During
Run
This if the function of On/Off control of the fan attached for cooling the heat-sink of the inverter. This is used for
frequently starting/stopping loads or for a quiet environment without the noise of the cooling fan when stopping. This
also helps lengthen the life of the cooling fan.
No. 0 During Run (active during operation only) : If an operating command is input with the power ON in the
inverter, the cooling fan starts operating. If the operating command is OFF and the inverter output is blocked, the
cooling fan stops. If the temperature of the inverter heat sink is higher than a certain degree, the cooling fan operates
regardless of the operating command.
No. 1 Always ON (always active) : The cooling fan is always active when power is supplied to the inverter.
No. 2 Temp Control (temperature check) : The cooling fan is not active even when power is supplied to the
inverter and an operating command is input. However, if the temperature of the inverter heat sink is higher than a
certain degree, cooling fan is active.
Caution
Though 11~75kW class sets ADV-64 as “During Run”, FAN could be active as In case of operation
above regular temperature of cooling fan by current input harmonics or noises.
