Notes: 1. Contact your local sales office if the load to motor inertia ratio exceeds the value in the table. 2. The shaft-through portion is excluded. Refer to the asterisk 7 of "Annotations for Rotary Servo Motor Specifications" on p. 2-39 in this catalog for the shaft-through portion. 3. When unbalanced torque is generated, such as in a vertical lift machine, keep the unbalanced torque of the machine under 70% of the servo motor rated torque. 4. Refer to "Servo Motor Instruction Manual (Vol. 3)" for the restrictions when using the servo motors at altitude exceeding 1000 m and up to 2000 m above sea level. Refer to "Annotations for Rotary Servo Motor Specifications" on p. 2-39 in this catalog for the asterisks 1 to 6.
