(6) Storing of servo motor
CAUTION
Note the following points when storing the servo motor for an extended period of time (guideline: three or
more months).
Be sure to 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 servo motor that has been stored for an extended period of time, hand-turn the servo
motor output shaft to confirm that nothing is wrong with the servo motor. (For the servo motor with an
electromagnetic brake, turn ON the power supply of the electromagnetic brake, first. Then, release the
electromagnetic brake before hand-turn.)
When the equipment has been stored for an extended period of time, contact your local sales office.
(7) Maintenance, inspection and parts replacement
CAUTION
Make sure that the emergency stop circuit operates properly such that an operation can be stopped
immediately and a power is shut off by the emergency stop switch.
It is recommended that the servo amplifier be replaced every 10 years when it is used in general
environment.
(8) General instruction
