Note 1. When the power supply voltage drops, the output and the rated speed cannot be guaranteed.
2. If the load to motor inertia moment ratio exceeds the indicated value, please contact your local sales office.
3. The above values are in the reduction gear input shaft.
4. Except for the shaft-through portion.
5. In the environment where the servo motor is exposed to oil mist, oil and/or water, a standard specification servo motor may not
be usable. Contact your local sales office.
