KMG pics and video!!

Ok, Pad. Here you go.

Here's a repost of the wiring diagram for my VFD (TECO FM50, 2hp):

Here's the clean box with the VFD wired up:

And here's the control box with the speed pot and fwd/stop/reverse switch:

By matching colors, it should be pretty easy to tell where everything goes. The green wires coming in from the Line-In is a true ground (not a neutral...it's capped off), and the green coming in from the motor side is the motor chasis ground. They are connected to a grounding strap that was provided by the VFD manufacturer.

If you have any questions, please let me know.

Thanks Nathan, that is very clear. The only thing left I have to figure is where to wire my emergency mushroom stop in this.

I really appreciate your help and the time you are taking.

Well, I cant take credit for the box. I got that idea from a fellow members post a while back. It works well, though. No dust inside.

Pad, as for the emergency stop on this VFD, it wires in to the same 12V switch lead as the fwd/rev/stop switch, and the return goes to a programable input that can be set for emergency stop (SP1, I think...I don't have the manual here). There are functions within this VFD that can be set to control the behavior after the emergency stop is triggered. It will be a bit different, depending on your brand vfd. Post up the terminal diagram and we can help you out.

Nathan, I got the same VFD as you.

On a side note, I opened the motors wiring box. Talk about a rainbow of colors. :eek: Good thing I have a diagram on them. I think I have wiring diagram from a post here a while back.

Thanks again.

Glad it helped you out! I have since added a 3/4 hp disc grinder and a 2 hp GIB 2x72" grinder being controlled by the same VFD. I built a switch box to switch the output between motors with one speed pot/fwd/rev control. Here's a pic:

They are NKK high capacity 3-pole dual toggle switches. They're rated for 30 amps to cover any load my motor would place on the switch.

I bought them from Mouser Electronics (part number 633-S832-RO)
