 =  : Cooling fan automatically controlled. Cooling fan operates only when the ambient temperature is
 =  : Cooling fan not automatically controlled. Fan is always running when the inverter is on.

Torque (%)
When  =  (tripping), the inverter will trip if over-torque lasts for the period of time set with
 . In such a case, the over-torque signal remains ON.
Set to operate the fan only when the ambient temperature is high during operation. When the inverter
is on, the service life of the cooling fan is longer than if it is always running.
high during operation.
If the ambient temperature is high, even when the inverter is stopped, the cooling fan automatically
operates.
