    UB1 Analog Output Setup

    Hi Guys, , I'm really hoping you can help me as I'm struggling with this pwm spindle control ????
    I have an eth300 with ub1 board. So far I'm really happy but can't seem to get my spindle control working correctly.
    I have connected a 10v supply to the AH1 from my VFD. I've metered it and can confirm it's 10v.
    I've then got GND from the VFD to AL1 on the Ub1.
    AO1 is wired into the AI1 on my VFD.
    FWD signal wired in correctly and works.
    On the software I have PWM pin 1 and Port 4 as per the manual.
    I've set the Analog channel to 0 and 1 and it makes no difference.
    All solder bridges are as default.
    My max spindle velocity is set to 24000k
    If I send s24000 via the mdi and ramp the slider to 100% I only see 7.5v on the Meter from AO1.
    I would of expected this to be close to 10v if I understand this correctly?
    Any help would be a huge help.
    Many thanks
    Paul

    Check PWM=300 and the spindle Pulley setup

    Thanks as always Mactec.

    I'm not sure I'm understanding what you mean. Which setting gets changed to 300 sorry?

    The PWM settings in the control Spindles settings Tab, the Pulley setup is there also

    Thanks.....I gave up and went modbus in the end with run signal via the relay for safety. Works a treat.

    Yes, Modbus works the best of all methods, you did the right thing by using the relay, most don't and it's a safety risk they take.

    Thanks that's really good to hear. I wasn't sure if it was the right thing to do. Appreciate your help. Paul
