Your take on CAN...

[johnmaguire2013]

I don't understand motors, electricity, etc. however I have a question on behalf of my team, and I think I'm wording this correctly.

Basically, we used CAN with Jaguars for our robot's drivetrain this year. Multiple times it stopped working during the match, and our team was seemingly able to determine that this was due to built-in protection on the Jaguar to stop, essentially, surges. It was happening when a large amount of voltage was sent through the Jaguar I believe, and our team said this wouldn't be an issue if we switched back to PWMs. It would usually happen if our driver was moving back and forth very quickly (e.g. the bridge.) Does anyone have an idea of what was happening or how this could be fixed?
