3. AVR (Automatic Voltage Regulation) will determine actual output voltage, e.g. Fn_05=18:
a. Fn_48 = 0xxx, AVR will be effective, output voltage of inverter will be regulated as
follows:
Vmax = Fn_38 x Fn_30 , Vmid = Fn_40 x Fn_30 , Vmin = Fn_41 x Fn_30
b. Fn_48 = 1xxx, AVR will be ineffective, output voltage will vary with input
voltage:
Vmax = Fn_38 x Vin(input voltage), Vmid =Fn_40 x Vin ,
Vmin = Fn_41xVin
Fn_06 : Frequency output upper limit = 0 - 400Hz
Fn_07 : Frequency output lower limit = 0 - 400Hz
Remark
Internal

signal
Fn_06 (upper limit)
Fn_07 (lower limit)
Remark: If Fn_07=0Hz, Inverter output will stop when the frequency command is set to 0Hz.
If Fn_07 > 0Hz, Inverter output will run at the frequency by Fn_07 if frequency
command is lower than the frequency of Fn_07.
Multi-function output: Speed agreed detection
Fn_08 : Up-to frequency setting = 0 - 400Hz
Fn_09 : Up-to frequency setting detection with = 0 - 30Hz
Fn_61 : Multi-function output
= 00 : Run mode
= 01 : Up to desired freq.
= 02 : Set freq. Fout = Fn_08 +/- Fn_09
= 03 : Freq. detection Fout > Fn_08
= 04 : Freq. detection Fout < Fn_08
= 05 : over toque detection
= 06-11 : Change 00-05 (N/O) to (N/C)
