Refer to section 11.8
CN3
The frames of the CN2 and CN3
connectors are connected to the
protective earth terminal in the
servo amplifier.

Connector Name Description
CN1A
Connector for SSCNET III cable for
previous servo amplifier axis
Used for connection with the controller or previous axis servo amplifier.
CN1B
Connector for SSCNET III cable for
next servo amplifier axis
Used for connection with the next axis servo amplifier or for connection of the cap.
CN2 Connector for encoder Used to connect the servo motor encoder.
CN4 Connector for encoder battery
When using it as absolute position detection system, connect to battery (MR-
BAT6V1SET). Before mounting a battery, turn off the main circuit power and wait for
15 minutes or longer until the charge lamp turns off. Then, check the voltage
between P+ and N- with a voltage tester or others. Otherwise, an electric shock may
occur. In addition, when confirming whether the charge lamp is off or not, always
confirm it from the front of the servo amplifier. Replace the battery with main circuit
power-off and with control circuit power-on. Replacing the battery with the control
circuit power-off results in loosing absolute position data.
CN5 USB connector The personal computer is connected.
CN8 STO I/O signal connector For the STO I/O signal connector (CN8), refer to chapter 13.
