Full alert identifier: DIRER_a034_phaseBcurrentSensor

Alert description

The Drive Inverter (DIx) Phase B current sensor is irrational.

Potential impact

If the alert asserts at the beginning of a drive cycle, DIx may not enable. If the alert asserts during a drive cycle, DIx may be disabled. DIx may not function as expected.

Set condition

The DIx Phase B current sensor is irrational. An irrational current may indicate a high rate of change or current measurement out of sensing bounds. There may be a condition affecting current input and output.
