4.2.4 Safety information
Safety information cannot be held against the KUKA Robot Group. Even if all 
safety instructions are followed, this is not a guarantee that the robot system 
will not cause personal injuries or material damage.
No modifications may be carried out to the robot system without the authori-
zation of the KUKA Robot Group. Additional components (tools, software, 
etc.), not supplied by KUKA Robot Group, may be integrated into the robot 
system. The user is liable for any damage these components may cause to the 
robot system.
Stop reaction Drives Brakes Software
Ramp-down 
braking 
(STOP 2)
Drives remain 
on.
Brakes 
remain open.
Normal ramp which is 
used for acceleration 
and deceleration.
Path-main-
taining brak-
ing 
(STOP 1)
Drives are 
switched off 
after 1 second 
hardware 
delay.
Brakes are 
applied after 
1 s at latest.
In this time the control-
ler brakes the robot on 
the path using a steep-
er stop ramp.
Path-oriented 
braking 
(STOP 0)
Drives are 
switched off 
immediately.
Brakes are 
applied imme-
diately.
The controller attempts 
to brake the robot on 
the path with the re-
maining energy. If the 
voltage is not suffi-
cient, the robot leaves 
the programmed path.
Short-circuit
