Step 2: Select a required curve for AI terminal.
F4-33 selects curve of AI1, AI2 and AI3 from the five curves, respectively. Curve 1, curve
2 and curve 3 are 2-point curves, set in group F4. Curve 4 and curve 5 are 4-point curves,
set in group A6.
The drive provides two AI terminals (AI1, AI2). An extra AI terminal (AI3) is provided by
the I/O extension card.

F4-22 AI2 filter time
F4-27 AI3 filter time
F4-17, F4-22 and F4-27 set AI software filter time. If analog input is liable to interference,
increase this parameter to stabilize detected analog input. But too large a setting slows
response of analog detection. Set it correctly based on actual conditions.
Step 3: Select a required AI terminal as main frequency reference setting channel.
The AC drive provides two AI terminals (AI1, AI2). An extra AI terminal (AI3) is provided by
the I/O extension card.
Here takes each AI terminal as examples to show how to use AI terminal to control main
frequency reference.
Example 1: To make voltage input at AI1 to control frequency reference and correspond 2
to 10 V to 10 to 40 Hz, the settings are shown in the following figure.
