This parameter determines if the cooling fan for the drive will always

 

operate or only run when the temperature of the inverter exceeds the

 

protective temperature limit.

 

 

 

 

 

 

 

 

 

0 = Always ON, cooling fan operates when power is applied to drive. Fan

 

turns off when inverter voltage becomes low due to power off.

 

1 = Fan operates when temp above limit; fan begins to operate when power

 

is ON and a operating command is ON. Fan turns off when operating

 

command is turned off. Fan will continue to operate if the heat sink

 

temperature exceeds a certain limit regardless of operating command. Use

This parameter determines if what the drive will do if the cooling fan fails.

0 = Continuous operation when cooling fan malfunctions

Setting t32 or t33 = 18 (Cooling Fan Fault Alarm) will send an alarm signal to the output.

ATTENTION: If operation is continued after a fan trip occurs, an overheat trip may happen and protective functions may be activated. It may also reduce the life of main board components due to a rise in inverter internal temperatures.
