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
(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.
■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.
