AIO_15 expresses the minimum current input that can be recognized by the
inverter in a percentage to the maximum input current (20 mA). For example, if
AIO_15 is set to 20%, this stands for 4 mA in current. If AIO_15 is set to 0%, any
input to the analog input terminal that is smaller than 4 mA is not regarded as an
effective input.
AIO_15 is used to define the range of current input at the analog input terminals.
In general, AIO_16 is set to 0%, and AIO_18 is set to 100%. However, for those
analog input devices that generate chattering with 0% AIO_15 setting value, you
may adjust the value to avoid the chattering.
When the main controller receives current inputs at the analog input terminals,
inaccuracy of the analog input or output devices may create deviations in the
signals. AIO_16 and AIO_18 are similar to bias and gain settings which are used
to correct the deviation in the inverter’s main controller.

Out Y2)
Setting the bias at AIO_04 (Ai1 Out Y1)
Connect voltage or current input source to multifunction analog terminals V1
through GND, and set AIO_03 to 0%. Provide 0 V input, and then follow the
instructions below to adjust analog input bias.
