Glossary
Stop category 0
Stopping is achieved by an immediate interruption in the power supply to the drive components. This
uncontrolled stopping can cause the robot to deviate from its programmed track. For more information
on this, see EN ISO 13850 or DIN EN 60204-1.
Stop category 1
Stopping is achieved through active braking, as the energy supply to the drive components is initially
maintained. Only after a successful stop is the power supply disconnected. This is a controlled stop, dur-
ing which the robot does not exit is programmed track. For more information on this, see EN ISO 13850
or DIN EN 60204-1.
Stop category 2
Stopping is achieved through active braking (controlled stopping), and after the stop, the energy supply
to the drive components is maintained. The safe control system monitors the stop. For more information
on this, see DIN EN 60204-1.
Performance Level
The Performance Level (PL) describes the capacity of safety-related parts of a control system to execute
safety-critical functions under predictable conditions. The required Performance Level is also used to
achieve the required risk minimization for individual safety functions. Therefore, the Performance Level
of safety-critical parts of a control system must be at least as high as the required Performance Level.
The Performa
nce Level “d” is the second highest reliability classification. For more information on this,
see DIN EN 13849-1.
