• Setting example of the conversion table for scaling
*1 When coordinates are specified using three points as shown in the points 4, 5 and 6, 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.
*2 When coordinates are specified using two points as shown in the points 8 and 9, 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.
In the case of the conversion characteristics for scaling shown in the figure below, set each value as shown in the following data table.

Error code
(SD0/SD8067)
Description
3405 The Xn data is not set in the ascending order in the data table.
However, the instructions before the occurrence of an error are executed.
The input value specified by (s1) is out of the range for the set scaling conversion data.
The value in the middle of operation exceeds the 32-bit data range.
In this case, verify that the distance between points is not "65535" or more.
If the distance is "65535" or more, reduce the distance between points.
The number of coordinate points from the device specified by (s2) is 0 or less.
