PARAMETERS

4.2.44 Cooling fan operation selection (Pr. 244)

Pr. 244 "cooling fan operation selection"

You can control the operation of the cooling fan built in the inverter (whether there is a

cooling fan or not depends on the models. Refer to the outline dimensional drawings

(page 193)).

In either of the following cases, fan operation is regarded as faulty, [FN] is shown on the

operation 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.

Setting Description

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.)

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.
