A standard reference point for motion controllersJul 30, 2018
Understanding the differences between the coordinate frames and how they interact with each other is the key to accomplishing successful motion using groups. In Part 4 of PLCopen, the global standard for motion control on IEC 61131-3 programmable controllers, the concept of multi-axis coordinated moves using groups was introduced. Groups are collections of axes on a common mechanism that work together to provide a path of travel in 3-D space. Examples include gantry systems, articulated arm robots, delta robots, or linkage mechanisms; any device where multiple axes work together to provide multi-dimensional motion.
