5.2 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. (When operated with the maximum motion speed and
maximum acceleration / deceleration in continuous operation) However, it may
vary depending on usage condition and the load applied on the Manipulator.
For the EPSON RC+ 7.0 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.
For details, refer to the following manual.
T series Manipulator Manual: Maintenance 4. Alarm
VT series Manipulator Manual: Maintenance 4. 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%.
