Presenter - Erin Meyer DMC recently developed a program for the 1517-TF PLC that utilized the Siemens LAxis function block library to control 15 axes of S120 servo motion. The features utilized included a Virtual Master axis, point to point motion, velocity motion, electronic gearing, and electronic camming. The drives were configured to utilize PROFISafe functions including STO and SS1 functionality. Topics covered will include: considerations made when selecting the 1500T platform, a summary of the new features on the 1500T, and an overview of the software design, implementation, and commissioning process utilized to successfully start up the machine in TIA Portal v14. This includes developing code using the LAxis library and Profisafe, using Starter to commission the drives, and testing and starting up the various axis configurations. Tips, tricks, and lessons learned will also be presented

- In the example, the slave carousel has to rotate at a 2:1 ratio to the master carousel to keep the cans flowing through.
- Returning cams are analogous to the valve lifting cam in an internal combustion engine. Incrementing cams continue to move with every cycle. Something that is very difficult to duplicate mechanically.
- Example : filling a bottle. Position is watched, when it reaches a certain position,
