l Characteristic with two co-ordinates
l Characteristic with three co-ordinates
l Characteristic with four co-ordinates
The codes for entering the co-ordinates can be obtained from the line diagrams.
A linear interpolation is carried out between the co-ordinates.
For negative input values at CURVEx-IN, the settings of the co-ordinates are processed inversely
(see line diagrams).If this is not required:
l Connect absolute value generator (ABS) before or after the CURVE function block
or
l Connect limiter (LIM) before or after the CURVE function block
