As for using multiple drivers at the same time, the cascade mode is CN6A in and CN6B out.
Failure to follow the cascade mode of up in and down out may lead to abnormal communication.
Please try to ensure that the length of the cascaded cable is less than 50cm, and the CN6B of the
last one should be connected with the terminal resistance (Only CANopen bus/ Mechatrolink-II
bus/ RS-485 bus should be considered with terminal resistance).
