Limp mode via CAN

If some sort of parameter were to be able to cause the VESC to enter Limp mode, via a signal over CAN, it would allow for the hardware to protect itself.



An implementation of this could be considered with a BMS. If a CAN enabled BMS could communicate to the VESC, triggering a limp mode, in which acceleration cannot be increased, and braking ability remains, this could prevent a hard cut-off being reached, or possible hardware failure (eg a battery fire due to severely discharged P group).
