When any alarm has occurred, eliminate its cause, ensure safety, and deactivate the alarm before
restarting operation.
Provide an adequate protection to prevent unexpected restart after an instantaneous power failure.
(6) Storage
CAUTION
Note the followings 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, check how to store the equipment.
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 servo motor output
shaft to confirm that nothing is wrong with the servo motor. When the servo motor is equipped with an
electromagnetic brake, check it after releasing the electromagnetic brake with the brake power supply.
When the product has been stored for an extended period of time, contact your local sales office.
