Cautions For Switching J4 Mode/J3 Compatibility Mode - Mitsubishi Electric MR-J4-10B(-RJ) Instruction Manual

17. APPLICATION OF FUNCTIONS
(3) Setting of MR Configurator2
To use in the J3 compatibility mode, make the system setting as follows.
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".
