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. This value is applicable when the external regenerative resistors, GRZG400-_Ω (standard accessory) are used with cooling fans (two units of 92 mm 5 92 mm, minimum airflow: 1.0 m 3 /min). Note that [Pr. PA02] must be changed. 5. 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. 6. This value is applicable when the servo motor is combined with MR-J4-_GF(-RJ)/MR-J4-_B(-RJ)/MR-J4-_A(-RJ) servo amplifier. Contact your local sales office for the regenerative braking frequency with MR-J4-DU_B(-RJ)/MR-J4-DU_A(-RJ) drive unit. Refer to "Annotations for Rotary Servo Motor Specifications" on p. 2-39 in this catalog for the asterisks 1 to 6.
