10.3.2 The dynamic brake at the load inertia moment
Use the dynamic brake under the load inertia moment ratio indicat ed 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.
