The Dynamic Brake At The Load Inertia Moment; Encoder Cable Flexing Life - Mitsubishi Electric MR-J2S-CP Instruction 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.

13.4 Encoder cable flexing life

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