Point 1
• 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 values of (s2) and (s2)+1).
• 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 4294967295.
• 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.

Remarks
When coordinates are specified using three points in this way,
the output value can be set to an intermediate value.
In this example, the output value (intermediate value) is
specified by the Y coordinate of the point 5.
Even if the X coordinate is the same at three points or more, the
value at the second point is output.
When coordinates are specified using two points in this way, the
output value is the Y coordinate at the next point.
In this example, the output value is specified by the Y
coordinate of the point 9.
