(2) Abnormality detection
This area of the screen indicates the score status obtained using the abnormality detection function.
The display also includes the status (normal, fault) of reduction gear, the status (normal, fault) of the
encoder, and the status (normal, warning, fault) of the battery.
You can check details of each joint axis on the Abnormality Detection screen.
(Refer to "7 Abnormality detection function".)
If " Warning " or "Fault" is indicated, check the content of the predictive maintenance message displayed
at the bottom of the screen and details of each part/each joint axis on the Abnormality Detection screen
and take measures.
For predictive maintenance message and measures, refer to "10. When consumption
occurred/abnormality detected, 10.2 Abnormality detection".
[Note] About abnormality detection
Abnormalities could be detected due to the following factors.
1) The setting of the detection level has no margin or the setting value is not appropriate.
2) Due to operating environment.
• The robot installation location or robot motion was changed.
• Effect of vibration around the robot or electric noise.
If the above factors are not considered as the cause, check the change in the score of the log on
the Abnormality Detection screen or the current status from the oscillograph.
(3) Predictive maintenance message
When the consumption status of the target part exceeds the notification day you specified, or the score
exceeds the detection level, the predictive maintenance message according to the status is displayed;
check the message content and take measures.
For predictive maintenance messages and measures, refer to "10. When consumption
occurred/abnormality detected".
(4) Save
"Save" button in the total score window exports all predictive maintenance data as a CSV file.
