to correct the frequency, and the frequency is corrected after the inverter stops. The value is cleared to
zero.
● The tens place of F0.13 is 0 (the stop frequency is maintained), set the digital frequency of F0.05 with the
panel, and then correct the frequency through the up and down keys of the keyboard or terminals UP
and DOWN, and the frequency correction value after the inverter stops is reserved.

8.2.3 Analog quantity setting main frequency (AI1 , AI2 setting )
Set the main frequency through the analog input AI1, AI2, each AI terminal can set the corresponding AI
curve, the specific setting steps are as follows:
● AI curve setting method:
There are 2 types of AI curves, among which, curve 1 corresponds to AI1, and curve 2 corresponds to AI2,
both of which are 2-point curves, and the relevant parameters are F5.27～F5.34.

(Step 1) AI terminal as a frequency source:
Select the AI input terminal of the frequency
command according to the terminal
characteristics
F0.02
Main frequency selection:
F 0.02=1: AI1 terminal input to set the main
frequency
F 0.02=2: AI2 terminal input to set the main
frequency
(Step 2) AI curve setting method:
set the corresponding relationship between the
input of AI voltage/current and the set value
