A rotating solar panel, follows the position of the sun in the sky. Accordingly, the panel rotates one full revolution per day. The rotation mechanism consists of a stepper motor with 50 steps per revolution and a gearbox with a gear ratio of 393.9. The motor is using half stepping. What must the control signal frequency be for the solar panel to rotate one full revolution per 24 hours? The mechanism running for 12 days in a row (using half-stepping) he notices a slight inaccuracy in the system. The mechanism has turned 10.5 revolutions during that time. What's the real frequency of the step signal?
