Permissible Load To Motor Inertia When The Dynamic Brake Is Used - Mitsubishi MR-J4-10A 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 the load to motor inertia ratio exceeds the
indicated 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.

Note 1. The permissible load to motor inertia ratio is 15 at the rated rotation speed.
2. The permissible load to motor inertia ratio is 30 at the rated rotation speed.

Note. When the maximum torque is increased to 400%, the permissible load to motor inertia ratio at the maximum speed
of the servo motor is 25 times.
