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.
