If Capacitor failure detection is
set to Enable, the power module
(power unit) performs inverter
capacitor fault detection based on
the settings of Capacitor failure
detection upper limit and
Capacitor failure detection
lower limit. If the power module
determines that the inverter
capacitor is faulty, it shuts down
the inverter to prevent the fault
from expanding.
