When
f615 = 1 (tripping), the inverter will trip if over-torque lasts for the period of time set with
f618. In such a case, the over-torque signal remains ON.
6.24.11 Cooling fan control selection
f620 : Cooling fan ON/OFF control
Function
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.
f620=0: Cooling fan automatically controlled. Cooling fan operates only when the ambient temperature is
high during operation.
f620=1: Cooling fan not automatically controlled. Fan is always running when the inverter is on.
+ If the ambient temperature is high, even when the inverter is stopped, the cooling fan automatically
operates.
