Cam data
The cam data used in the cam function includes "storage data" which is used for reading/writing with EM Configurator and
"open data" which is transmitted to the internal memory at cam control.
Storage data
 (Reading and writing not possible)
Stroke ratio data format
Auto-generation data format
Coordinate data format
Storage data and open data are same for cams using the stroke ratio data format and the coordinate data format. A cam using
the auto-generation data format (storage data) operates after being changed (transmitted) to the stroke ratio data format.
• Data read/written with the engineering tool
To re-edit the cam data read from the Simple Motion module/Motion module with the engineering tool, read/write both of "cam
data (edit data)" and "cam data (converted data)" when reading/writing the cam data. If only "cam data (conversion data)" is
read/written, re-edition may not be executed or the information such as units and strokes may be missed.
■Linear cam control
When "0" is set for "[Pr.440] Cam No.", the cam data operates as a straight line with a 100% stroke ratio at the last point.
The linear cam does not consume the cam open area. Also, it cannot be read/written as storage data.
