I would like to elaborate on this. You are correct that whenever the Jag reboots/resets (usually after a brown-out or a power cycle) all parameters and running modes are reset to default (voltage mode) except for the ID. However, overheating and over current won't necessarily reset the Jaguar. The Jaguar will go into a fault mode and shut off the outputs for a few seconds (to attempt to alleviate the problem) and then pick up right where it left off.

That being said, it is definitely possible for an over current condition to happen so fast that the Jaguar can't fault in time. The current spike can dip the supply voltage so much that the Jaguar browns out and therefore resets.
