed you need.

Those look great for smaller motors, especially on fed by 110v.

VFD replacement

Peter D'Attomo

I've had a GS-1 from Automation Direct for 3 years and no problems on a Oliver 159.

Cost at that time was 130.00

Both of the ones that I have are 220 one is a 1 hp and the other is a 2 hp Had them for a couple of years now without any issues. I bought one of their 1Hp motor to go on the drill press.
