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.
3. The value in brackets is applicable when the torque is increased with a combination with a larger-capacity servo amplifier.
4. The continuous running duty and the speed are not guaranteed when the power supply voltage is dropped.
5. 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.
6. For the HK-KT053W with an oil seal, use 80 % of the rated output.
7. When IP67 cables are required, please contact Mitsubishi Electric System & Service Co., Ltd. OVERSEAS SERVICE SECTION. (Email: osb.webmaster@ melsc.jp)
8. 28 times or less for 6000 r/min or less.
9. When the servo motor is combined with a 100 W servo amplifier, the recommended load to motor inertia ratio is for operating the servo motor at the rated speed.If operating the servo motor at a speed exceeding the rated speed, check the need for a regenerative option with the drive system sizing software Motorizer. A servo amplifier with a larger capacity can be combined.

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.
3. The value in brackets is applicable when the torque is increased with a combination with a larger-capacity servo amplifier.
4. The continuous running duty and the speed are not guaranteed when the power supply voltage is dropped.
5. 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.

1. The electromagnetic brake is for holding. It cannot be used for deceleration applications.
2. Brake gap is not adjustable. Electromagnetic brake life is defined as the time period until readjustment is needed.
