You can control the operation of the cooling fan built in the inverter 0.75K or more.
(whether there is a cooling fan or not depends on the models. Refer to the outline

Operated at power on (independent of whether the inverter is running or at
a stop).

Cooling fan on-off control valid
(The cooling fan is always on while the inverter is running. During a stop,
the inverter status is monitored and the fan switches on-off according to
temperature.)
<Reference>
In either of the following cases, fan operation is regarded as faulty, [FN] is shown on
the control panel, and the minor fault (LF) signal is output. Use any of Pr. 190 to
Pr. 192 (output terminal function selection) to allocate the terminal used to output the
LF signal.
1) Pr. 244 = "0"
When the fan comes to a stop with power on.
2) Pr. 244 = "1"
When the inverter is running and the fan stops during fan ON command or the fan
starts during fan OFF command.
Note:
When the terminal assignment is changed using Pr. 190 to Pr. 192, the other
functions may be affected. Confirm the functions of the corresponding
terminals before making settings.
