    Ok well you have the Nvem S-axis wired up so were are you running those wires.?

    I've never used either of these but I've wired many others controllers and VFD's and they all pretty much work the same.
    Here's where I think they should go after looking at both manuals.

    S-axis /Gnd1 goes to terminal 5 on Vfd which is Analog Gdn
    S-axis/VSO goes to terminal 2 on VFD which is 0-10V.

    This is your 0-10V speed reference voltage. Terminal 10 on the VFD is a 10V speed reference voltage in case if you wanted to use a potentiometer (POT) and would go to the wiper of the POT. In this case you don't need it because the Nvem supplys the 0-10V

    S-axis/Out1 goes to STF on VFD (forward rotation)
    S-axis/Out2 goes to STR on VFD (Reverse rotation)

    Edited: After reading Nvem Manual little more.

    However this would mean you have to tie the VFD control logic Gnd which is Terminal PC on the VFD to the same supply Gnd that the Nvem uses.
    (this bit I'm not sure about now because I would have expected the Analog Gnd to be separate to the Output Gnd and it doesn't appear so reading the Nvem manual.?)

    You may be better and safer for the VFD using separate relays controlled by the Outputs to control the Run/Stop on the VFD by running the VFD connections thru it's contacts.

    All your basicly doing is using Outputs 1 & 2 on the Nvem to turn on/off the RUN signal on the VFD by shorting STF/STR to PC(Gnd).

    Then it's just a case of setting up the Outputs for Forward/Rev and Pulley speeds in Mach3 which the manual should tell you how.

    Hope this helps.
