Function
l
A linear interpolation is carried out between the co−ordinates.
l
For negative values at CURVE1−IN, setting values of the interpolation points are processed as
inverted values (see diagrams).
– If this is not desired, add an ABS or a LIM function block in front of or behind the CURVE
function block.
