2.2 Overhaul (Parts Replacement)
CAUTION
■
Overhaul timing is based on an assumption that all joints are operated for equal
distance. If a particular joint has a high duty or high load, it is recommended to
overhaul all joints (as many as possible) before exceeding 20,000 operation hours
with the joint as a basis.
The parts for the Manipulator joints may cause accuracy decline or malfunction due to
deterioration of the Manipulator resulting from long term use. In order to use the
Manipulator for a long term, it is recommended to overhaul the parts (parts replacement).
The time between overhauls is 20,000 operation hours of the Manipulator as a rough
indication.
However, it may vary depending on usage condition and degree of the load (such as when
operated with the maximum motion speed and maximum acceleration / deceleration in
continuous operation) applied on the Manipulator.
For the EPSON RC+ 7.0 Ver. 7.2.x or later (firmware Ver.7.2.x.x or later), the
recommended replacement time for the parts subject to maintenance (motors, reduction
gear units, and timing belts) can be checked in the [Maintenance] dialog box of the
EPSON RC+ 7.0.
For details, refer to the following manual.
Robot Controller RC700 / RC700-A Maintenance 6. Alarm
Note:
The recommended replacement time for the maintenance parts is when it reaches the L10
life (time until 10% failure probability). In the [Maintenance] dialog box, the L10 life is
displayed as 100%.
