1.3.1 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.
