Notes:
1) PWM ports are located on the chassis control module. To access them, remove the transparent cover.
There are six PWM ports in total.
2) PWM (pulse width modulation) controls the duration of a high level of output during a certain period, and
is broadly used to control LEDs, navigation gears, and more.
3) For LEDs, the PWM output rate ranges from 0% to 100%, with 0% corresponding to an LED’s lowest
brightness and 100% to its highest brightness.
4) For navigation gears, the PWM output rate ranges from 2.5% to 12.5%. Because most navigation gears
have a control impulse frequency of 50Hz and a control period of 20 ms, and because the high-level pulse
width of outputs with an adjustable angle range of -90°to 90° ranges from 0.5ms to 2.5ms, control of the
navigation gear’s duty ratio ranges from 0.5/20 to 2.5/20, which is to say from 2.5% to 12.5%.
You can set the navigation gear PWM output percentage based on the rotation angles you wish to control.
