6.20 Useful functions
6.20.1 Cooling fan operation selection (Pr. 244)
You can control the operation of the cooling fan (FR-D720S-070SC or more, FR-D740-036SC
or more) built in the inverter.
The above parameter can be set when Pr. 160 = 0.
In either of the following cases, fan operation is regarded as faulty, "FN" is shown on the oper-
ation panel, and the fan fault "FAN" and alarm "LF" signals are output.
Pr. 244 = 0
When the fan comes to a stop with power on.
Pr. 244 = 1
When the fan stops during the fan ON command while the inverter is running.
For the terminal used for FAN signal output, set "25" (source logic) or "125" (sink logic) to any
of Pr. 190, Pr. 192 or Pr. 197 "Output terminal function selection", and for the LF signal, set "98"
(source logic) or "198" (sink logic).
