Robot Stopping Functions; Protective Stop And Emergency Stop - ABB IRC5 Safety Manual

3 Robot stopping functions

3.1 Protective stop and emergency stop

Robot stopping functions
The robot has an emergency stop function and at least one protective stop function.
These functions have provision for the connection of external emergency stops
and protective devices.
The emergency stop function is a complementary protective measure and shall
not be applied as a substitute for safeguarding measures or safety functions.
The stop categories can be re-configured as defined by standards EN ISO
10218-1:2011 and IEC 60204-1:2016.
Emergency stop and protective stop functions are activated through dedicated
safety inputs or safety protocols.
For example, an output from a safety rated presence sensing device output can
be connected to a safety input on the robot controller. This is to initiate a protective
stop of the robot.

Safety manual for robot - Manipulator and IRC5 or OmniCore controller
3HAC031045-001 Revision: Q
As defined in IEC 60204-1, stopping by immediate removal of
power to the machine actuators.
As defined in IEC 60204-1, a controlled stop with power avail-
able to the machine actuators to achieve the stop and then re-
moval of power when the stop is achieved.
As defined in IEC 60204-1, a controlled stop with power remain-
ing available to the machine actuators.
(Only available for certain manipulators with OmniCore, see
the product manual for the manipulator.)
