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 8 of "Annotations for Servo Motor Specifications" in the 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. When the servo motor decelerates to a stop from the rated speed, the regenerative frequency will not be limited. When the servo motor decelerates to a stop from the maximum speed, the regenerative frequency will not be limited if the load to motor inertia ratio is 11 times or less.

5. When the servo motor decelerates to a stop from the rated speed, the regenerative frequency will not be limited if the load to motor inertia ratio is 9 times or less. When the servo motor decelerates to a stop from the maximum speed, the regenerative frequency will not be limited if the load to motor inertia ratio is 3 times or less.

6. The value in brackets is applicable with parameter setting. Refer to "MR-JE-_C Servo Amplifier Instruction Manual" for details.

7. When absolute position detection system is used, absolute position data is read with the Ethernet communication. Refer to "MR-JE-_C Servo Amplifier Instruction Manual" for details.

8. Refer to "HG-KN HG-SN Servo Motor Instruction Manual" 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 Servo Motor Specifications" in the catalog for the asterisks 1 to 7.
