current limited run. Inverter reduces current by reduce output frequency actively. Temperature be limited within70 ℃
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.

Protection function selection 4
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
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.

Running OV protection point
Inverter DC bus rated voltage=inverter input rated voltage
DEC OV protection: Set OV protection point while DEC. Only valid while [FA.01] LED "0" digit is 1.
Running OV protection point: Set OV protection point while ACC or running at constant speed. Only valid while
[FA.01] LED "0" digit is 1.

frequency add
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
