• If the operation result is not an integer, the number in the first decimal place is rounded off.
• Set the X coordinate data of the scaling conversion data in the ascending order.
• Set (s1) within the scaling conversion data range (device value of (s2)).
• If the same X coordinate is specified by multiple points, the Y coordinate value of the point whose number is the largest is
output.
• Set the number of coordinate points for the scaling conversion data within the range of 1 to 65535.
• Setting example of the conversion table for scaling
In the case of the conversion characteristics for scaling shown in the figure below, set each value as shown in the following data table.
