Introduction
This comprehensive examination is designed to rigorously assess the knowledge and practical skills required of a
certified FANUC robot technician and programmer. The test evaluates a candidate's proficiency across a spectrum of
domains, from fundamental safety protocols and system architecture to advanced programming, troubleshooting, and
application-specific setup. It employs a multiple-choice format, including scenario-based questions that challenge the
candidate to apply theoretical knowledge to real-world industrial situations, emphasizing sound decision-making and
,effective problem-solving. The questions reflect the critical balance between operational efficiency, regulatory
compliance, and unwavering adherence to professional and ethical standards in robotic automation.
SECTION ONE: QUESTIONS 1 – 100
1. What is the primary function of the Deadman Switch on a FANUC Teach Pendant?
A. To activate high-speed operation modes
B. To enable servo power only when the switch is held in the mid-position
C. To perform a controlled emergency stop of the robot
D. To toggle between manual and auto modes
🟢 B. To enable servo power only when the switch is held in the mid-position
🔴 Explanation: The Deadman switch (or enabling device) is a safety-critical feature. It must be held in its mid-
position to enable servo power to the robot during manual operation. Releasing it or squeezing it completely will
disable servo power, preventing unintended motion.
2. Which of the following is the correct coordinate system for defining robot motion relative to the tool center
point (TCP)?
A. Joint
B. World
C. Tool
D. User
🟢 C. Tool
,🔴 Explanation: The Tool coordinate system is centered on the TCP. Motions defined in this system move the tool
along its own X, Y, and Z axes and rotate about them, which is intuitive for tasks like welding or sealing.
3. In a FANUC controller, what is the function of the BMON (Boot Monitor) menu?
A. To edit user programs
B. To adjust motor parameters during run-time
C. To perform low-level system tasks like installing software or formatting memory
D. To monitor the status of input/output signals
🟢 C. To perform low-level system tasks like installing software or formatting memory
🔴 Explanation: The BMON menu is a pre-boot environment used for system-level maintenance and recovery. It is
not accessible during normal operation and is used for installing software options, formatting the memory card, or
recovering the system from a failed startup.
4. A robot program uses a PR[1] position register. The value is taught as a "USER" frame. If the User Frame is later
redefined, what happens to the robot's motion to PR[1]?
A. The robot will move to the same physical point in space.
B. The robot will move to a new point, offset by the change in the User Frame.
C. The program will generate an alarm.
D. The position register value will automatically update to the new frame.
🟢 B. The robot will move to a new point, offset by the change in the User Frame.
🔴 Explanation: Position registers store location data relative to a specific coordinate frame (User, Tool, World). If the
User Frame is redefined, the numeric values in PR[1] remain the same, but they now reference a different physical
origin and orientation, causing the robot to move to a different point in space.
, 5. What is the primary purpose of the "FINE" termination type for a motion instruction?
A. To smooth the path between two motions
B. To ensure the robot passes exactly through the taught point
C. To increase the speed of the robot's acceleration
D. To extend the life of the servomotors
🟢 B. To ensure the robot passes exactly through the taught point
🔴 Explanation: 'FINE' termination forces the robot to reach the exact programmed point and come to a complete
stop before executing the next instruction. It is used when precision at a specific point is critical. In contrast, 'CNT'
(Continuous) blends the paths.
6. When performing a "Cold Start" on a FANUC R-30iB controller, which of the following typically occurs?
A. The robot loads the system from a backup image
B. The robot performs a full power cycle, clearing all volatile memory
C. The robot performs a controlled shut-down and restart, preserving register values
D. The robot reloads all default system variables
🟢 C. The robot performs a controlled shut-down and restart, preserving register values
🔴 Explanation: A controlled 'Cold Start' is the standard power-on process for a FANUC controller. It safely shuts
down the operating system and then restarts it, preserving critical system variables and the state of non-volatile
memory. A 'Power-Up' or 'Controlled Start' may clear some memory.
7. A weld schedule is being set up. Which of the following parameters is NOT typically controlled by the FANUC
ArcTool application?
A. Wire feed speed
B. Welding voltage
