Hi, now i configures SIMULINK about robot arm.
But in every time, the error is showed as above.
I wonder the reason why error appears and how to solve it.
I upload my SIMULINK file as zip file.
I use MATLAB 2022a version.
Also I attached dynamic equation what I used.
Thank you.

Most likely caused by the division-by-zero from this block. Could be triggered when the robot arm rotates to a certain angular position. Can you check the equations?
