3 CAM FUNCTION
3.1 Control Details for Cam Function
Cam data
The cam data used in the cam function includes "storage data" which is used for reading/writing with the engineering tool and
"open data" which is transmitted to the internal memory at cam control.
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.
■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.
