Hello. Thank you for your attention. It seems like my explanation is a bit lacking, so I ask again.
I'll explain the configuration of my device. First of all, it's not camera gimbal. I made an antenna tracker using the camera gimbal. The problem is that the camera IMU is far from the baseboard. To solve this problem I am using an extension of the standard cable. The basic cable is 50cm, but I am using it by extending it to about 200cm. That's why the alarm sounds every time I turn on the power. Every time I reset the IMU to solve the problem.
Hello, Yes, you can make cable longer, but each added meter of CAN cable decrease speed of CAN a little bit. We not recommend to use cable with length more than 3 meters. Also cable can receive interferences. Try to use shielded cable or use special copper sleeve for shielding, and connect only one end of shield to GND pin.
Hello, And one important note, we strongly recommend to use twisted pair for CAN_H and CAN_L lines (alike in original CAN cable): http://ybex.com/d/fvlhcbgzz9cy1uce65k3acz0wukp8m5pz0rh1tmi.html Try to use one entire piece of cable, without any internal connectors or soldered joints.
