Sharing the
Emergency Stop
with other
machines
You can set up a shared emergency stop function between the robot and other
machines by configuring the following I/O functions via the GUI. The Robot Emergency
Stop Input cannot be used for sharing purposes. If more than two UR robots or other
machines need to be connected, a safety PLC must be used to control the emergency
stop signals.
•
Configurable input pair: External emergency stop.
•
Configurable output pair: System emergency stop.
The illustration below shows how two UR robots share their emergency stop functions.
In this example the configured I/Os used are CI0-CI1 and CO0-CO1.

Safeguard stop
with automatic
resume
This configuration is only intended for applications where the operator cannot go
through the door and close it behind him. The configurable I/O is used to setup a reset
button outside the door to reactivate robot motion. The robot resumes movement
automatically when the signal is re-established.
WARNING
Do not use this configuration if signal can be re-established from the
inside of the safety perimeter.

In this example a door switch is a
basic safeguard device where the
robot is stopped when the door is
opened.
In this example a safety mat is a safety device
where automatic resume is appropriate. This
example is also valid for a safety laser scanner.
