An output open-phase is
detected at less than 5% of
Inverter rated current.
When the applied motor capacity
is small compared to the Inverter
capacity, the detection may not
work properly and should be disabled.
Set the ON/OFF control for the
cooling fan.
0: ON when Inverter is
running only
1: ON whenever power is ON
2: When the temperature
exceeds L8-21 setting.
Set the time in seconds to delay
turning OFF the cooling fan after
the inverter STOP command is
given. (Valid only if L8-10 = 0)
