Ost_The servo angle is determined by the pulse width in a 50 Hz PWM signal. Most servos move to 0 when they receive a pulse 1500 µs long. Generally it is safe to send a servo a pulse in the range 1000 µs to 2000 µs.A frequency or period is specific to controlling a particular servo. Typically, a servo motor anticipates an update every 20 ms with a pulse between 1 ms and 2 ms. This equates to a duty cycle of 5% to 10% at 50 Hz. Now, if the pulse is at 1.5 ms, the servo motor will be at 90-degrees, at 1 ms, 0-degrees, and at 2 ms, 180 degrees.Duty cycle simplified If the valve is pulsed ON at variable durations (called pulse-width modulation), the duty cycle varies.
