Range of functions
Under C0960, you can select the function:
• Characteristic with two co-ordinates
• Characteristic with three co-ordinates
• 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:
• Connect absolute value generator (ABS) before or after the CURVE function block
or
• connect limiter (LIM) before or after the CURVE function block
