5.4.2 CC (Characteristics linearization)

Command
CC:I
A user defined signal characteristic can be set by this function. For activating the parameter CCMODE has to
be switched to ON.
The positive indexes stand for the solenoid A, the negative ones represent the solenoid B. The curve is calcu-
lated according to the equation of the linear interpolation: y=(x-x1)*(y1-y0)/(x1-x0)+y1.
The influence of the linearization can be estimated via the process data on the monitor or on the oscilloscope.
For the input of the characteristics linearization, the WPC-300 program provides a table and a graphic data
input. The input signal is mapped on to the X-axis and the output signal is mapped on to the Y-axis.
If the CC command is used, the TRIGGER of the MIN/MAX function should be set to 0 and the function
should not be used if possible. Both functions influence each other and make the behavior really diffi-
cult to evaluate.
