17.1.67.1 Function 3: nOut_a = f(table)
If function 3 has been selected in
, the output value is calculated according to a
characteristic.
• The characteristic may comprise up to 32 interpolation points which are defined by parameters.
• If the
nIn_a
input value is equal to one of the X interpolation points, the corresponding Y
interpolation point will be output to
nOut_a
.
• If the
nIn_a
input value lies between two X interpolation points, the
nOut_a
output value will
be interpolated linearly:
[17-22] Linear interpolation between two interpolation points
