GLOSSARY
Category 0 stop: Robot motion is stopped by immediate removal of power to the robot. It is an uncontrolled
stop, where the robot can deviate from the programmed path as each joint brake as fast as possible. This
protective stop is used if a safety-related limit is exceeded or in case of a fault in the safety related parts of
the control system. For more information, see EN ISO13850:2008 or IEC60204-1:2006.
Category 1 stop: Robot motion is stopped with power available to the robot to achieve the stop and then
removal of power when the stop is achieved. It is a controlled stop, where the robot will continue along the
programmed path. Power is removed after one second or as soon as the robot stands still. For more
information, see EN ISO13850:2008 or IEC60204-1:2006.
Category 2 stop: A controlled stop with power left available to the robot. The robot can use up to one second
to stop all motion. The safety-related control system monitors that the robot stays at the stop position. For
more information, see IEC 60204-1:2006.
Diagnostic coverage (DC): is a measure of the effectiveness of the diagnostics implemented to achieve the
rated performance level. For more information, see EN ISO13849-1:2008.
Integrator: The integrator is the entity that designs the final robot installation. The integrator is responsible
for making the final risk assessment and must ensure that the final installation complies with local laws and
regulations.
MTTFd: The Mean time to dangerous failure (MTTFd) is a value based on calculations and tests used to
achieve the rated performance level. For more information, see EN ISO13849-1:2008.
Risk assessment: A risk assessment is the overall process of identifying all risks and reducing them to an
appropriate level. A risk assessment should be documented. Consult ISO 12100 for further information.
Performance Level: A Performance Level (PL) is a discrete level used to specify the ability of safety-related
parts of control systems to perform a safety functions under foreseeable conditions. PLd is the second highest
reliability classification, meaning that the safety function is extremely reliable. For more information, see
EN ISO13849-1:2008.
Maximum working radius: the distance from the center point of joint 1 to the center point of joint 6 when
the arm is in the zero position
