MODE (of the linearization) W.E.ST. Elektronik GmbH Commands Parameter Defaults Units mode x x= on|off off - This command ist used for activation or deactivation of the characteristic linearization defined by the CC command. To test the linearization it can be useful to deactivate this function. CC (characteristic linearization) Commands Parameter Defaults Units cc:i x y i= -10… 10 x= -10000… 10000 y= -10000… 10000 - - - 0,01% 0,01% A user defined characteristic can be used by this function. The characteristic linearization defines positive values for the linearization of channel A and negative values for channel B. Ten XY-points per solenoid are possible. Every curve function is calculated according to the equation (linear interpolating between the points: y=(xx1)*(y1-y0)/x1-x0)+y1) . With the command MODE ON|OFF the linearization function can be activated or deactivated. The characteristic between the input and the function CC can be considered by the process variables U to C in the monitor / oscilloscope. Caution: The table must be filled completely always from the top (10 then 9 then 8… and/or -10 then -9 then -8…). The lower unused range can be filled with cc:i 0 0. Example: Flow characteristics as a square function.
