(3) Setting of MR Configurator2
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 control mode Select MR-J3-_B linear.
MR-J3-B DD motor control mode Select MR-J3-_B DDM.
Cautions for using MR Configurator2
Use MR Configurator2 with software version 1.12N or later. Older version than 1.12N cannot be used.
Information about existing models (MR-J3) cannot be updated with the parameter setting range update
function. Register a new model to use.
The alarm will be displayed by 3 digits.
The robust disturbance compensation cannot be used.
17.1.6 Cautions for switching J4 mode/J3 compatibility mode
The J3 compatibility mode of the operation mode is automatically identified by factory setting depending on a
connected encoder. If a proper encoder is not connected at the first connection, the system will not start
normally due to a mismatch with a set mode with the controller. (For the J4 mode, you can set the operation
mode with [Pr. PA01].) For example, if the controller is connected without connecting a linear encoder at
linear servo motor driving, the servo amplifier will be the standard control mode (rotary servo motor). The
system will not start because the controller is connected with the linear servo motor driving amplifier.
When the operation mode mismatches, the servo amplifier will display [AL. 3E.1 Operation mode error]. Set
the mode back to the factory setting or set correctly (J4 mode/J3 compatibility mode and operation mode)
using the application "MR-J4(W)-B mode selection".
17.1.7 Cautions for the J3 compatibility mode
The J3 compatibility mode are partly changed and has restrictions compared with MR-J3 series.
(1) The alarm display was changed from 2 digits (_ _) to 3 digits (_ _. _). The alarm detail number (._) is
displayed in addition to the alarm No (_ _). The alarm No. (_ _) is not changed.
(2) When the power of the servo amplifier is cut or fiber-optic cable is disconnected, the same type
communication can be cut regardless of connection order. When you power on/off the servo amplifier
during operation, use the connect/disconnect function of the controller. Refer to the following manuals
for detail.
