[Cd.600] Cam data operation request
Set the following commands to write/read cam data.
Setting value
1: Read (Cam open area)
2: Write (Cam storage area)
3: Write (Cam open area)
The setting value is reset to "0" automatically after completion of cam data operation.
If a warning occurs when requesting cam data operation, the warning No. is stored in "[Md.24] Axis warning No." of axis 1,
and the setting value is reset to "0" automatically.
When another request command is set, the operation does not get executed and the setting value is reset to "0" automatically.
[Cd.601] Operation cam No.
Set the cam No. to write/read.
[Cd.602] Cam data first position
Set the first position of the cam data to write/read.
Set the cam data first position within the range from 1 to the cam resolution in cam resolution units using the stroke ratio data
format. The stroke ratio of the 0th cam data is 0% fixed, and this data cannot be written/read.
Set a value within the range from 0 to (Coordinate number - 1) with the coordinate data format.
When writing the new cam data with the coordinate data format, make sure to set "0", and write the data from the 0th point. If
a value other than "0" is specified, the cam data before the specified position becomes undefined, and the cam data of the
corresponding No. may not be operated.
[Cd.603] Number of cam data operation points
Set the number of operation points to write/read starting from the first position of cam data.
• Stroke ratio data format
The following shows the operation details when the value of "Cam data first position + Cam data operation points - 1" is larger
than the cam resolution in the stroke ratio data format.

Details
The cam data is read from the cam open area and stored to the buffer memory.
The cam data is written to the cam storage area and the cam open area from the buffer memory.
The cam data is written to the cam open area from the buffer memory.
Details
The cam data from the first position to the cam resolution is read in the buffer memory.
"Outside number of cam data operation points range" (warning code: 0E93H) occurs, and writing is not executed.
Details
The cam data from the first position to the last coordinate is read in the buffer memory.
"Outside number of cam data operation points range" (warning code: 0E93H) occurs, and writing is not executed.
