How To Utilize The Predictive Maintenance Function - Mitsubishi Electric CR800-D Series User Manual

2.2. How to utilize the predictive maintenance function

The predictive maintenance function assumes the following usages.
(1) At system startup
It is possible to estimate the replacement time of maintenance parts or the recommended maintenance
time of overhaul parts when an operation pattern of the robot is repeated using "Maintenance Simulation".
This function can be used for planning a maintenance schedule when starting up a system.
(For details, refer to "9 Maintenance simulation".)
(2) System operation time (at periodic inspection)
You can check the consumption degree using the "Consumption degree calculation function" or the
existence of abnormalities using the "Abnormality detection function".
Because the consumption degree calculation function calculates the consumption degree based on the
actual robot operation status (motor speed, loads, and others), you can check the current robot
consumption degree and remaining time to replacement/maintenance.
This function is useful for reviewing or planning a maintenance schedule.
(For function details, refer to "6 Consumption degree calculation function", "7 Abnormality detection
function".)
(3) System operation time (when a part is consumed)
As a result of the remaining time to replacement/maintenance calculated by the consumption degree
calculation function, if the set remaining time is reached, that effect is notified by the method you set.
Check detailed information and arrange or carry out maintenance.
By carrying out appropriate maintenance, it is possible to prevent the production line from stopping due
to a sudden failure of the robot and reduce down time.
(For details, refer to "6 Consumption degree calculation function".)
(4) System operation time (when an abnormality is detected)
When an abnormality of the robot is detected (the score exceeds the set detection level), that effect is
notified by the method you set. Check detailed information and carry out maintenance such as part
replacement.
Doing so could prevent the production line from stopping due to a sudden failure of the robot and reduce
down time.
(For function details, refer to "7 Abnormality detection function".)
