Encoder Cable Flexing Life - Mitsubishi Electric MELSERVO MR-J2S- A Instruction Manual

12. CHARACTERISTICS
Use the dynamic brake at the load inertia moment 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.
Note. The value assumes that the external dynamic brake is used.

12.4 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.
