    Default Servo amplifier/drive input wiring assistance please

    I'll try to keep it short.
    Looking at upgrading the spindle to a 1.5kw servo motor to control in mach3.
    Just need to know which inputs/outputs to use on the CN2 connection for: on/off, speed control, and if poss e-stop for if the spindle gets stuck so it stops Mach.

    The board I have is this one:

    Manual:

    I've found wiring for a different VFD drive:
    https://www.cnczone.com/forums/attac...d=391470&stc=1
    Video:

    Shows that on the board:
    The 2 connections for spindle on/off control goes top conn to FOR and bottom conn goes to DCM
    The 2 for the 0-10V spindle speed output goes top to VI and bottom to ACM
    Unsure if there is a stop circuit there.

    The servo I'm looking at is something like this:

    But the wiring for the CN2 inputs/outputs I have no idea on and have been searching a while so I thought you guys may be of assistance. The rest is fairly straightforward.
    Wiring diagram is like this:

    Thanks in advance.

    Default Re: Servo amplifier/drive input wiring assistance please

    O.k. guys/gals.
    A little update. I think I've found the manual for the driver type which is this one:
    https://www.fasttobuy.com//download/...anual_V3.0.pdf
    The wiring diagram for speed/torque mode is on page 20.

    Looks like the the speed/voltage regulation is + VREF & - AGND.
    Looking at the diagram and vid with the VI and ACM inputs previously I assume the line that went to ACM input from the BOB is the negative? Correct?

    Just need to know which to use for on/off and e-stop

    Thanks.
    Daz.
