The FANUC controller supports up to eight motion groups.

• A. True
• B. False
• C. Depends on model
• D. Not specified

Answer: (A)

Motion groups organize axes into separate parallel control channels on a FANUC controller, letting different sets of drives be commanded independently while sharing the same system. This setup supports complex multi-axis machines by isolating motion tasks and their parameters, so changes in one group don’t affect others. The upper limit commonly supported is eight groups, so stating that the controller can handle up to eight motion groups is accurate for typical configurations. Some older models or specific options might use fewer groups, but eight is the widely cited maximum.
