I bought a Teco JNEV-203 H1 VFD.
I hooked it up and programmed all of the settings manually, and it runs my spindle very well.
Now, I am trying to get Mach 3 to operate the spindle through my PMDX 107 card.
The 107 card is a daughter card that mounts piggy back on the PMDX 126 Breakout board. It is for spindle operation.
Here is a wiring diagram of how I have it wired:

This is the screen-shot of the MACH3 spindle page:

It is probably something set wrong. I went through the programming of the vfd. It is really neat all of the different settings you can do.
After trying the different on/off/fwd/rev stuff, I quit before damaging something.
Does this need a relay to turn the spindle on/off & then the PMDX board just tells it which direction?
Thanks for all of the help,
