Does the cRio cut motors at 5.5Vdc on CAN?

[dyanoshak]

Both Gray and Black Jaguars will indicate a Power Supply Under Voltage fault (slow blink red on the LED) when the power supply drops below 6V. The Jaguar is still on at this point, it just shuts off the motor outputs.

The Gray Jaguar will shut down completely after the voltage drops close to and below ~3.3V. The Black Jaguar will shut down completely after the voltage drops below 5.5V.

The time between a voltage fault and total shutdown can be quite fast, especially under sudden heavy loads.

If a Jaguar resets, all parameters will reset (control mode, trusted enabled, etc.). If the CRIO somehow managed to stay on while a Jaguar reset, it would have to reestablish a trusted link to the Jaguar and reset all the parameters. Joe might be able to chime in with a suggestion on how to deal with this particular situation.
