6.1.4 Distinguishing J3 compatibility mode
Following shows the status display of the servo amplifier axis of MR-J4-_B_ and MR-J4W2-_B. In the states
of "Waiting for servo system controller power to switch on (SSCNET III/H communication)" and "Servo
system controller power off", the decimal point on the first digit LED turns off in J4 mode, and blinks in J3
compatibility mode. This function can be used with servo amplifiers with software version A5 or later.
The segment of the last 2 digits shows the axis number.
