    Question Novusun EC500 Mach3 no Spindle output

    Hi,

    I am just retrofitting a lathe and am using a Novusun EC500 controller.
    https://www.nvcnc.net/ec500.html
    The output for pwm and also digital out 1 and 2 for cw and ccw won't have any signal.
    I configured it following the manual, but still without success.
    I also tried different setups different pins. No success.

    GNDS and VSO for the 0..10V input at the Vacon NXS drive
    com- and OT1 CW OT2 CCW

    Ports and pins
    Motor outputs
    Spindle enabled / StepPin 1 / DirPin 0 / Step LowActive / Step Port 1 Dir Port 0
    Spindle Setup
    CW Output 1 / CCW Out 2 / Use spindle outputs / PWM Control / Base 5 / Min 0 /
    Output Signals
    Out 1 enabled / Port 2 / Pin 1 / Active Low
    Out 2 enabled / Port 2 / Pin 2 / Active Low

    I can not measure any output at the connectors.

    Thanks for your help...

    Hi,
    if you go to the Mach Forum you'll be told that Novosun is on the blacklist because they peddle pirate Mach3 liceneses
    and you'll get no help.

    If you want support get a different controller like an Ethernet SmoothStepper or a UC300.

    No you can configure it for PWM output, you want to configure it for 0-10v not PWM

    I would say your problem is that your Ports and Pins in Mach3 don't match with the Novusun

    You can't use PWM output to control the VFD Drive although some VFD Drives can take a PWM signals most only have 0-10v as the main input for speed control

    Hi,
    I am having already one machine with the same Vacon Drive. PWM works perfectly on the 0..10V input.
    Unfortunately the manual is not very clear.
    I will try the pinsetup today again.
    Thanks
