Understanding FANUC Robot System Variables FANUC robot system variables are a critical collection of data points that define how a robot controller operates, communicates, and manages its physical motion. These variables, which typically begin with a dollar sign (e.g., $MASTER_ENB
From the Teach Pendant:
While you need the official PDF for completeness, the following table provides a high-level reference to the most frequently accessed system variables. (Note: Variable names may vary slightly by software version.) fanuc robot system variables pdf
PROGRAM test_vars
VAR
status : INTEGER
BEGIN
-- Read system variable
GET_VAR(entry, '*SYSTEM*', '$MCR.$GENOVERRIDE', status)
-- Write new value
SET_VAR(entry, '*SYSTEM*', '$MCR.$GENOVERRIDE', 75, status)
END test_vars
$SCR_GRP[1].$M_POS_ENB: Enables/disables the display of the current position on the screen. $SCR_GRP[1]
The real power of having the FANUC system variables PDF is integrating these variables into automated logic. Don’t Scroll With thousands of variables
With thousands of variables, scrolling is impossible. Use the Type function by pressing [TYPE] or [FIND]. Type the variable name exactly as shown in the PDF (case sensitive? Usually upper-case with $ prefix). Example: $SCR.$AUTO_RUN
(Motion Control Record) manage robot speed overrides. Others, such as
