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
≤
...
≤
x
i
≤
...
≤
x
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.
