5.16.1 Roll Diameter Calibration

This parameter group allows the user to configure the parameters for calibrate the roll diameter measuring by analog input AI1, AI2, AI3 or AI4. Through the choice of two points, where each point is represented by the actual roll diameter and the analog input AIx value, is obtained the line equation, thus allowing a good linearity in the reading of the roll diameter value. The graph below illustrates how it is done to calibrate the roll diameter.

Figure 5.1 – Graph with points to roll diameter calibration

Through the roll diameter value and the analog input Aix value for point 1 and point 2, is obtained the line equation of the roll diameter:
