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.
