LED“00”digit: input phase lack protection selection
0: Invalid
1: Valid
Stop inverter output and alarm fault E.ILF while detect input phase lack.
LED“000”digit: output phase lack protection selection
0: Invalid
1: Valid
Stop inverter output and alarm fault E.oLF while detect output phase lack.

LED “0”digit: SC protection selection
0: Invalid
1: Valid.
Inverter judges E.SC alarm and removes distrubabce, only alarm for real fault signal. This function maybe
delay alarm time. Please ust it carefully.
LED“00”digit: OC protection selection
0: Invalid
1: Valid
Inverter judges OC alarm and remove distrubabce, only alarm for real fault signal. This function maybe delay
alarm time. Please ust it carefully.

Fan control
Setting range: 0-2
Factory set: 1
Select fan run mode.
0: Fan run after electrify
No matter temperature of module is high or not, fan runs while inverter power on.
1: Fan stop related to temperature
Work while running. While inverter stops, fan runs while module temperature is
over 50 degree and stops 30 seconds after module temperature is lower then standard. While inverter runs, fan runs.
2: Fan stop while machine stop, run related to temperature
While inverter runs, fan runs while module temperature
is over 50 degree and stops 30seconds after module temperature is lower then standard. While inverter is stops, fan
stops.
Note: This function can prolong fan life.

frequency add
Setting range: 0-50.00Hz
Factory set:2.00Hz
OV protection max frequency add:
Frequency inverter usually adds frequency to restrain the temperature rise while
bus voltage is higher than
[FA.06]
. It limits the frequency adding range.
Note: 1, Increase this value can better restrain, but if too big, the speed maybe shakeing. 2, If the bus voltage
