As a CAN bus based servo (RS485), the DJI 1240BA servo is also controllable via PWM.
1. When the servo is used to drive the EP robotic arm, it will be automatically switched to the CAN bus mode. The usage methods are as follows:
a) The default number of the servo is 1 or 2, but the robotic arm supports mounting three servos at one time. Therefore, when mounting three servos onto the robotic arm simultaneously, check if all servo numbers are correct. If not, modify one of the repetitive servo number to 3.
b) After the servo is connected to the robotic arm, it will not work normally unless the user clicks "Settings" - "Extension Module" – “Install Robotic Arm” in the RoboMaster app.
2. When used as an independent servo, PWM control or bus control can be used.
*After the servo is assembled as a mechanical arm, it cannot be controlled as an independent servo. To use it as an independent servo, you need to first remove the robotic arm in app-"Settings" - "Extension Module".
3. The bus mode and PWM mode will automatically switch according to the input signal without a need to be switched manually. The PWM signal is 50 Hz, and the 2.5%-12.5% duty cycle corresponds to 0-360 degrees.
