Part 3: Review on Replacement of MR-J3-_B_ with MR-J4-_B_
3 - 4
POINT
MR-J3-_B_ cannot drive an HG motor. When the servo motor is replaced with
an HG motor, simultaneous replacement with MR-J4-_B_ and an HG motor is
necessary.
When an "HC-_P motor" shown below is used, "simultaneous replacement with
MR-J4-_B_ and an HG motor" is recommended. 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 7: Replacement of
Motor".)
The low inertia "HG-JR motor" is recommended for the replacement of "HC-LP
motor".
To use a servo motor other than the motors listed in following table, check the
compatibility with the equipment because the motor inertia, etc. is different.

Note 1. The MR-J4-_B_ series has "J3 compatibility mode". MR-J4-_B_ and MR-J3-_B_ servo amplifiers can be used together. Optical
fiber cables for the conventional SSCNET III can be used as they are.
2. Change the settings of the MR-J4-_B_ servo amplifier to "J4 mode" using the application software "MR-J4(W)-B mode
selection" (*1). The servo amplifiers and servo motors can be used as they are.
(*1): The application software is available with MR Configurator2 version 1.12 or later.
