Example 2: On the condition that current input from AI2 is available, if 0 to 20 mA is input,
it corresponds to voltage input of 0 to 10 V. If 4 to 20 mA is input, it corresponds to voltage
input of 2 to 10 V.
To make current input at AI2 to control frequency reference and correspond 4 to 20 mA to
0 to 50 Hz, the settings are shown in the following figure.
