17.1 J3 compatibility mode

17.1.1 Outline of J3 compatibility mode
MR-J4W_-_B servo amplifiers and MR-J4-_B servo amplifiers have two operation mode: "J4 mode" is for
using all functions with full performance and "J3 compatibility mode" for using the conventional MR-J3-B
servo amplifiers.
When you connect an amplifier with SSCNET III/H communication for the first controller communication by
factory setting, the operation mode will be fixed to "J4 mode". For SSCNET communication, it will be fixed to
"J3 compatibility mode". When you set the mode back to the factory setting or change the mode, use the
application "MR-J4(W)-B mode selection".
The application "MR-J4(W)-B mode selection" is packed with MR Configurator2 of software version 1.12N or
later.
For the operating conditions of the application "MR-J4(W)-B mode selection", use MR Configurator2. (Refer
to section 11.4.)
17.1.2 Operation modes supported by J3 compatibility mode
The J3 compatibility mode supports the following operation modes.
Operation mode in J3 compatibility mode
MR-J3-B standard control mode (rotary servo motor)
MR-J3-B fully closed loop control mode
MR-J3-B linear servo motor control mode
MR-J3-B DD motor control mode
Each operation mode has the same ordering as conventional MR-J3-B series servo amplifiers and is
compatible with their settings.
In addition, the control response characteristic in the J3 compatibility mode will be the same as that of MR-J3
series.
POINT
The J3 compatibility mode is compatible only with HG series servo motors.
The fully closed loop control in the J3 compatibility mode is available for the
servo amplifiers with software version A3 or later.
Specifications of the J3 compatibility mode of the servo amplifier with software
version A4 or earlier differ from those with software version A5 or later. Refer to
section 17.1.8.
The J3 compatibility mode is not compatible with the master-slave operation
function.
