*1 With the exception of positioning control, main cycle processing is executed during the next available time. It changes by status of axis
start.

[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)
4: Read (Cam storage 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.

3.2 Create Cam Data
• Write operation: Set the cam data corresponding to the
cam data format.
• Read operation: The cam data is stored.
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.
The data is read from the cam storage area and stored to the buffer memory.
The data is written to the cam open area from the cam storage area.
All the buffer memories of "[Cd.607] Cam data value" are cleared to 0.
