CAUTION
Disturbing signals with levels higher than those defined in the specific
IEC standards can cause unexpected behaviors from the robot. Be
aware of the following:
•
The robot has been tested according to international IEC
standards for ElectroMagnetic Compatibility (EMC). Very
high signal levels or excessive exposure can damage the robot
permanently. EMC problems are found to happen usually in
welding processes and are normally prompted by error
messages in the log. Universal Robots cannot be held
responsible for any damages caused by EMC problems.
•
I/O cables going from the Control Box to other machinery and
factory equipment may not be longer than 30m, unless
additional tests are performed.
GROUND
Negative connections are referred to as Ground (GND) and are
connected to the casing of the robot and the Control Box. All
mentioned GND connections are only for powering and signalling. For
PE (Protective Earth) use the M6-size screw connections marked with
earth symbols inside the Control Box. The grounding conductor shall
have at least the current rating of the highest current in the system.
READ MANUAL
Some I/Os inside the Control Box can be configured for either normal
or safety-related I/O. Read and understand the complete Electrical
Interface chapter.
