13.3.2 The dynamic brake at the load inertia moment
Use the dynamic brake under the load inertia moment ratio indicate d in the following table. If the load inertia
moment is higher than this value, the built-in dynam ic brake may burn. If there is a possibility that the load
inertia moment may exceed the value, contac t Mitsubishi.
The values of the load inertia moment ratio in the table are the values at the maximum rotation speed of the
servo motor.
