(2) The dynamic brake at the load inertia mom ent
Use the dynamic brake under the load inertia moment ratio indicated in the following table. If the load inertia
moment is higher than this value, the ext ernal dynamic brake may burn. If there is a poss ibility that the load
inertia moment may exceed the value, contac t Mitsubishi.
The values of the load inertia moment rat io in the table are the values at the maxim um rotation speed of the
servo motor.
