12. SERVO MOTOR
Note 1. When the power supply voltage drops, the output and the rated speed cannot be guaranteed.
2. If the load to motor inertia ratio exceeds the indicated value, contact your local sales office.
3. The value on the gear reducer input axis.
4. Except for the shaft-through portion. IP classifies the degrees of protection provided against the intrusion of solid objects and
water in electrical enclosures.
5. In the environment where the servo motor is exposed to oil mist, oil, or water, the servo motor of the standard specifications may
not be usable. Please contact your local sales office.
6. The servo motor alone. The following figure shows the vibration directions. The value is the one at the part that indicates the
maximum value (normally the opposite to load-side bracket). When the servo motor stops, fretting is likely to occur at the
bearing. Therefore, suppress the vibration to about half of the permissible value. Note that this does not apply to the geared
servo motor.
