Speed Controller Wiring Help

[saabman]

I have an IH electrical cabinet with internal VFD. When I got it the CNC4PC speed control board was backordered. I had Tommy mark all the wires (I thought). I now have the board and when I look at the marked wires I notice it does not have marked wires for ground and 12V. I would not be concerned if not for the warmings to be sure to have isolated ground and power.

So if you have a IH cabinet with internal VFD, can you take a look at the speed control board and see where the 12v and ground (power input) are coming from (a picture would be great)

Thanks, Chris

If that is the 12v I'm thinking of then it goes between the VFD and the control board. The vfd has a 12v pos & neg and they go to the board and this is the power that is fed back to the vfd for control. It is a straignt hookup. If you have the paper work on that vfd it should be noted. if not then give Tommy a call, he'll have it back at ya in 20 seconds or less.

5 wires go to the VFD, and they are all marked. What I am after is the 12volt power in to the board (and associated ground). Outputs are on the bottom, ctrl in on the left, and power in on the right.

I have a call in to Tommy. No doc on the VFD.

Reached Tommy and got the information I needed.
