We have a black box motor controller that takes a 0-5V analog signal and turns it into (I think) a PWM input to a 48V, 60A motor. Suffice it to say the motor needs enough power to make it impractical for me to just make my own controller.
We have another system that generates a PWM motor control signal. So here's the question: can I just hook the PWM output of this system into the analog input of the black box? Will that work just like if we had supplied the actual analog voltage?
If not, is there a particularly easy way to turn PWM into an analog voltage?
