7 Troubleshooting
7.1 Introduction to troubleshooting
Introduction
The product manual and the circuit diagram contains information that can be good
when troubleshooting.
For OmniCore, all event logs from the software can be seen on the FlexPendant,
or in
Technical reference manual - Event logs for RobotWare 7 .
Make sure to read through the section Safety on page 15 before starting.
Troubleshooting strategies
1 Isolate the fault to pinpoint the cause of the problem from consequential
problems.
2 Divide the fault chain in two.
3 Check communication parameters and cables.
4 Check that the software version is compatible with the hardware.
Work systematically
1 Take a look around to make sure that all screws, connectors, and cables are
secured, and that the robot and other parts are clean, not damaged, and
correctly fitted.
2 Replace one thing at a time.
3 Do not replace units randomly.
4 Make sure that there are no loose screws, turnings, or other unexpected
parts remaining after work has been performed.
5 When the work is completed, verify that the safety functions are working as
intended.
Keep a track of history
• Make a historical fault log to keep track of problems over time.
• Consult those working with the robot when the problem occurred.
Basic scenarios
What to look for during troubleshooting depends on when the fault occurred. Was
the robot recently installed or was it recently repaired? The following table gives
hints on what to look for in specific situations.
Check:
• the configuration files
• connectors
• options and their configuration
• changes in the robot working space/movements.
The robot has recently
been installed
