Operation selection function parameters

CAUTION

Do not reset the inverter with the start signal on.

Otherwise, the motor will start instantly after resetting, leading to potentially hazardous conditions.

2.10.6 Cooling fan operation selection (Pr. 76 )

You can control the operation of the cooling fan built in the inverter (whether there is a cooling fan or not depends on the model.).

Setting Description

0Operated at power on (independent of whether the inverter is running or at a stop). Cooling fan ON/OFF control valid

Always on during inverter operation

1During stop (reset or error), the inverter status is monitored and the fan is switched on/off according to the temperature.

•Heatsink temperature is less than 40oC (104oF) .............Cooling fan off

•Heatsink temperature is not less than 40oC (104oF) .......Cooling fan on

REMARKS

In either of the following cases, fan operation is regarded as faulty, is shown on the operation panel, and the minor fault (LF) signal is output. Use any of Pr. 64, Pr. 65 (output terminal function selection) to allocate the terminal used to output the LF signal.*

•Pr. 76 = "0"

When the fan comes to a stop with power on.

•Pr. 76 = "1"

When the inverter is running and the fan stops during fan ON command.

CAUTION

*When the terminal assignment is changed using Pr. 64, Pr. 65, the other functions may be affected. Confirm the functions of the corresponding terminals before making settings.
