The Dynamic Brake At The Load Inertia Moment - Mitsubishi Electric MELSERVO-J3 Series Manual

13 CHARACTERISTICS

13.3.2 The dynamic brake at the load inertia moment

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 built-in dynamic brake may burn. If there is a possibility that the load
inertia moment may exceed the value, contact Mitsubishi.
The values of the load inertia moment ratio in the table are the values at the maximum rotation speed of the
servo motor.
