I/O_16 ~ I/O_25 (Ai2 ~ Ai3) setting method is the same as 1(Ai1) above.
The following figures are the example of 50% input gain and 25% of input bias for 0 ~ 10V analog input.
Maximum of the setting value depends on the Gain and starting point on the Bias. In the example above, Maximum
value is set to 50% by the Gain and starting point to 25% by the Bias. Consequently, 25 to 50% of the analog command
value is effective for 0 to 10V of input voltage.
