17.1.2 Operation modes supported by J3 compatibility mode
The J3 compatibility mode supports the following operation modes.
Operation mode in J3 compatibility mode Model of MR-J3-_B Model of MR-J3-_BS Model of MR-J3W-_B
MR-J3-B standard control mode (rotary servo motor) MR-J3-_B MR-J3-_BS MR-J3W-_B
MR-J3-B fully closed loop control mode MR-J3-_B-RJ006 MR-J3-_BS
MR-J3-B linear control mode MR-J3-_B-RJ004 MR-J3W-_B
MR-J3-B DD motor control mode MR-J3-_B-RJ080W MR-J3W-_B
Each operation mode has the same ordering as conventional MR-J3-B series servo amplifiers and is
compatible with their settings.
In addition, the control response characteristic in the J3 compatibility mode will be the same as that of MR-J3
series.
17.1.3 J3 compatibility mode supported function list
The following shows functions which compatible with J4 mode and J3 compatibility mode. The letters such
as "A0" described after and mean servo amplifier software versions which compatible with each
function. Each function is used with servo amplifiers with these software versions or later.
