"Cam axis current 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 For setting the stroke ratio out of range 100% with the engineering tool (Simple Motion Module Setting Function), check the "Display
