    Ok here goes.!!

    Wiring first.!

    Take a wire from the DCM terminal on VFD and run thru the normally open (NO) contact of relay one(No1) on uniport and return to the FOR terminal on the VFD.

    VFD Setup:
    Set PD01 = 1
    PD02 = 0
    PD44 = 01
    The speed or frequency will need to be set manuely using the key pad.

    Mach setup.:
    Port & pins - output signals-output#1 = port 1 pin 16

    Spindle setup - relay control- untick check box
    Spindle setup - relay control- clockwise (M3) output# = 1
    Spindle setup - relay control- CCW (M4) output# = 2 (but wont be used)

    That should be it.? You may need to toggle the active high/low in output #1 if the relay turns on when it should be off.

    Then when mach see's M3 in the code it will turn the relay on which in turn lets the signal from DCM thru it's contacts to the FOR input starting the VFD untill the signal drops then it will turn off.? This will be done when Mach see M5 and turns the output off which in-turn shuts the relay off and signal drops to the VFD.

    Hope it works.? ( If it does then you need to thank AudioAndy not just me.!! . . . If it doesn't work then it's all Andy's fault. . Lmao)

    On holiday... hence I'm too late! Jazz has said what I would have suggested. Setting PD01 to 1 enables the external input...PD44 says which input.

    Hey Jazz, your "tutorial" worked perfectly!! Thanks a lot!!

    However I have a couple questions.

    The spindle is in the bed before it starts to spin. In other words it's the machine is doing the cycle and then the spindle comes to life - is the some sort of delay I could toggle with?

    Emergency stop - when I hit the E/Stop the machine stops and there is also a delay on the spindle shutting Down, but perfect when I hit stop in Mach3. Any ideas?
