17.1 J3 compatibility mode
17.1.1 Outline of J3 compatibility mode
MR-J4W_-_B servo amplifiers and MR-J4-_B_(-RJ) servo amplifiers have two operation modes. "J4 mode"
is for using all functions with full performance and "J3 compatibility mode" is compatible with MR-J3-B series
for using the amplifiers as the conventional series.
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, 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 11.7.)
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.
The J3 compatibility mode is not compatible with the master-slave operation
function.
