Mitsubishi Electric CR800-D Series - Consumption Degree Calculation Function; Information Confirmation; Check Method; Setting and Operation

Basic specifications 20
2.1.2. Consumption degree calculation function
This function calculates the consumption degree [%] of robot components based on the actual operating
status (motor speed, load status, and others), and calculates the period up to maintenance/inspection or
overhaul.
Consumption Degree [%] is calculated based on the recommended maintenance time of each part as 100
[%].
Beside consumption degree [%] of each robot component, 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) are calculated, respectively and are
displayed on the comprehensive evaluation screen.

*1: Of the maintenance parts (grease, timing belt), the Consumption Degree [%] and Up to Maintenance [h]
of the part (joint axis) having the least remaining time are used.
*2: Of the overhaul parts (reduction gear, bearing, ball screw, ball spline), the Consumption Degree [%] of
the part (joint axis) having the least up to maintenance time is used.
