Which FANUC motion type instruction moves the robot in a straight line between two points?
Answer: L (Linear)
The L motion instruction commands a linear (straight-line) path between the current position and the target.
What does CNT (Continuous) termination type control in a FANUC TP program?
Answer: How closely the robot follows the exact programmed position before blending to the next
CNT 0–100 sets the corner rounding amount; CNT 0 passes through the point, CNT 100 maximizes the blend.
In FANUC iRVision, what is a 2D single-view vision process primarily used for?
Answer: Locating parts on a flat surface using a single camera image
2D single-view processes detect part position and orientation from one camera image on a known plane.
Which alarm code prefix on a FANUC controller indicates a servo system fault?
Answer: SRVO
Alarms beginning with SRVO relate to the servo drive and motor feedback systems.
What is the effect of setting a register instruction PR[n] = LPOS in a FANUC TP program?
Answer: Saves the robot's current Cartesian position into position register n
LPOS captures the current Cartesian (linear) position and stores it into the specified position register.
Which FANUC safety zone type triggers a stop only when the robot TCP exits a defined boundary?
Answer: DCS Cartesian position check (outside stop)
An 'outside stop' DCS Cartesian position check halts the robot if the TCP moves outside the defined safe volume.
What information is stored in the FANUC TP program's header section?
Answer: Program attributes such as group mask, write protect, and comment
The program header holds metadata including the motion group mask, protection settings, and descriptive comments.
