  Automatic control of cooling fan, disabled. The cooling fan always operates
when the inverter is energized.
The cooling fan automatically operates whenever the ambient temperature is
high, even when the inverter is out of operation.

Function
With this parameter, you can set the condition of cooling fan so that it operates only when
the inverter requires cooling, and thus it can be used for a longer period of.
Function
This parameter is to make a setting so that the inverter puts out a signal when it
s cumulative operation time has reached the time set with this parameter.
