Suppose (to keep things simple) the camera is producing 24 pulses per second, what should the motor be doing in response to that.
And, perhaps more important at this stage, what would be unacceptable behaviour by the motor?
Am I correct to assume that there will either be 24 pulses per second (camera running) or no pulses at all (camera stopped)?
What is the motor required to do when the pulses start and stop?
It would be a big help if you explain the purpose of the motor.
