Analogue Outputs - Universal Robots UR5 with CB2 User Manual

2.4. Controller I/O
Signal Communication with other Machinery or PLCs
If communication with other machinery or PLCs is needed they must use pnp
technology. Remember to create a common GND connection between the
different interfaces. An example where two UR robots (A and B) are communi-
cating with each other is illustrated above.

2.4.3 Analogue Outputs

Valid output voltage in current mode
Valid output current in voltage mode
Short-circuit current in voltage mode
Output resistance in voltage mode
The analog outputs can be set for both current mode and voltage mode, in
the range of 4-20mA and 0-10V respectively.
To illustrate clearly how easy it is to use analog outputs, some simple exam-
ples are shown.
Using the Analog Outputs
This is the normal and best way to use analog outputs. The illustration shows
a setup where the robot controller controls an actuator like a conveyor belt.
The best result is accomplished when using current mode, because it is more
immune to disturbing signals.
