5. Total score
This screen displays the status of reduction gear, the encoder, and battery (normal, warning,
abnormalities), and the total evaluation result of the consumption degree calculation function.
(1) Consumption degree calculation
The Consumption Degree area indicates the total score (Consumption Degree [%] and Up to
Maintenance) of maintenance parts (grease, timing belt), and the total score (Consumption Degree [%])
of overhaul parts (reduction gear, bearing, ball screw, ball spline), and the accumulated servo ON time
since the previous overhaul time.
Consumption degree [%] is displayed based on the recommended maintenance time of each part as
100 [%].
You can check details of each part and joint axis on the Consumption Degree screen.
(Refer to "6 Consumption degree calculation function ".)
