FANUC Fundamentals of CNC Robotics Operation 2

Question 1

Which FANUC robot axis is responsible for the rotation of the wrist roll?

Accepted Answer

J6

Answer

J6 controls wrist roll rotation, allowing the end-of-arm tooling to spin about the tool centerpoint.

Question 2

What does the FANUC system variable $PARAM_GROUP[ ].$PAYLOAD represent?

Accepted Answer

The maximum tool load in kilograms

Answer

$PAYLOAD stores the maximum allowable tool payload in kilograms for the motion group.

Question 3

In FANUC Karel, which statement is used to pause program execution for a specified number of seconds?

Accepted Answer

DELAY

Answer

The DELAY statement in Karel halts execution for a defined duration before continuing.

Question 4

What is the purpose of the FANUC DCS (Dual Check Safety) function?

Accepted Answer

To provide hardware-level position and speed monitoring independent of the main CPU

Answer

DCS monitors joint positions and speeds on a dedicated safety CPU, triggering a stop if limits are violated.

Question 5

Which coordinate frame is fixed to the robot's end-of-arm tooling and moves with it?

Accepted Answer

Tool frame

Answer

The tool frame (TCP) is defined relative to the robot flange and translates/rotates with the tool.
