I just picked up a 1993 Jet GH-1340T lathe but I can't find any real information about it. I'm hoping someone can point me towards a manual or electrical schematic. I'm going to power it up with a VFD but still want to use the foot brake most of the time. I thinking I can set the VFD to coast to stop when the brake is applied so I don't fight or harm the VFD. Not sure if I still want to use the forward and reverse contactors to break the motor leads or just use the contactors as inputs to the VFD. Anyone powering their lathe with a VFD and still use the foot brake? How did you set it up?

Thanks,
Randy

I traced out the wiring and drew up a schematic. Thinking I will use one of the main contactors to power up the VFD when I turn on the control selector switch. Have a basic idea of controls for the drive but won't be sure until the drive arrives so I can check out the manual. I still am looking for a manual. Any 1340 lathes that are close to this that has a manual I can get?

Thanks,
Randy
