Setting Description
0 Operated at power on (independently of whether the inverter is running or at a stop).
1
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 operation panel, and
the fan fault (FAN) and light fault (LF) signals are output. Use Pr. 190 to Pr. 195 (multi-function outputs) to
allocate the terminals used to output the FAN and LF signals.
1) Pr. 244 = "0"
When the fan comes to a stop with power on.
2) Pr. 244 = "1"
When the fan stops during the fan ON command while the inverter is running, or when the fan starts
during the fan OFF command.
Note: When the terminal functions are changed using Pr. 190 to Pr. 195, the other functions may be
affected. Confirm the functions of the corresponding terminals before making setting.
