(Note-1): The range from axis 1 to 2 is valid in the 2-axis module, from axis 1 to 4 is valid in the 4-axis module, from axis 1 to 8 is valid in the
8-axis module, and from axis 1 to 16 is valid in the 16-axis module.
Example
The following shows a procedure of aligning the synchronous position of an output axis
that references the input axis.
1) Set the following values in the synchronous control initial position parameters.

[Pr.462] Cam axis position restoration object
[Pr.463] Setting method of cam reference position
[Pr.464] Setting method of cam axis current value per cycle
