Function 17 - Polynomial (POL)
Operation
This block executes mathematical operations established by the functions 0, 1 or 2, as shown in the
Figure. The function is selected in parameter
CTYP:
CTYP = 0 A-B difference.
CTYP = 1 4th-order polynomial.
CTYP = 2 3-input sum.
Inputs
A, B, C and coefficient K
0
are interpreted as percentages, while coefficients K
1
to K
4
are real
numbers. Inputs and output may range from -102.00 to +102.00%.
Inputs are standardized as follows:
