Broken-line approximation is used to correct non-linearity in the input.
Twenty broken-line approximation points can be set for input 1.
To use broken-line approximation, set the Broken-line Approximation
enabled parameter to "ON" (the default setting is OFF).
Broken-line approximation includes the Broken-Line Approximation 1
Inputs 1 to 20 and Broken-line Approximation 1 Outputs 1 to 20
parameters. Normalized data is used to set the values so that the
lower limit of the input setting range for input 1 is 0.000 and the upper
limit is 1.000.
• Normalized data is used to set the values for broken-line approxi-
mation so that the lower limit of the input setting range for input 1 is
0.000 and the upper limit is 1.000. For example, if the input type of
input 1 is J (2) ( 20.0 to 400.0°C) and the broken-line approximation
is to be applied to one point, 210.0°C, the values are set as follows:

Broken-line Approximation 1 Input 1 = 0.000
Broken-line Approximation 1 Output 1 = 0.000
Broken-line Approximation 1 Input 2 = 0.500
Broken-line Approximation 1 Output 2 = 0.750
Broken-line Approximation 1 Input 3 = 1.000
Broken-line Approximation 1 Output 3 = 1.000
