2.7 About Overhaul
Robots which have been in operation for an extended period of time can suffer from wear and other forms of
deterioration. In regard to such robots, we define overhaul as an operation to replace parts running out of
specified service life or other parts which have been damaged, so that the robots may be put back in shape
for continued use. As a rule of thumb, it is recommended that overhaul be carried out before the total
amount of servo-on time reaches the specified time (24,000 hours for the robot arm and 36,000 hours for
the controller). However, the degree of the equipment's wear and deterioration presumably varies depend-
ing on their operating conditions. Especially for operation with high load and frequency, the maintenance
cycle may be shorter. For details on the part selection for replacement and the timing of overhaul, contact
your dealer.
