    Vbb?

    Just received my Xylotex 4 axis board and power supply today. Connected the ac cord to power supply, adjusted output voltage to 26.1 vdc(under 27vdc per instructions). I guess the next step is setting driver output. What does VBB mean? Any input will be appreciated for the next steps. Nick

    VBB is the terminal for connecting the motor power supply DC voltage, 26.1V in your case.

    What actually does VBB stand for. I assume V is voltage. What does BB mean?
    thanks.

    Vbb - bulk bias voltage
    vref - reference voltage
