Issue:
ATV312 fan strategy.

Product Line:
ATV312

Environment:
All models and serial numbers

Cause:
None

Resolution:
Before starting the fan the program subroutine management checks the temperature of the heat sink.
For the sizes 11KW or 15Kw if the temperature of the heat sink over than 50 degrees C the fan stars.
For the other sizes the fan starts at the temperature of 60 degrees C.
For all the sizes when the temperature of the IGBT are under than 40 degrees C the fan stops.
There is also a timer of 10s to keep the fan running a minimum.
