Description
Communication between the axis computer and the serial measurement circuit board is interrupted on measurement link arg in drive module arg.
Consequences
The system enters a "System Failure" state and loses calibration messages.
Possible causes
This may be caused by poor contact or poor wiring (shielding), especially if non-ABB cables are used on the additional axis. Another possible cause is a faulty serial measurement circuit board or axis computer.
Recommended actions
- Reset the robot's revolution counter as described in the robot's product manual.
- Ensure that the wiring between the serial measurement circuit board and the axis computer is properly connected and that the wiring meets the specifications specified in ABB.
- Make sure the line shields are properly connected to both ends.
- Make sure there is no strong electromagnetic interference in the area close to the robot's lines.
- Make sure the serial measurement circuit board and axis computer are working completely properly. Replace any faulty parts.
