    Oneway 2436 won't stay running..

    My 2436, runs, but after I stop it, it won't restart. I can get it to start if I turn the power off and wait a spell. It's worse with larger and heavier blanks for some reason. Help!! Thanks so much in advance.

    It sounds like something is overheating and a protection circuit is kicking in. Have you called Oneway?

    Any code displayed on variable speed drive controller when it won't restart?

    If you have the brake toggle switch set at short deceleration, with a very heavy blank, it will trip the VFD. If you change it to long deceleration, no problem. That's the way mine works, but it is a 1998 model.

    I think that Richard Coers has the answer.

    On some lathes with similar VFD controllers, they have a large braking resistor to absorb the electrical energy created by the motor as it is slowing down. But many do not have a braking resistor and you just need to slow down a bit more gradually.

    BTW, if you slowed down really quickly with a heavy piece, it might unscrew the chuck.
