(2) Permissible load to motor inertia ratio 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 there is a possibility that the ratio 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 direct drive motor.
The value in the parenthesis shows the value at the rated speed of the direct drive motor.
