Problem of using CANopen control tens of motors in real time.

       I used THE PDO module of CANopen to control 16 motors, but the data reading speed was very slow, and the data displayed in the interface would be delayed (the value of the data read would not change in a period of time), so that when I used PID control, the motor Angle displayed in the data lagged behind the actual motor Angle.
       Especially when the number of motors increases, while a small number of motors will not lag in reading data.

       The same delay problem is encountered when the motor servo enabled.

Hi, @ytm1056147860,

So, in looking at your post, I can assume you are having trouble, but I (and everyone else) will have no idea what is happening in your code, as none of us can see your code.

 

Could you please attach your VI(s)?

 

Thank you!
