FANUC system variables are memory locations within the robot controller (

: Represents the global speed override percentage (0% to 100%) showing on the top right of the teach pendant screen. It can be modified dynamically via background programs or I/O.

), coordinate systems (Tool, User, and Jog frames), and override configurations ( $OVRD_SETUP ) fall into this category. Access and Security Accessing these variables is typically done through the Teach Pendant by navigating to [MENU] > [NEXT] > [SYSTEM] > [Variables] . However, not all variables are editable: Read-Only (RO):

: Manages the behavior of Direct Memory Access and can influence how background tasks interact with the main motion task. 4. Setup and Configuration Variables

), these variables are stored in the controller's CMOS memory and can range from single integers to complex data structures containing diagnostic and configuration data. Categories and Functions

Turn the controller power back on while holding the keys until the configuration menu appears. Select . Navigate to the SYSTEM -> VARIABLES screen. Make the necessary modifications. FANUC system variables are memory locations within the

: An open-source documentation repository provides the "FANUC Robotics R-J3 System Variables Reference Manual," offering detailed variable definitions, scope information, value ranges, and practical guidance.

They can be single values (integers, reals, strings) or complex structures (arrays and structures containing sub-variables).

Finally, variables like $SCR_GRP[group].$MCH_POS provide real-time robot position and speed, while $SEMIPOWERFL controls "hot start" functionality to resume programs after a power loss. Access and Security Accessing these variables is typically

A common repository for finding digitized versions of the variable lists.
