Consumption Degree Calculation Function - Mitsubishi Electric CR800-D Series User Manual

6. 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.
The screen indicates the consumption degree of each joint axis of maintenance parts and overhaul parts
calculated by the consumption degree calculation function.
The current status of maintenance parts (grease, timing belt) and overhaul parts (reduction gear, bearing,
ball screw/ball spline) is displayed, separately in two screens. Also, the current status is displayed as the
preventive maintenance message.
