Re: PWM translates to movement?
I got everything you explained except this part:
"but the output actually stays at zero for at least the theoretical 0-6 range, and it reaches 100 with an incoming pulse width that is somewhat less than 2.0 ms. It turns 1.0-1.5 milliseconds into a 100-0 reverse value, with the same holding at zero until it reaches 7 or so, and getting to 100 before the pulse width gets down to 1.0 ms."
Could you explain that a little more, what is the theoretical 0 - 6 range? does this mean there there is another IC chip that translates the pwm signals to a seperate pulsed signal that contains forward and reverse for the FETs? are there IC chips out there that are already programed to do that? I don't want to run into programming it etc...
Also, if I am switching current on a solenoid quickly, to prevent arcing, is it possible that I hook up two diodes in parallel but in opposite directions? is there a better solution to this other than using diodes? I know people use diodes to lessen the EMF from the collapsing field, but if im constantly creating, destroying fields, how would I handle the EMF? with currents up to something like 40 amps..
