The Dynamic Brake At The Load Inertia Moment - Mitsubishi Electric MELSERVO-J3 Series Instruction Manual

13. CHARACTERISTICS

13.3.2 The dynamic brake at the load inertia moment

Use the dynamic brake under the load to motor inertia ratio indicated in the following table. If the ratio is higher
than this value, the dynamic brake may burn. If there is a possibility that the ratio may exceed the value,
contact your local sales office.
The values of the load inertia moment ratio in the table are the values at the maximum rotation speed of the
servo motor.

Note 1. The load inertia moment ratio is 15 at the rated rotation speed.
2. When the external dynamic brake is used.
3. The permissible load to motor inertia ratio is 30 at the rated rotation speed.
