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.
