Description
This alert is reported by the MotorDiagnostics_R12 (MD) component if the difference between estimated and measured phase currents is greater than the limit or the QoS of the phase currents is QOS_CS_ERROR or the qualifier of the estimated phase currents is SEN_NOT_AVAILABLE for longer than the given debounce time.
Condition
EPAS model diagnostics detects integrity failure on the observed motor behavior to a theoretical motor model (phase cuts or short circuit of the phase relays failures).
Clear Condition
EPAS power cycle.
Potential Impact
