Range of functions
Under C0960, you can select the function:
l
Characteristic with two interpolation points
l
Characteristic with three interpolation points
l
Characteristic with four interpolation points
The codes for entering the interpolation points can be obtained from the line diagrams.
Linear interpolation between the points.
For negative input values at CURVEx−IN, the settings of the interpolation points are processed
inversely (see line diagrams). If this is not desired:
l
Connect an absolute value generator (ABS) before or behind the CURVE function block
or
l
connect a limiter (LIM) before or behind the CURVE function block
