The $KAREL_ENB system variable controls whether KAREL programs appear in the program list. When set to , KAREL program types become visible. When set to 0 , they are hidden. This variable can be changed without requiring a controller restart.
System variables can be used in robot programs to perform a variety of tasks, such as:
When encountering pulse coder mismatch alarms (SRVO-038, SRVO-062, SRVO-063), follow this procedure: fanuc robot system variables pdf
These variables dictate how the robot moves, handles speed overrides, and recovers from stops.
: Some variables are hidden or restricted for safety reasons. Unauthorized modification of critical parameters can lead to equipment damage or personnel injury. Reference Manuals & Resources This variable can be changed without requiring a
: Reflects the current general speed override percentage changed by the and buttons.
The hundreds of system variables are organized into logical categories based on what part of the system they control. Unauthorized modification of critical parameters can lead to

$PR[x] : Position Registers. While modified via code, their structural properties reside in system memory. 3. Error Handling and System State
FANUC robot system variables are the named memory locations and parameters inside a FANUC robot controller that store runtime state, configuration, and control values. They let programs, I/O logic, and system utilities read or change controller behavior without rewriting RAPID-like programs (for FANUC this is TP/TP+ or KAREL programs). Documentation is commonly distributed as PDF reference manuals that list each variable, its type, access rules, valid ranges, default values, and notes about when/where it’s supported.
