IGBT (Insulated Gate Bipolar
Transistor) case
temperature is too hot
(over the limit).
Note: The temperature is
calculated using a thermal
model
Ensure all module fans are
operating.
Ensure the ambient
temperature is not too high.
The IGBT junction is too hot
(near limit).
Note: The temperature is
calculated using a thermal
model.
