(1) There are two searching methods that depend on whether SM750 is on or off.
(2) When the scaling conversion data are set in ascending order, the searching methods change from one to the other
depending on the SM750 status. Therefore, the processing speed also changes. The number of searches determines
the processing speed. Fewer number of serches make the processing run faster.
(a)
If the data processing speed with the sequential search rises:
If the number of coordinates is highest and the input value
is within the coordinate range from 1 to 15 point,
the number of sequential searches will be 15 or smaller. Therefore, the data processing speed with the
sequential search will rise.
(b)
If the data processing speed with the binary search rises:
If the maximum number of searches is 15 and the input value
is out of the coordinate range, 16 or over, the
number of binary searches will be equal to the number of sequential numbers or smaller. Therefore, the data
processing speed with the binary search will rise.

The X coordinates of the scaling conversion data positioned before the
point specified in are not set in ascending order. (However, this error
is not detected when SM750 is on.)
The input value specified in is not within the range of the scaling
conversion data set.
The number of X and Y coordinates of the device specified in is not
within the range from 1 to 32767.

The processing speed with sequential searches
rises since the number of binary searches is
larger than the number of sequential searches.
The processing speed with binary search
rises since the number of binary searches is
smaller than the number of sequential searches.
