The FANUC controller supports up to how many motion groups?

• A. Eight
• B. Ten
• C. Four
• D. Six

Answer: (A)

Motion groups are separate control domains that let a FANUC controller run independent sets of axes or motion tasks in parallel. The controller’s architecture is designed to support up to eight of these groups, so you can organize a complex cell or multi-tool operation into eight independent motion domains without interference. This maximum reflects the balance of available motion interpolation resources and the software interpreter capabilities. Because eight is the documented limit, it allows eight concurrent trajectories or tool/group configurations, while more groups would exceed what the hardware/software can reliably manage. Using fewer groups would unnecessarily constrain parallel motion capabilities.
