    Sunfar e300 wiring?

    Just picked up a axbb-e board http://libraries.sharpsoft.com.au/ma...manual_web.pdf

    I have everything working but can not figure out how to connect a sunfar e300 inverter to it (the pins are different to what the show in the abxx-e manual).

    Manual says to connect

    board-Inverter
    O2 - s1
    O3 - s2
    24v0 - sc
    AO! - A1
    5v0 - AC



    My inverter ports are

    TA
    TB
    X1
    X2
    X3
    OC
    CM
    FWD
    AI
    10V
    24V
    AO

    any help/point in the right direction would be greatly appreciated

    O2 -> X1
    O3 -> X2
    24V0 -> CM
    AO1 -> AI
    5V0 -> CM

    Your inverter uses the same CM pin for Analog Common (referred to as "AC" in the AXBB manual) and Digital Common ("SC"). Some inverters have separate pins for those.

    That got it turning on and off. Can control the speed from the inverter but no control from Mach3.

    When I turn it on in the software it says “Pmw bumped to minimum settings”

    My ports and pins config are

    Can live without it though.

    Thanks heaps for that appreciate it

    If you are still able to control the speed from the VFD Drive then you don't have the VFD Drive programed correct for remote control

    The Base PWM should be either 50 or 100 for it to work correct minimum % can be 0

    You also can't use spindle feed back unless your spindle has an encoder or a speed sensor in place

    The screens broken and she’s pretty rough, it’s a old machine I picked up awhile go, I mite just replace it - anything you would you recommend?

    Only got around to actually useing the machine - spindle spins anticlockwise.. which wire / setting would I change to make it spin clockwise?

    As a quick fix I’ve just been jumping the fwd and cm pins on the inverter if that info is if any use.

    Check your spindle plug

    Pin 1=U
    Pin 2=V
    Pin 3=W

    Pin 4=Gnd

    This is the normal wiring to make the spindle run the correct way

    I don't see a direction change Parameter, so if you have it wired correct then you can change an wire U V W but first check the spindle plug pins to the U V W on the VFD connection

    It is not safe to jumper the FWD and CM they have to be switched by your control
