Data Content
The position data of slave axis is saved in E-cam table. (User
unit: PUU).
If E-cam is divided into N areas, the position of each area
must be included in the table. It must set N
＋1 points in total.
It is because the position of the first point (0 degree) and the
final point (360 degree) might not be the same.
If:
1. The start and final position is the same, it means after
the E-cam operating a cycle, the slave axis returns to
the origin position.
2. The start and final position is different, it means after the
E-cam operating a cycle, the slave axis does not return
to the origin position.
Operation
Description

the corresponding point to the P5-85 in E-cam table.
After engaging, if the master does not operate, the slave axis
will not operate. If the master operates, the slave will travel
according to the E-cam table.
