3 Safety
Term Description
Axis range Range of each axis, in degrees or millimeters, within which it may move.
The axis range must be defined for each axis.
Stopping distance Stopping distance = reaction distance + braking distance
The stopping distance is part of the danger zone.
Workspace The manipulator is allowed to move within its workspace. The work-
space is derived from the individual axis ranges.
Operator
(User)
The user of the industrial robot can be the management, employer or
delegated person responsible for use of the industrial robot.
Danger zone The danger zone consists of the workspace and the stopping distances.
Service life The service life of a safety-relevant component begins at the time of
delivery of the component to the customer.
The service life is not affected by whether the component is used in a
robot controller or elsewhere or not, as safety-relevant components are
also subject to ageing during storage.
KCP The KCP (KUKA Control Panel) teach pendant has all the operator con-
trol and display functions required for operating and programming the
industrial robot.
The KCP variant for the KR C4 is called KUKA smartPAD. The general
term “KCP”, however, is generally used in this documentation.
CRR Controlled Robot Retraction
CRR is an operating mode only available when KUKA.SafeOperation or
KUKA.SafeRangeMonitoring is used. If the robot has violated a monitor-
ing function and been stopped by the safety controller, it can only be
moved out of the violated area in CRR mode.
Manipulator The robot arm and the associated electrical installations
Safety zone The safety zone is situated outside the danger zone.
Safe operational stop The safe operational stop is a standstill monitoring function. It does not
stop the robot motion, but monitors whether the robot axes are station-
ary. If these are moved during the safe operational stop, a safety stop
STOP 0 is triggered.
The safe operational stop can also be triggered externally.
When a safe operational stop is triggered, the robot controller sets an
output to the field bus. The output is set even if not all the axes were sta-
tionary at the time of triggering, thereby causing a safety stop STOP 0 to
be triggered.
Safety STOP 0 A stop that is triggered and executed by the safety controller. The safety
controller immediately switches off the drives and the power supply to
the brakes.
Note: This stop is called safety STOP 0 in this document.
Safety STOP 1 A stop that is triggered and monitored by the safety controller. The brak-
ing process is performed by the non-safety-oriented part of the robot
controller and monitored by the safety controller. As soon as the manip-
ulator is at a standstill, the safety controller switches off the drives and
the power supply to the brakes.
When a safety STOP 1 is triggered, the robot controller sets an output to
the field bus.
The safety STOP 1 can also be triggered externally.
Note: This stop is called safety STOP 1 in this document.
