A file containing one RAPID module, not an entire RobotStudio station.

Mechanism Jog Joint

A RobotStudio jogging method that uses entered values to position individual robot axes precisely.

Freehand Jog Joint

A RobotStudio method that moves robot joints by dragging them graphically; a Virtual Controller is not required.

Freehand Jog Linear

A RobotStudio method that translates the active TCP in a straight line along selected coordinate axes.

Freehand Jog Reorient

A RobotStudio method that rotates the tool around the active TCP; it requires an active Virtual Controller in the course context.

Jump Home

A simulation command that returns the graphical robot mechanism to its original neutral or home pose.

Joint jogging

Moving individual robot axes or joints.

Linear jogging

Moving the active TCP in a straight line along a selected coordinate axis.

Reorient jogging

Rotating the tool's orientation around the active TCP.

Predefined data

Data supplied by ABB and ready to use, such as v50, z100, and tool0.

User data

Data created and named by the programmer, such as pMyLocation.

num

A RAPID data type that stores numbers used in calculations.

string

A RAPID data type that stores text.

bool

A RAPID data type that stores TRUE or FALSE.

robtarget

A RAPID data type that stores a robot target's position, orientation, and configuration.

tooldata

A RAPID data type that stores a tool's TCP and load information.

wobjdata

A RAPID data type that stores workobject and user-coordinate-system information.

speeddata

A RAPID data type that specifies robot motion speed, such as v50.

zonedata

A RAPID data type that controls how the robot passes through a target, such as fine or z10.

VAR

An ordinary changeable variable whose latest value should not be expected to survive a restart.

PERS

A persistent changeable variable whose updated value is retained after a restart.

CONST

A constant whose value cannot change after it is declared.

Declaration

A statement that introduces a data name, data type, and sometimes an initial value.

Assignment operator (:=)

The RAPID symbol used to assign a value to data.

Ambiguous data reference

A condition in which the controller cannot uniquely identify an item because conflicting names are visible in more than one scope.

Turning disk / mounting flange

The mounting surface at the end of the robot wrist where a tool is attached.

tool0

The robot's default tool at the turning disk or flange; it cannot be deleted.

TCP (Tool Center Point)

The exact point on the active tool that the controller positions at a programmed robtarget.

Four-point TCP method

A method that calculates the TCP by placing the same tool tip at one fixed point using four different wrist orientations.

TCP offset

The TCP's position relative to the robot's mounting flange.

Tool load

The mass and center-of-gravity information associated with a robot tool.

Payload

The part or material carried by the robot or its tool.

LoadIdentify

An ABB service routine used to identify the mass and center of gravity of a tool or payload.

World coordinate system

A coordinate frame fixed to the entire cell and used as a common reference for robots and equipment.

Base coordinate system

A coordinate frame attached to the robot base and used for robot-relative positioning.

Workobject / user coordinate system

A coordinate frame attached to a part, fixture, or work area so programmed points follow that frame.

Tool coordinate system

A coordinate frame attached to the active TCP and aligned with the tool's orientation.

Task

The controller execution context containing system modules and program modules.

Module

A RAPID text file that groups data declarations and routines.

System module

A controller-wide module containing support code and data that remains loaded when programs are changed.

Program module

An application-specific module that contains RAPID code and the global main procedure.

Routine

A callable block of RAPID code; types include procedures, functions, and traps.

Procedure (PROC)

A routine that performs a sequence of instructions when called.

Function (FUNC)

A routine that performs operations and returns a value.

Trap (TRAP)

A special routine executed in response to an interrupt.

main

The required global entry procedure where normal RAPID program execution begins.

MoveJ

A RAPID instruction that moves the robot using joint-interpolated motion; useful for efficient travel between separated areas.

MoveL

A RAPID instruction that moves the active TCP along a straight path; useful for controlled approaches and retreats.

fine

A stop-point zone value requiring the robot to reach the target precisely before continuing.

z10

A zone value that allows the robot to blend smoothly through or near a target without fully stopping.

\WObj

An optional RAPID motion-instruction argument used to select a workobject.

SetDO

A RAPID instruction used to set the state of a digital output, such as a gripper command.

WaitTime

A RAPID instruction that pauses program execution for a specified time.

Approach point

A safe target before an action point that allows the robot to enter the work area predictably.

Action point

The exact target where the robot performs an operation, such as gripping or releasing a part.

Retreat point

A safe target used to move the tool away after completing an operation.

Modular programming

Organizing a program into separate reusable routines and modules that are easier to test and modify.

Syntax error

Invalid grammar, spelling, punctuation, commas, or semicolons in code.

Semantic error

A valid-looking statement that uses the wrong name, data type, argument order, or meaning.

Logic error

Code that runs without a controller error but performs the wrong action or sequence.

Program Pointer (PP)

The controller marker identifying the next RAPID instruction to execute.

PP to main

A command that resets the Program Pointer to the beginning of main.

PP to cursor

A command that moves the Program Pointer to a selected line and should be used only when appropriate or instructed.

Calibration position

A known mechanical reference position where the robot's axis calibration marks align.

Home position

A programmed or simulated safe position that is not automatically the same as calibration position.

Enabling device

A manual-mode safety control that permits motion in its middle position; releasing or over-squeezing it stops motion.
