Note. To perform a controller reset, execute a software reboot of the position board, or turn the power supply of the position board OFF
and ON again.
When position board SSCNET communication method is SSCNET and a factory default MR-J4(W )- B
servo amplifier is connected by SSCNET, the servo amplifier switches to J3 compatibility mode and the LED
displays "rST". In this state, executing a controller reset (software reboot, or turning the power supply of
position board OFF and ON again) and performing system startup procedure again enables all axes to be
connected.
When connecting by SSCNET from the next time onwards, a controller reset is not necessary. When a
controller reset cannot be executed, use the "MR-J4(W)-B mode selection" attached to MR Configurator2 to
manually switch the servo amplifier to J3 compatibility mode in advance.
For details on J3 compatibility mode, also refer to the MR-J4(W )- B Instruction Manual.
POINT
Do not connect a factory default MR-J4(W )- B servo amplifier by SSCNET
reconnect afterwards. If SSCNET is disconnected once, system error E4
occurs and all axes go into a forced stop state.
