While you can view variables on the Teach Pendant under Menu → System → Variables , having a PDF is critical for complex work. Your best source is from FANUC directly, but here is a list of specific, commonly referenced PDFs that cover system variables across different controller generations:
: Controls the manual jog speed override percentage.
To get the most accurate and detailed list of variables, you should access the documentation provided by FANUC America or FANUC Europe. Searching for "FANUC System Variables PDF," "FANUC R-30iB System Variables," or looking into specialized forums will help you find specific manuals tailored to your robot controller, such as the R-J3iB or R-30iB models.
The Role and Management of FANUC Robot System Variables FANUC robot system variables are the foundational internal parameters that dictate how a controller operates, handles data, and interacts with external hardware. Often identified by a leading dollar sign (e.g., $OVRD_SETUP fanuc robot system variables pdf
: System variable structures change between older controllers (e.g., R-J3iB) and modern controllers (R-30iB Plus). Never assume an exact sub-variable index maps identically across different core software versions. 6. Downloading a System Variables PDF
| Variable | Description | Data Type | | --- | --- | --- | | $POS | Current position | Position | | $TCP | Tool Center Point | Position | | $ER | Error code | Integer | | $MODE | Operation mode | String | | $IO | I/O signal status | Integer | | $MAX_SPEED | Maximum speed | Real | | $ACCEL | Acceleration and deceleration rates | Real | | $FLAG[1] | Flag indicating reaching a certain position | Boolean | | $FLAG[2] | Flag indicating an error occurrence | Boolean |
(Motion Control Record) manage the robot's speed override settings. Other variables, such as $AC_CRC_ACCO While you can view variables on the Teach
Scroll through the alphabetical list using the arrow keys or use the function to locate a specific variable.
They can be single values (integers, reals, strings) or complex structures (arrays and structures containing sub-variables).
: Keep a manual log of the original value, the modified value, the date, and the reason for the change. Searching for "FANUC System Variables PDF," "FANUC R-30iB
, store dynamic mastering records for specific motion groups. System Configuration
FANUC robot system variables are the backbone of robot configuration, motion control, and software integration. These internal parameters govern everything from hardware communication and axis limits to user interface behavior and error handling. Understanding how to navigate, modify, and document these variables is essential for any robotics engineer or integrator. What Are FANUC System Variables?
Displays the robot's current TCP position in World coordinates.
$MASTER_DONE : Indicates if the mastering procedure has been completed (1) or not (0).
