Part 3: Review on Replacement of MR-J2S-_B_ with MR-J4-_B_
POINT
If the existing system is any of the combinations in the following table, it is
recommended to replace both the servo amplifier and servo motor with an MR-
J4-_B_ and HG motor at the same time. When an HG motor is adopted, the
capacity of the servo amplifier needs to be changed. (Consider replacement,
referring to "torque characteristics" described in "Part 8: Replacement of
Motor".)
