6. 30. 11 Cooling fan control
<F620: Cooling fan control>
■ Function
The cooling fan run only when the ambient temperature is high and during run. This way, the service
life of cooling fan can be extended compared to when keep running the cooling fan while the power
is ON. It is also able to trip when the capability of the cooling fan falls below a certain level. The trip
display is "E-42".
■ Parameter setting
*When the motor speed of the cooling fan is lower than a certain level, cooling fan fault alarm can be
output from the output terminal regardless of the setting in <F620>.
■ Selecting a setting value
0: Auto ON/OFF, No failure detection
Cooling fan is automatically controlled. Cooling fan operates only when the ambient temperature is
high and during run.
Cooling fan operates automatically, if the ambient temperature is high, even when the inverter is in a
stop.
1: Always ON, No failure detection
Cooling fan runs all the time when the inverter is on.
Trip does not occur at the time of the cooling fan failure. (Failure signal FL disabled)
2: Auto ON/OFF, Failure detection
Cooling fan is automatically controlled. Cooling fan runs only when the ambient temperature is high
and during operation.
When the motor speed of the cooling fan is lower than a certain level, a trip occurs. (Failure signal
FL enabled)
3: Always ON, Failure detection
Cooling fan runs all the time when the inverter is on.
