Hey there All!!

I need a little help getting my computer to turn my mill off and on. I have a Teco FM50 VFD and a Logitrol controller that has 2 relays. I can hear the relay when I hit the toggle spindle button in Mach3 but cant seem to figure out how to get it to control the VFD. I have one wire out of my relay going to the FWD terminal and one going to the Relay terminal, and I also have adjusted the F10 parameter(Start/Stop Control) to 1 which is Terminal(TM2).

What am I missing folks? Any advice would be greatly appreciated!

Thanks in advance.

Normally with a VFD you will take a wire from a common supply terminal on the VFD and that will go to one of the switched contacts on your relay, the other side of the switched contact will then go back to the Fwd contact on your VFD.
