Which FANUC robot axis is responsible for the rotation of the wrist roll?
Answer: J6
J6 controls wrist roll rotation, allowing the end-of-arm tooling to spin about the tool centerpoint.
What does the FANUC system variable $PARAM_GROUP[ ].$PAYLOAD represent?
Answer: The maximum tool load in kilograms
$PAYLOAD stores the maximum allowable tool payload in kilograms for the motion group.
In FANUC Karel, which statement is used to pause program execution for a specified number of seconds?
Answer: DELAY
The DELAY statement in Karel halts execution for a defined duration before continuing.
What is the purpose of the FANUC DCS (Dual Check Safety) function?
Answer: To provide hardware-level position and speed monitoring independent of the main CPU
DCS monitors joint positions and speeds on a dedicated safety CPU, triggering a stop if limits are violated.
Which coordinate frame is fixed to the robot's end-of-arm tooling and moves with it?
Answer: Tool frame
The tool frame (TCP) is defined relative to the robot flange and translates/rotates with the tool.
On a FANUC teach pendant, pressing SHIFT + RESET performs which action?
Answer: Releases a fault and resets alarms
SHIFT + RESET clears active faults and alarm conditions so normal operation can resume.
What is the function of the FANUC background logic (BG Logic) feature?
Answer: Runs Karel programs that execute concurrently with the main motion task
BG Logic allows Karel programs to run as background tasks simultaneously with foreground motion programs.
