I did search the web, this section and the rest of the forum, but I can't find an answer to this. And I'm not an electronics guy, so please keep it simple.

I got an Emerson Control Techniques Commander SKB1100075 VFD (not hooked up at all yet) that I'd like to hook up to the G540 and control it through Mach3 once I know it's functioning properly using the keypad on the VFD.

But here's the part I am having trouble with, it's the wire(s) hookup from the G540 to the VFD because they are marked different on both units.
The G540 manual shows terminals #7 = Ground, #8 = Output, #9 = +10VDC are for the VFD.
The VFD terminals (I think I'm looking at the right ones) are T1 = 0V, T2 = Remote Current Speed Input, T3 = +10V Output, T4 = Local Voltage Speed Input. There's a B1 = Analog Output Motor Speed (but I think this is for a read out, tachometer), everything else on the B strip is Digital or 24V, so I don't know if I need any of the B terminals for this?

The only one that looks right is #9 goes to T3, since they are both marked +10V.
Does #8 = Output go to T1 = 0V?
And what about #7 (ground), does that actually go to a ground terminal on the VFD or to one of the T terminals, and which one?

Any help would be appreciated
