Periodic Maintenance
Maintenance and Inspection Precautions
WARNING
Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so may
result in malfunction, fire, or electric shock.
Caution
Resume operation only after transferring to the new Unit the contents of the data
required for operation. Not doing so may result in an unexpected operation.
Servomotors and Servo Drivers contain many components and will operate properly
only when each of the individual components is operating properly. Some of the electri-
cal and mechanical components require maintenance depending on application condi-
tions. In order to ensure proper long-term operation of Servomotors and Drivers, period-
ic inspection and part replacement is required according to the life of the components.
The periodic maintenance cycle depends on the installation environment and application conditions of
the Servomotor or Driver. Recommended maintenance times are listed below for Servomotors and
Drivers. Use these for reference in determining actual maintenance schedules.
H
Servomotors
•
Recommended Periodic Maintenance
Bearings:
20,000 hours
Reduction gear:
20,000 hours
Oil seal:
5,000 hours
Application Conditions: Ambient Servomotor operating temperature of 40
_
C, within allowable shaft
load, rated operation (rated torque and r/m), installed as described in opera-
tion manual.
•
The radial loads during operation (rotation) on timing pulleys and other components contacting belts is
twice the still load. Consult with the belt and pulley manufacturers and adjust designs and system set-
tings so that the allowable shaft load is not exceeded even during operation. If a Servomotor is used
under a shaft load exceeding the allowable limit, the Servomotor shaft can break, the bearings can
burn out, and other problems can occur.
H
Servo Drivers
•
Recommended Periodic Maintenance
Aluminum analytical capacitors: 50,000 hours, at an ambient Servo Driver operating temperature
of 40
_
C, rated operation (rated torque), installed as described in
operation manual.
Axle fan: 30,000 hours, at an ambient Servo Driver operating temperature of 40
_
C and an ambi-
ent humidity of 65%.
Absolute encoder backup battery:
50,000 hours, at an ambient Servo Driver operating temperature of 20
_
C.
