Resetting Converter Faults
In most cases, faults in the Converter are reset by resetting the Inverter. If
the condition causing the fault is still present, then a second fault is
generated and recorded in the fault queue. The only exception is a
checksum fault in the Converter. A checksum fault in the Converter is reset
by doing a reset defaults in the Converter, and then reset the fault in the
Inverter.
Clearing the fault queue in the Inverter does not affect the event queue in the
Converter. The Converter event queue is cleared independently of the
Inverter fault queue.
