17.1.4 How to switch J4 mode/J3 compatibility mode
There are two ways to switch the J4 mode/J3 compatibility mode with the MR-J4W_-_B servo amplifier and
MR-J4-_B_(-RJ) servo amplifier.
(1) Mode selection by the automatic identification of the servo amplifier
J4 mode/J3 compatibility mode is identified automatically depending on the connected controller.
When the controller makes a connection request with SSCNET III/H communication, the mode will be
"J4 mode". For SSCNET communication, it will be "J3 compatibility mode".
For the J3 compatibility mode, standard control, linear servo motor control, or direct drive motor control
will be identified automatically with a motor (encoder) connected to the servo amplifier. For the J4 mode,
the operation mode will be the setting of [Pr. PA01].

(2) Mode selection using the application "MR-J4(W)-B mode selection" or "MR Mode Change"
You can set the factory setting, J4 mode/J3 compatibility mode, and operation mode with the dedicated
application.

17.1.5 How to use the J3 compatibility mode
(1) Setting of the controller
To use in the J3 compatibility mode, select MR-J3 series in the system setting window.
Operation mode in J3 compatibility mode System setting
MR-J3-B standard control mode (rotary servo motor) Select MR-J3-_B.
MR-J3-B fully closed loop control mode Select MR-J3-_B fully closed.
MR-J3-B linear servo motor control mode Select MR-J3-_B linear.
MR-J3-B DD motor control mode Select MR-J3-_B DD motor.
(2) Setting of MR Configurator
To use in the J3 compatibility mode, make the system setting as follows.
Operation mode in J3 compatibility mode System setting
MR-J3-B standard control mode (rotary servo motor) Select MR-J3-_B.
MR-J3-B fully closed loop control mode Select MR-J3-_B fully closed.
MR-J3-B linear servo motor control mode Select MR-J3-_B linear.
MR-J3-B DD motor control mode Select MR-J3-_B DD motor.
Cautions for using MR Configurator
The gain search cannot be used. You can use the advanced gain search.
The C-axis of MR-J4W3-_B cannot be set with MR Configurator. Use MR Configurator2 for it.
