Inverter shows FAN alarm when fan is damaged.
1X
Inverter don’t alarm when fan is damaged, but the output
terminal which is set to function 16 will output a signal.
X0
Fan turn on when inverter starts running. Fan turn off 30
seconds after inverter stops.
X1
Fan turn on when inverter power on. Fan turn off when
inverter power off.
X2
Fan turn on if heat sink temperature is higher than 40℃. Fan
turn off when inverter power off.
X3
Fan turn on if heat sink temperature is higher than 60℃. Fan
turn off when heat sink temperature is lower than 40℃.
Cooling fan operation mode
Ten bits of 06-12(P.245) are used to switch alarm output mode.
Each bit of 06-12(P.245) is used to specify run/stop condition.
Example:
If “Fan turn on when inverter power on. Fan turn off when inverter power off” and “Inverter don’t alarm
when fan is damaged, but the output terminal which is set to function 16 will output a signal” is needed, then
06-12(P.245) should be set to 11.
Note: According to the installation environment conditions of inverter, if fan can be operated for as little time as possible
through reasonable setting, service life of fan can be prolonged.
