Programming & Software Integration Flashcards

In FANUC's line tracking (conveyor tracking) system, what is the role of the 'tracking window'?

Answer: It specifies the conveyor distance range within which the robot can initiate and complete a pick

The tracking window defines the upstream and downstream conveyor distance boundaries within which the robot must start and finish its pick/place operation relative to the detected part.

Which FANUC program instruction is used to read the current value of a digital input signal into a register?

Answer: R[1]=DI[5]

In FANUC TP, assignment syntax 'R[n]=DI[m]' directly copies the state of digital input m (0 or 1) into numeric register n.

What distinguishes a FANUC Macro program from a standard TP program?

Answer: Macros can be called like built-in instructions, accept arguments, and can run in the background without appearing in the motion stack

Macro programs can be registered to execute like system instructions, accept up to ten arguments via AR[] registers, and are typically used for utility tasks that don't need to appear in the foreground program stack.

In FANUC iRVision, what is a 'Locate Tool' and what does it output?

Answer: A vision process that finds a part's position and returns offset data for use in robot programs

A Locate Tool is an iRVision vision process that identifies a taught part model in a camera image and outputs position and orientation offset data that the robot program uses to adjust its pick position.

When a FANUC controller executes a 'WAIT 2.00 (sec)' instruction, what happens to the motion queue?

Answer: All motion is suspended and the robot holds its current position for 2 seconds before continuing

A WAIT time instruction is a blocking dwell that suspends program execution, holding the robot stationary at its current position for the specified duration.

Which file extension is used for FANUC TP program binary files that are native to the controller's memory?

Answer: .TP

FANUC TP programs are stored in binary format with the .TP extension on the controller; .LS files are the human-readable ASCII listing format used for backup and review.

In a FANUC multi-group system, what does 'independent motion' mode allow compared to coordinated motion mode?

Answer: Each motion group executes its own motion path simultaneously but without maintaining a fixed spatial relationship between groups

Independent motion allows multiple motion groups to move concurrently on separate, unsynchronized paths, unlike coordinated motion which maintains a rigid kinematic relationship between groups.
