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 ratio is higher than this value,
the dynamic brake may burn. If the ratio exceeds 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 speed of the servo motor.
