Part 4: Replacement of MR-J3W-_B with MR-J4W2-_B
4 - 4
(3) Gradual replacement of MR-J3W-_B with MR-J4W2-_B
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.
Replacing the system, you can drive some J3 series servo motors with MR-
J4W2-_B (J4 mode) and MR-J4W2-_B(J3 compatibility mode). Refer to "Part 6
Common Reference Material" for the applicable motor.
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 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.

The MR-J4W2-_B series
has the J3 compatibility
mode (Note 1). The MR-
J4W2-_B series and the
MR-J3W-_B series can be
used together.
Optical fiber cables for the
conventional SSCNETIII
can be used as they are.
Change the settings of the
MR-J4W2-_B to J4 mode
using the application
software "MR-J4(W)-B
mode selection" (Note 2).
The servo amplifiers and
servo motors can be used
as they are.
Note 1. Replacing the system, you can drive some J3 series servo motors with MR-J4W2-_B (J4 mode) and MR-J4W2-_B (J3
compatibility mode). Refer to "Part 6 Common Reference Material" for the applicable motor.
2. The application software is available with MR Configurator2 version 1.12N or later.
