(6) Maintenance, inspection and parts replacement
With age, the electrolytic capacitor of the servo amplifier will deteriorate. To prevent a secondary accident
due to a fault, it is recommended to replace the electrolytic capacitor every 10 years when used in general
environment.
Please consult our sales representative.
(7) Storage
Note the following points when storing the servo motor for an extended period of time (guideline: three or
more months).
Always store the servo motor indoors in a clean and dry place.
If it is stored in a dusty or damp place, make adequate provision, e.g. cover the whole product.
If the insulation resistance of the winding decreases, reexamine the storage method.
Though the servo motor is rust-proofed before shipment using paint or rust prevention oil, rust may be
produced depending on the storage conditions or storage period.
If the servo motor is to be stored for longer than six months, apply rust prevention oil again especially to
the machined surfaces of the shaft, etc.
Before using the product after storage for an extended period of time, hand-turn the motor output shaft to
confirm that nothing is wrong with the servo motor. (When the servo motor is equipped with a brake,
make the above check after releasing the brake with the brake power supply.)
When the equipment has been stored for an extended period of time, consult Mitsubishi.
