The minimum resolution of the time value is 0.1 seconds.
PWM Zero Defines the time period for the Zero position pulse. When the on time of the PWM period is at this value the
PWM device will position itself to the zero position.
PWM Full Defines the time period for the Full position pulse. When the on time of the PWM period is at this value the
PwM device will position itself to the full position.
