FANUC Fundamentals of CNC Robotics Operation 3

Question 1

Which FANUC motion type instruction moves the robot in a straight line between two points?

Accepted Answer

L (Linear)

Answer

The L motion instruction commands a linear (straight-line) path between the current position and the target.

Question 2

What does CNT (Continuous) termination type control in a FANUC TP program?

Accepted Answer

How closely the robot follows the exact programmed position before blending to the next

Answer

CNT 0–100 sets the corner rounding amount; CNT 0 passes through the point, CNT 100 maximizes the blend.

Question 3

In FANUC iRVision, what is a 2D single-view vision process primarily used for?

Accepted Answer

Locating parts on a flat surface using a single camera image

Answer

2D single-view processes detect part position and orientation from one camera image on a known plane.

Question 4

Which alarm code prefix on a FANUC controller indicates a servo system fault?

Accepted Answer

SRVO

Answer

Alarms beginning with SRVO relate to the servo drive and motor feedback systems.

Question 5

What is the effect of setting a register instruction PR[n] = LPOS in a FANUC TP program?

Accepted Answer

Saves the robot's current Cartesian position into position register n

Answer

LPOS captures the current Cartesian (linear) position and stores it into the specified position register.
