6-5 Periodic Maintenance
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. Periodic inspection and part replacement
are necessary to ensure proper long-term operation of Servomotors and Servo Drivers.
The periodic maintenance cycle depends on the installation environment and application conditions of
the Servomotor or Servo Driver. Recommended maintenance times are listed below for Servomotors
and Servo Drivers. Use these for reference in determining actual maintenance schedules.
Resume operation only after transferring all data required for operation
to the new Unit. Not doing so may result in an unexpected operation.
Do not attempt to disassemble, repair, or modify any Units. Any attempt
to do so may result in malfunction, fire, or electric shock.
6-5-1 Servomotor Maintenance
The recommended periodic maintenance schedule is listed below.
•
Bearings: 20,000 hours
•
Decelerator: 20,000 hours
These values presume an ambient Servomotor operating temperature of 40°C, shaft
loads within the allowable range, rated operation (rated torque and rated r/min), and
proper installation as described in the
Operation 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 settings 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.
•
When requesting repairs or investigations, separate the Servomotors and
Decelerators, and make separate requests for each product.
