Inverter Functions
12.18 Controlling the Cooling Fan of
the Inverter
12.18.1
Selecting the Operation of the
Cooling Fan
• How to run the cooling fan of the inverter all the
time
• How to cool the inverter only while it is operating
• How to stop the sound of the inverter while it is not
operating
• How to cool the inverter only when it is generating
heat
• [bA-70] Setting the selection of the cooling fan
operation allows you to set the operation of the
cooling fan.
• For [bA-70]=00, the cooling fan runs all the time.
• For [bA-70]=01, the cooling fan runs when the
inverter becomes the output status. The fan runs
for three minutes after the operation stops.
• For [bA-70]=02, the cooling fan runs depending on
the temperature of the head sink detected by the
inverter.
Parameters
• For checking the head sink temperature, see
"13.9.1 Checking the Head Sink Temperature".
• For the replacement timing of the cooling fan, see
"13.11.1 Checking the Life Cycle Monitor".
• When the instantaneous power failure or power-off
occurs while the cooling fan is running, it is
suspended regardless of the [bA-70] cooling fan
operation, and automatically resumes after the
restoration of power.

00
Running all the time:
The fan runs all the time.
01
Running in operation:
The fan runs automatically when the inverter becomes the
operating status. The fan continuously runs for three minutes
after the operation stops and then automatically stops.
* The cooling fan runs when the head sink temperature of
the inverter exceeds 60°C.
If the head sink temperature is
under 50°C for more than three minutes, the cooling fan is
allowed to be stopped.
02
Running depending on the temperature:
The cooling fan runs when the head sink temperature of the
inverter exceeds 40°C. If the head sink temperature is under
40°C for more than three minutes, the cooling fan
automatically stops.
