When using the ROS ur_robot_driver to send a trajectory to the UR controller, I am seeing a protective stop. The trajectory does not appear to have issues when sending it to the Controller.
In the UR log dump (log_history.txt) I am seeing this

The extremely large values for the velocities required seem to be causing some issues. I’m looking for some help in troubleshooting why the UR is reporting this. Also for why this message is appearing at all.
Thanks!
