6.1.5 How to switch J4 mode/J3 compatibility mode
There are two ways to switch the J4 mode/J3 compatibility mode with the MR-J4-_B_(-RJ) servo amplifier
and MR-J4W2-_B 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 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].
