(1) Consumption degree
This area of the screen indicates the consumption degree of each part of the target axis and each joint axis
in a graph and numeric value [%].
(For target axis, refer to "2.1.4 Target models/target axes".)
(2) Predictive maintenance message
This field displays predictive maintenance messages according to the part status.
When the remaining time exceeds the notification day, an appropriate predictive maintenance message is
displayed; check the message content and take measures. For predictive maintenance message and
measures, refer to "10. When consumption occurred/abnormality detected 10.1 Consumption Degree ".
(3) Output CSV
Exports data of the consumption degree displayed in the window as a CSV file.
Storage destination and the file name of the CSV file
Storage destination：[Folder for workspace]¥[Project name]¥Maintenance¥PMLog
File name：[ConsumptionDataYYYYMMDD-HHMMSS].csv
(The storage destination and the folder name can be changed.)
Caution
[About calculation of the consumption degree]
• The consumption degree of each part is calculated on the assumption that the
robot is used in the environment (ambient temperature, humidity) within the
specification scope described in the instruction manual (standard
specifications).
• The consumption degree of each part is used as a reference value for
supporting the maintenance and inspection schedule calculated based on the
robot operating status. It does not guarantee the service life of the robot.
• Irrespective of the consumption degree, carry out daily inspection and periodic
maintenance and inspection described in the instruction manual (Standard
Specifications Manual, Robot Arm Setup & Maintenance).
• When the servo ON time exceeds the specified time (24,000 hours) or the
consumption degree exceeds the warning remaining number of days, we
recommend you perform overhaul of the robot arm.
• Reset operation of the consumption degree of each part must not be executed
except during maintenance or part replacement.
• For the total score of maintenance parts and overhaul parts, the value of the
part among all joint axes having the least remaining time (Up to Maintenance)
to the recommended maintenance time is output, respectively. For that reason,
the consumption degree of the total score could be smaller than the maximum
consumption degree value of each part.
• The remaining time is a reference value calculated based on the operating
status of the robot from the previous maintenance time. Also, the remaining
time is when you use the robot in the same way as before.
Therefore, if operation is changed, the remaining time may increase or
decrease.
・For the axis with multiple parts of one type, the part that wears the fastest in
terms of design is the subject for the calculation. It is recommended to perform
maintenance on the peripheral parts at the same time as the part replacement.
