Note 1) 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.
