7i97 hookup help

Yes, idk if you suggested that the first time but someone on here did and I did just that with no luck. I have a 330ohm resistor on each of the inhibit wires to turnt he amps on and off. At first I had it hooked to 5v this way but then switched to 12v but with no luck. The amps still come on right when I turn everything on. I need them to be dead and then enable in linuxcnc

any spdt relay suggestions or a specific type I should be after

I would not expect that to work since you must ground the inhibit line to disable the drives.
This means the resistor must go from the inhibit input to ground. Then if you pull-up
the inhibit input with an enable or SSR output it should enable the drives.
 

When you pull up or pull something down does that depend on how its wired or do you think there is ajumper on the board to change this? Also when you say SSR you mean a seperate SSR right? Not something on the 7i97 board?

By pulldown resistor I mean an external resistor from the drives inhibit input
to ground. This should disable the drive unless the inhibit input is pulled up
by the enable output or SSR output.

You would need to measure the open circuit voltage (no pulldown resistor)
on the inhibit input to determine the required pullup voltage.

Connections:

V+ --> SSR+
SSR- --> drive inhibit input
Resistor_pin1 --> drive inhibit input
Resisior_pin2 --> drive ground

V+ determined by open circuit inhibit voltage

By SSR I mean one of the 7I97s 6 built in SSRs

Is any of this looking right so far? Some guidence would be appreciated
