3.2 Terms
| Term | Definition of Term |
| Asset management | The management of the maintenance of physical assets of an organization throughout each asset's lifecycle. |
| Automatic mode | Operational mode in which the robot control system operates in accordance with the task programme (ISO 10218). |
| Axis | The mechanical joint (ISO 8373). Joint is used as a synonym for axis. |
| Condition monitoring | Acquisition and processing of information and data that indicate the state of a machine over time (ISO 13372:2012). |
| Controller | Controlling unit of one or more motion devices. A controller can be e.g. a specific control cabinet or a PLC. |
| Industrial robot | Automatically controlled, reprogrammable multipurpose manipulator, programmable in three or more axes, which can be either fixed in place or mobile for use in industrial automation applications (ISO 10218). |
| Industrial Robot System | system comprising industrial robot, end effectors and any machinery, equipment, devices, external auxiliary axes or sensors supporting the robot performing its task (ISO 8373) |
| Joint | See Axis definition. |
| Manipulator | Machine in which the mechanism usually consists of a series of segments, jointed or sliding relative to one another, for the purpose of grasping and/or moving objects (pieces or tools) usually in several degrees of freedom (ISO 8373) |
| Manual mode | Control state that allows for the direct control by an operator (ISO 10218). |
| Motion device | A motion device has as least one axis and is a multifunctional manipulator designed to move material, parts, tools, or specialized devices through variable programmed motions for the performance of a variety of tasks. Examples are an industrial robot, positioner, or mobile platform. |
| Motion device system | The entire system in which one or more motion devices and one or more controllers are integrated, e.g. a robot system. |
| Operating mode | State of the robot control system (ISO 8373), i.e. Controller |
| Operational mode | ISO 10218-1:2011 Ch.5.7 Operational Modes |
| Operator | Person designated to start, monitor, and stop the intended operation of a robot or robot system (ISO 8373). |
| Teach pendant | Hand-held unit linked to the control system with which a robot can be programmed or moved (ISO 8373). |
| Power train | The composition of switch gears, fuses, transformers, converters, drives, motors, encoders and gears to convert power to motion of one or more axis. |
| Predictive maintenance | Maintenance performed as governed by condition monitoring programmes (ISO 13372:2012) |
| Preventive maintenance | Maintenance performed according to a fixed schedule, or according to a prescribed criterion, that detects or prevents degradation of a functional structure, system or component, in order to sustain or extend its useful life. |
| Protective stop | Type of interruption of operation that allows a cessation of motion for safeguarding purposes, and which retains the programme logic to facilitate a restart (ISO 10218). |
| Safe state | A defined state of the robot which is free of hazards |
| Safety function | A safety rated function which will signal the controller to bring motion devices to a safe state, e.g. emergency stop, protective stop |
| Safety states | Set of safety functions and states which are related to a motion device system. |
| Software | Runtime software or firmware of the controller. In ISO 8373, this is called control program, and is defined like this: Inherent set of control instructions which defines the capabilities, actions and responses of a robot or robot system NOTE This type of program is usually generated before installation and can only be modified thereafter by the manufacturer. |
| Task control | Execution engine that loads and runs task programs. Synonyms for a task control are a sequence control or a flow control. |
| Task module | A module is a self-contained unit of code that can be reused across different parts of a program or in different programs. |
| Task program | Program running on the task control. From ISO 8373: Set of instructions for motion and auxiliary functions that define the specific intended task of the robot or robot system NOTE 1 This type of program is usually generated after the installation of the robot and can be modified by a trained person under defined conditions. NOTE 2 An application is a general area of work; a task is specific within the application. |
| Tool center point | Point defined for a given application with regards to the mechanical interface coordinate system (ISO 8373) |
| User level | Current assigned user role. |
| User roles | User roles consist of specific permissions to access features within a software. Users can be assigned to roles. |
| Virtual axis | Virtual axis has no power trains directly assigned. |
