The FG instruction interpolators f(x) value for x based on the n parameters of (x
i
,y
i
).
For example, if XW04 is 1500 (x = 1500), the result 1405 (f(x) = 1405) is stored in D0100.
Note
• The order of the x parameters should be x
1
≤
x
2
≤

i
≤

n
. In the above example, the
data of D0600 to D0603 should be D0600 ≤ D0601 ≤ D0602 ≤ D0603.
• If x is smaller than x
1
, y
1
is given as f(x). In this example, D0604 data (-1800) is stored in
D0100 if XW04 is smaller than D0600 (-2000).
• If x is greater than x
n
, y
n
is given as f(x). In this example, D0607 data (1800) is stored in
D0100 if XW04 is greater than D0603 (2000).
• The valid data range is -32768 to 32767.
