Cam data operation by file transmission function

Cam data can be written from a cam file to the cam open area by specifying cam data using "File transmission request
(SD820)".
Refer to the following for details of the file transmission function.

Instruction Description
Cam data read This is used to read cam data.
Cam data can be read from a cam file by setting the destination reading. The upper amount of
data for each operation is 32768 points (2 words are used per point) with the stroke ratio data
format, and 16384 points (4 words are used per point) with the coordinate data format.
If the read is not completed in one time, the operation should be separated in multiple times.
Cam data write This is used to write cam data to the CAM open area.
Cam data can be saved in a cam file by setting the destination for writing.
The upper amount of data for each operation is 32768 points (2 words are used per point) with
the stroke ratio data format, and 16384 points (4 words are used per point) with the coordinate
data format.
If the write is not completed in one time, the operation should be separated in multiple times.
Cam auto-generation This function is used to automatically generate cam data for specific purposes by setting data for
function auto-generation.
Auto-generation cam data is generated in the stroke ratio format in the cam open area, and the
data for auto-generation can be saved in a cam file by setting the destination for writing.
It is possible to generate up to 16Mbytes including the regular cam data.
(Example)
1024 cam data (with the stroke ratio format, resolution is 4096) can be automatically generated.
