Vfd Installed, Lathe Up & Running :)

Thanks for posting the details, Lonnie!

Very nicely done! Can you share additional information on the proximity sensor....manufacture, part number, perhaps reference to the spec sheet? I am getting ready to retrofit my lathe with a VFD (Sheldon lathe) and think the proximity switch would be an excellent feature to design in.

Mark was kind enough to send me the product list. He also installed a safety switch in case the proximity switch failed but I'm not sure where he sourced that from. Hopefully Mark can answer how everything was put together.

The proximity sensor - INDUC PROX 18mm SHIELDED PNP 8mm RNG 4-WIRE 10-30VDC N.O./N.C. 4-PIN M12 Q/D
Proximity sensor cable - CABLE M12 2m (6.5ft) Q/D 4-POLE RT-ANG FEMALE BLK PUR

Perfect! Thank you for the links!

I also have two-stage braking: 1 sec. is used for 900 rpm and below, 3 sec (maybe 4?) for above that. It takes a WHOLE bunch of energy to stop a 80 lb. chuck spinning at 2000+ rpm...

Yea... like maybe you might flip the lathe!!

I can see it now....Bill sets parameters up for that beast of a chuck for a 1 second stop from 2000 rpm..... the chuck stops, and the entire lathe starts rotating!!

Beautiful job!
Mark's control systems are superb . He makes a simple lathe into a "Smart Lathe". I grin ear to ear now when operating my Smart lathe. Mark is always helpful,patient and kind, a real gentleman.
Congratulations on your upgrades Lonnie.

Where can one find more information about Mark and his control system?

You can send me a pm (Contact button) if you need some direct assistance, I do post the designs and suggestions on line. But I can provide more specific information as needed.

That is a beautiful setup. The proximity stop alone is worth the price of admission, no more crashes when threading.

Hi
How do you wire the proximity stop,???
