Boolean
Description: True
An MCU Inverter Fault is occurring.
False
No MCU Inverter Fault is occurring.
MCU inverter faults are power switch protection events. Too much heat or too much current can
damage the switches, so the MCU protects them and sets this bit while it is doing so. Too much
heat normally means that coolant loss has occurred, and the controller turns off the switches in
response. Too much current causes the controller to limit its torque by half.
