    Have traced the 2 wires from the rocker switch to the vfd
    Red wire goes into vfd UX1
    Black wire goes into GND on vfd

    Oh. Interesting, and an unambitious design there. That means that the front panel VFD switch is essentially your Spin-Forward On/Off control. There's a couple of options to extend the use of that, however, the job at the moment is to get the spindle turning.

    Mach3 was set to use OUTPUT#1, but we now know that is irrelevant for the wiring that you describe.

    The above assumes that function parameter F001 is set to 1. (You've not confirmed this yet)

    So, you should know how to turn the spindle on/off.... albeit at zero speed. Can you confirm any visual difference on the VFD display with the VFD switch On and Off - I would expect the "Run" LED to illuminate when switch = On, and extinguish when "Off".


    Now, spindle speed control. This assumes F002 = 1, also. (You've not confirmed this yet)
    If you do confirm its set to 1, then changing to 3 should, according to the manual, give you speed control through the built-in pot. Try that and report back.

    If you want spindle speed control through Mach3 - I'm keen to know if you have a DMM and are comfortable using it. Simply - I'd rather see the behaviour of the board rather than the spindle (just removes a potential source of confusion). If I said that I'd like you to measure the output to the AI1 input, wrt ground, are you happy to do so?, and similarly from P12 to ground? (all references are to the VFD).

    Where I'm going with this is to verify that, for different spindle demands you can get an analogue voltage out of the board to the VFD. If that doesn't work then no amount of smacking the VFD is going to work. But I'd like you to confirm the above before I start writing an essay. Also, screen shot of Mach3 Pulley set-up window.

    Not sure if this is relevant or not.

    Looking at ports and pins outputs they appear to be on port 3 and everything else is on port 1

    Will do it now bud

    On the vfd we have changed the setting to F002 But nothing happens and on F001 the e stop came on on the vfd

    I'm reading this as, "On the VFD we've checked the setting of F002 and confirmed that this was set to 1. We've changed this from 1 to 3 and set this, but testing with the VFD switch ON, the potentiometer on the front panel still has no influence on the Spindle"

    and I do not understand "and on F001 the e stop came on the vfd" - There is no "e stop" indicator on the VFD, is there? You shouldn't change F001 (I don't believe I suggested that you should). The settings/values are taken from the manual thet I'd linked...
