Toshiba VF-A7 Cooling fan control mode selection, Cumulative operation time alarm

Setting value



Adjustment range

＝(Disabled)・・・・does not trip (FL is not active).

＝(Enabled)・・・・The inverter trips if a torque larger than (during power

running) or (during regeneration) passes for a time longer than the time set with .

6.25.10 Cooling fan control mode selection

 ：Cooling fan control mode

・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.

＝：Automatic control of cooling fan, enabled. Operates only when the inverter is in operation.

＝：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.

6.25.11 Cumulative operation time alarm

 ：Cumulative operation time alarm setting

・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.

＊Panel display of  corresponds to 10 hours. If  is displayed, the cumulative operation time is 3855 hours.
