Permissible Load To Motor Inertia When The Dynamic Brake Is Used - Mitsubishi MR-JE-10A Instruction Manual

10. CHARACTERISTICS
(2) Dynamic brake time constant
The following shows necessary dynamic brake time constant τ for equation 10.2.

10.3.2 Permissible load to motor inertia when the dynamic brake is used

Use the dynamic brake under the load to motor inertia ratio indicated in the following table. If the ratio is
higher than this value, the dynamic brake may burn. If there is a possibility that the ratio may exceed the
value, contact your local sales office.
The values of the permissible load to motor inertia ratio in the table are the values at the maximum rotation
speed of the servo motor.
