Instructions on storage

Precautions
Note the following when storing the rotary servo motor for an extended period of time (guideline: three or more months).
• Always store the linear servo motor indoors in a clean and dry place.
• When storing in a dusty and humid area, take measures such as covering the whole product.
• If the insulation resistance of the magnet wire decreases, reconsider how the equipment is being stored.
• Although the servo motor has been given rust prevention treatment with paint and preventive oil before shipment, rust may
still appear depending on the storage period and conditions. 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 and other parts.
• Before using the product after an extended storage, hand-turn the rotary servo motor output shaft and check to ensure that
there is no abnormality. For the rotary servo motor 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.
