8-5 Cooling Fan Control
[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.
Precautions for Correct Use
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.
Parameter
• For checking the head sink temperature, see 5-7 Cooling Fin Temperature Monitor on page 5-14.
• For the replacement timing of the cooling fan, see 5-9 Life Monitor on page 5-17.

01
Running in operation:
The fan runs automatically when the inverter
becomes the operating status. The fan con-
tinuously 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.
