2.1.3. Abnormality detection function
This function detects abnormalities or deterioration of robot reduction gear components early.
Before the robot exhibits behavior that is a sign of an abnormality, the function can detect reduction gear or
encoder abnormalities.
Without adding sensors or an analysis personal computer, the robot controller alone can detect
abnormalities in reduction gear or the encoder.
