5.2 Variable speed control (pin 14)
This function lets you control your spindle with step and direction signals, as if it was an axis motor. It converts the step signal into an analog (0-10VDC).
My BOB is wired to the PWM terminals on the motor controller. Wire from BOB #14 to the controller PWM terminal, and a wire from BOB relay (controlled by pin #16) to the controller F/R Dir terminal. I'm lost. Is my BOB controlling the spindle with a PWM, or a stepgen generating out a PWM signal?
I appreciate your taking the time to respond.
Thanks,
