    First have wired the spindle in Delta not Star.? The VFD is 380V so the Spindle needs to be wired Star.
    Edit: Strike that because looking again the other pic looks like from spindle not VFD.

    So are you using 1ph or 3ph input.? If 1ph then wire in Delta if 3ph then wire Star.

    Second measure the voltage coming for the speed control to VFD. Does it Pulse.? Will be either 0-5v or 0-10v depending on VFD/Speed controller.
    To check the VFD get power source between 1-10v (if 0-10v speed control) ie 9V battery and swap for wires coming from speed control. If you have stable speed then it's the speed control that's causing the pulsing.

    The Strange Mach3 happenings will be coinsidence because nothing related to the spindle can or will affect Softlimits. Only thing that could possibly be throwing unexplained errors is electrical noise and this would be on the hardwired limits not softlimits.
