    looking at your photo of the terminals
    this is how I would connect to the VFD
    with the forward on/off control being BOB's the relay controlled by pin 17

    yes
    the relay switches the VFD on in the forward direction
    and is the simplest control with one switch
    depending on the parameters set for input X1


    you could have 3 switches
    one for on / off

    a second for forward that works in conjunction with the on /off switch

    the 3rd being reverse that works in conjunction with the on /off switch
