Thanks. That certainly keeps the VFD from fighting the motor while braking. I used the brake switch to remove the enable input to the...

Selector switches, such as a HAND-OFF-AUTO switch, can be drawn this way, to indicate which contact closes with which switch position...

Yes, pin 7 is closed in the off position. I got lazy in my drawing. The named contacts close when the carriage lever switch is in that...

Thanks for the info. This is the drawing I made of the original wiring. I followed the link and the Jet lathe pictured looks like mine...

Latest update. I changed quite a bit of wiring but I have the lathe working as I want it to. When I step on the brake the drive enable...

I bought a DURApulse GS10 series drive from AutomationDirect. The 3HP drive is about $200 w/ free shipping. Found it mentioned on a...

Thanks for the info. The VFD I bought has an auto accell/decel setting that's supposed to sense the motor current and give the best...

My lathe didn't come with a coolant pump. It's prewired for a 3 phase one though. I have a stand alone coolant pump that's 120V that I...

You DO NOT want any contactor between the VFD and motor. It's the quickest way to blow up a VFD. So never put a switch contact between...

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...

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...

Thanks for the reply and the extra information. I'm asking for future needs if it comes to it. Randy
