Unformatted text preview: duty cycle should vary. a. What is the frequency of the PWM signal? 1 b. What is the maximum duty cycle? Minimum? What about at the neutral position? Is this what you expected? Any hypotheses why these are like this? c. What is the voltage the PWM signal operates at? d. What is the risetime? Falltime? DC motor wiring checked by the lab instructor. 15. Using a multi-meter, look at the voltages that drive the motor. a. What is the voltage range as you vary the joystick position? b. Is this voltage linear with joystick position? c. Does this correspond to what you saw the PWM signal you saw earlier? Why or why not? 16. Comment on the switching between brake and coast modes. How long does the motor take to stop in the Brake mode? How long for the coast mode? Digital inputs checked. Radio link checked. Extra Program down load successfully performed. What happens when you have 2 identical team numbers? 2 Other comments and observations 3...
