(2) Load to motor inertia moment ratio when using the dynamic brake
Use the dynamic brake under the load to motor inertia moment ratio indicated in the following table. If the
load to motor inertia moment is higher than this value, the dynamic brake may burn. If there is a possibility
that the load to motor inertia moment 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.
