(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 ".)

time is displayed.
Consumption degree [%]
The remaining time of each joint axis is individually
calculated and the consumption degree [%] of the part
(joint axis) having the least remaining time is used.
