To help you work with them, it's crucial to understand their key attributes. The official reference manuals break down every variable using a standardized table, which typically includes details like the Minimum , Default , and Maximum values, Data Type , and a Description . A particularly important attribute is , which tells you exactly what you can do with each variable:
(if you have a login). But don’t expect it to teach you robotics – it’s a dense, technical lookup table. Keep it open while programming, and always back up your robot’s variables before making changes. fanuc robot system variables pdf
These variables control how the robot moves and defines its kinematics.
If you are currently troubleshooting an error or configuring a specific application, let me know you are setting up (e.g., paletizing, welding, vision) or the exact variable you need to modify.

Press , choose Set Device , and select your USB drive ( UD1: or UT1: ). Press F4 [BACKUP] and select System Variables . This creates a file named SYSVARS.SV on your USB drive. Step 2: Export as Readable Text ( SYSVARS.TX )
: Many system variables require a Cold Start (power down and power up) to take effect. A particularly important attribute is , which tells
Below I summarize the important categories, typical variables, practical uses, and where to look in the FANUC PDF documentation — so you can use the official PDFs effectively.
$MCR.$GENOVERRIDE : Controls the overall robot override speed percentage (0% to 100%).
System variables are exceptionally powerful when used in .
Read-only variables will reject modification attempts with an error message. Additionally, many system variables require a power cycle or controlled start to become effective after modification.
