1. A motor controller for an electric motor of a drive system, said motor controller comprising:
an inverter configured to supply current to stator windings of the electric motor;
a plurality of sensors configured to generate a sensor signal in response to detecting a parameter, the sensor signal representing a measured parameter;
a processor coupled in communication with said inverter and with said plurality of sensors, said processor configured to:
in a first mode, transmit a control signal to said inverter to operate the electric motor at a first frequency;
receive the sensor signal from said plurality of sensors; and
determine a first fault condition is present based on the measured parameter represented by the sensor signal, wherein the first fault condition indicates a fault within the drive system.
