5 Safety
The safeguards (e.g. safety gate) must be situated inside the safety zone. In
the case of a stop, the manipulator and external axes (optional) are braked
and come to a stop within the danger zone.
The danger zone consists of the workspace and the stopping distances of the
manipulator and external axes (optional). It must be safeguarded by means of
physical safeguards to prevent danger to persons or the risk of material dam-
age.
5.4 Overview of protective equipment
The protective equipment of the mechanical component may include:

Mechanical end stops

Mechanical axis range limitation (optional)

Axis range monitoring (optional)

Release device (optional)

Labeling of danger areas
Not all equipment is relevant for every mechanical component.
5.4.1 Mechanical end stops
Depending on the robot variant, the axis ranges of the main and wrist axes of
the manipulator are partially limited by mechanical end stops.
Additional mechanical end stops can be installed on the external axes.
5.4.2 Mechanical axis range limitation (optional)
Some manipulators can be fitted with mechanical axis range limitation in axes
A1 to A3. The adjustable axis range limitation systems restrict the working
range to the required minimum. This increases personal safety and protection
of the system.
In the case of manipulators that are not designed to be fitted with mechanical
axis range limitation, the workspace must be laid out in such a way that there
is no danger to persons or material property, even in the absence of mechan-
ical axis range limitation.
If this is not possible, the workspace must be limited by means of photoelectric
barriers, photoelectric curtains or obstacles on the system side. There must be
no shearing or crushing hazards at the loading and transfer areas.
5.4.3 Axis range monitoring (optional)
Some manipulators can be fitted with dual-channel axis range monitoring sys-
tems in main axes A1 to A3. The positioner axes may be fitted with additional
axis range monitoring systems. The safety zone for an axis can be adjusted
If the manipulator or an external axis hits an obstruction
or a mechanical end stop or axis range limitation, the ma-
nipulator can no longer be operated safely. The manipulator must be taken
out of operation and KUKA Roboter GmbH must be consulted before it is put
back into operation .
This option is not available for all robot models. Information on spe-
cific robot models can be obtained from KUKA Roboter GmbH.
