6. CAM FUNCTION

6.1 Control Details for Cam Function

The output axis for synchronous control is operated with a cam.
The following operations can be performed with cam functions.
• Two-way operation : Reciprocating operation with a constant cam strokes range.
• Feed operation
• Linear operation
The output axis is controlled by a value (current feed value), which is converted from
the input value (cam axis current value per cycle) by cam data.
