2.2 Overhaul (Parts Replacement)
■ If you do not overhaul properly, it may have a serious impact on safety.
■ 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
CAUTION
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.
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.
