I know that in the old system, in the Firmware for the jaguars, if it did not recieve a new packet for 100ms, it would shut itself off.

Also, I have heard that the PWM's don't just turn off, they actually all get set to 0 by the FPGA. I would suspect something similar happens on the CAN bus as well. It probably just sends a 0 to all motors on the bus. Easy to implement and makes sense.
