Part 4: Replacement of MR-J3W-_B with MR-J4W2-_B
(3) Gradual replacement of MR-J3W-_B with MR-J4W2-_B

Note 1. J3 series servo motor driving with MR-J4W2-_B servo amplifiers (J3 compatibility mode) will be sequentially available. For the
target models, schedule, etc., contact your local sales office.
2. The application software is available with MR Configurator2 version 1.12N or later.
POINT
MR-J3W-_B cannot drive an HG motor. When the servo motor is replaced with
an HG motor, simultaneous replacement with MR-J4W2-_B and HG motor is
necessary.
J3 series servo motor driving with MR-J4W2-_B servo amplifiers (J3 compatibility
mode) will be sequentially available. For the target models, schedule, etc.,
contact your local sales office.
When an "HC-_P motor" shown below is used, "simultaneous replacement with
MR-J4W2-_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 6:
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.
