■Stroke ratio data format
The stroke ratio data format is defined in equal divisions for one cam cycle based on the cam resolution, and configured with
stroke ratio data from points within the cam resolution.
Refer to the following for setting methods for cam data.

Setting item Setting details
Cam No. Set the cam No.
Cam data format Set "1".
(Setting with the engineering tool is not
required.)
Cam resolution Set the number of divisions for one cam
cycle.
Cam data starting Set the cam data point corresponding to
point "Cam axis position value per cycle = 0".
Stroke ratio data Set the stroke ratio from the 1st to the last
point.
(The 0th point setting is not required. It is
always 0%.)
*1 To display the stroke ratio out of range 100%, select the "Simple Motion" of "Intelligent Function Module" and set "Yes" to the "Display
Extended Stroke of Cam Graph" on the "Options" window displayed by the menu bar of the engineering tool [Tool]  [Options].
