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

10. CHARACTERISTICS

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.
10.4 Cable bending life
The bending life of the cables is shown below. This graph calculated values. Since they are not guaranteed
values, provide a little allowance for these values.
