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
electrical and mechanical components require maintenance depending on application
conditions. In order to ensure proper long-term operation of Servomotors and Drivers,
periodic 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.
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
• 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 settings so that the allowable shaft load is not exceeded even during operation. If a Servo-
motor 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.
Servo Drivers
■
• Recommended Periodic Maintenance
Aluminum analytical capacitors: 50,000 hours, at an ambient Servo Driver operating temperature
Axle fan: 30,000 hours, at an ambient Servo Driver operating temperature of 40 ° C and an ambient
humidity of 65%.
