5 Safety
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 or not,
as safety-relevant components are also subject to aging during storage.
KUKA smartPAD see “smartPAD”
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 operation is carried out by the non-safety-oriented section of the
robot controller and monitored by the safety controller. As soon as the
manipulator has stopped, the safety controller deactivates the drives
and the power supply of 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.
Safety STOP 2 A stop that is triggered and monitored by the safety controller. The brak-
ing operation is carried out by the non-safety-oriented section of the
robot controller and monitored by the safety controller. The drives
remain activated and the brakes released. As soon as the manipulator is
at a standstill, a safe operational stop is triggered.
When a safety STOP 2 is triggered, the robot controller sets an output to
the field bus.
The safety STOP 2 can also be triggered externally.
Note: This stop is called safety STOP 2 in this document.
Safety options Generic term for options which make it possible to configure additional
safe monitoring functions in addition to the standard safety functions.
Example: SafeOperation
smartPAD Programming device for the robot controller
The smartPAD has all the operator control and display functions
required for operating and programming the industrial robot.
Stop category 0 The drives are deactivated immediately and the brakes are applied. The
manipulator and any external axes (optional) perform path-oriented
braking.
Note: This stop category is called STOP 0 in this document.
