Web19 Sep 2009 · PWM involves the modulation of a signals duty cycle. In controlling a servo, the duty cycle does not control the position of a servo. Servo position is controlled through modulating the on time of the pulse. Indeed it is possible to control a servo over its full range of movement by changing the on time but keeping the duty cycle constant. Web26 Feb 2024 · In some servo motors, a 20% duty cycle of a 20 ms square wave will rotate the shaft in 180 degrees while a 10% duty cycle will reset it to its original position. PWM duty cycle determines how the servo motor rotates. The beauty of PWM is that it’s far more efficient than applying analog voltage.
