Here takes the each AI terminal as examples to show how to use the AI terminal to control the main frequency reference.
Example 1: To make the voltage input at AI1 to control the frequency reference and correspond 2 to 10 V to 10 to 40 Hz, the settings

Note:
2 to 10 V corresponds to 20.0% to 80.0%.
100.0% corresponds to max. frequency (F0-10 = 50.00 Hz).
