    Updating the config now that I've got an external pot for speed control:

    P00.01 = 1, external start/stop
    P00.16 = 2, three wire motor control
    P00.17 = 5, X1 = jog forward
    P00.18 = 6, X2 = jog backward
    P03.12 = 5.5, analog input minimum frequency
    P03.13 = 60, analog input max frequency (the external pot was only pushing to 44Hz so upped this so that "full on" is now around 54Hz)
    P06.17 = 1, jog acceleration time
    P06.18 = 1, jog deceleration time
    P07.08 = 3, Analog input for frequency selection #1
    P07.16 = 8, jog forward frequency
    P07.17 = 8, jog reverse frequency
    P12.00 = 6.1, rated motor current
    P12.02 = 4, Motor pole count
    P12.19 = 10, PWM frequency (decrease audible noise)

    Connections:

    X1 = NO jog forward
    X2 = NO jog reverse
    X3 = NC stop
    X4 = open: forward, closed: reverse
    X5 = NO run
    5V --- External pot top
    AIN -- External pot wiper
    0V --- External pot bottom

    Switchbox wired up :D


    Tacho wired in for spindle speed.

    Run / Direction / Stop
    Jog Rev / Speed / Jog Fwd

    Now there's just the small matter of fitting it all together on the lathe :whistle:

    Edit: The run button is definitely green, even though the iPhone disagrees!

    Yours has more buttons than mine, and I think I’m about to be upset by the answer to this question: Jog forward / reverse, does what?

    Needz moar butonz!

    Jog is (kinda) instant forward and reverse - tapping either rotates the motor for as long as you hold the button down.
    You can (or should be able to!) control the jog accel/decel times so that it's faster startup and stop than the main "Run" command.

    Incoming vid....

    Here you go:



    You'll also notice that jog is a fixed speed. I've set mine to 7Hz but I'll see whether I need to alter that when I finally get it on the lathe.

    Hmmm. Mk2 maybe, it’s coming out in 5 years.

    Do you have a link for where you got the vfd?

    Sloooooooooooooowly getting this off the kitchen table and into the garage!

    Got some videos to edit, but this is a steel plate I've made up for the VFD and switch box.
    The white cable is the incoming supply - it's hanging loose now as it goes straight to the plug, but needs to get routed via the emergency stop button on the lathe, then I'll tack up the cable.

    The two armoured runs are 1) the 3-phase supply to the motor and 2) what will be the shielded cable to the sensor for the RPM-o-meter that's in the switch box

    3-phase going into the motor, which is mounted on my shiny homemade sled - you can just make out the 25mm diameter threaded bar that allows the sled to move up and down on its runners.
