Processing details
• Of the cam No. data specified with (S1), the (S3) cam data of the (n) number of points, starting from the position specified
with (S2), is read. The read cam data is stored in the device specified with (D) or later. However, (S2) and (n) are ignored
when an auto-generation format cam is read.
• Set the cam data first position specified with (S2) within the following range.

Coordinate data format
*1 Since the stroke ratio of the zeroth point cam data is fixed at 0%, the cam data cannot be read.
• Specify the number of read points for (n). Specify the number of read points so that the device No. storing the end point
data is within the range. The following shows the operation when the number of read points, starting from the first position,
is outside the cam data range.

• The device No. specified with (D) should be an even number. The read cam data is stored in the specified device according
to the cam data format as follows.

Operation
If the value calculated from "(S2) + (n) - 1" is larger than the cam resolution, the cam data, ranging from the cam data first position
to the cam resolution, is read.
If the value calculated from "(S2) + (n)" is larger than the number of coordinates, the cam data, ranging from the cam data first
position to the last coordinate, is read.
