Chapter 3 Cam Function
(3) Coordinate data format
The coordinate data format is defined in coordinates of more than 2 points for one
cam cycle. The coordinate data is represented as "(Input value, Output value)".
• Input value : Cam axis current value per cycle
• Output value : Stroke position from cam reference position
With this format, "[Pr.441] Cam stroke amount" of output axis parameter is ignored
and output value of the coordinate data becomes cam stroke position.
Refer to Section 3.2 "Create cam data" for setting methods of cam data.
