Permissible Load To Motor Inertia When The Dynamic Brake Is Used - Mitsubishi Electric MR-J4W2-0303B6 Instruction Manual

10. CHARACTERISTICS

10.3.2 Permissible load to motor inertia when the dynamic brake is used

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