Linearization by specifying bias
The input values for linear approximation are the breakpoint settings A1 to A10,
the bias values for linear approximation are the breakpoint settings B1 to B10, and
the output values are A1 + B1 to A10 + B10, and these appear as shown in the graph
below.
Input at A1 or before results in output of a value equal to Input value + B1.
Input at A10 or after results in output of a value equal to Input value + B10.

For B1–B10, upward arrows mean a positive value,
and downward arrows mean a negative value.

Example using linear approximation by analog input
This is an example of using linear approximation of one linearization table for
analog input of slot A4.
The input for 0.0 to 100.0 is converted to 0.0 to 100.0 for a separate characteristic.
(1) Specify the groups of the linearization table in the analog input bank.
