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