    Default Setting up Spindle/VFD control Issues 6040T

    Hey all.

    Mach4 4.2.0.3804
    ESS Build 232
    Gecko G540
    Nowforever VFD

    Ive been using the setup for awhile with just the Potentiometer on the VFD for spindle control, I want to setup software control with the ESS/Gecko/Mach4

    Ive set it all up as I believe it should be (following manuals etc) but as soon as I connect the wiring from the GeckoG540 to the VFD it activates the spindle and sets it at 232hz no matter what I change?

    My wiring is as follows:
    Gecko G540 Pin 7 (VFD Ground) --> Comm Terminal on VFD
    Gecko G540 Pin 8 (VFD Out) --> X1 Terminal on VFD (Spindle FWD Input)
    Gecko G540 Pin 9 (VFD 10V) --> AIN1 (Analog Input 1)

    Software setup:

    Mach 4 ESS plugin config:

    Spindle: Type = PWM
    Frequency Hz = 400z (im not actually sure about this one? how do you know the base hz, I just choose the max hz

    Pins Config:
    Port 1 - Pin8 - Out - Active High - Spindle PWM
    Port 1 - Pin9 - Out - Active High - Spindle FWD
    Output Signals:
    Spindle Motor PWM - Enabled - Mach Mapping ESS Only - Pin1 Mapping "Spindle PWM"
    Spindle FWD - Enabled - Mach Mapping ESS - Pin1 Mapping "Spindle FWD"

    Mach 4 Config:
    Output Signals:
    Spindle FWD - Enabled - Device = ESS - Output Name Spindle FWD

    Ive tried setting different pins, setting active low, changing spindle FWD to Spindle ON, even swapped the wires on the VFD (x1 and AIN1)

    Oh I should mentioned Ive changed all the setup parameters on the VFD to suit analog control through AIN1.

    But yea no matter what I try it just turns the spindle on straight away at 200odd hz

    Im out of ideas.

    As for the Hz setting I think there is a number that is recommended of 32Khz for the ESS and PWM 50

    Do you have a 10v supplied to the G540

    First you have to check to see if you have up to 10v coming out of the G540 if your spindle is 24,000=10v 12,000=5v you use these speed numbers in MDI to test the output M3S12000=5v out you have to get this part working before anything will happen
