Connector Name
Function/application
CN1A
Connector for SSCNET cable for
previous servo amplifier axis
Used for connection with the controller or previous axis servo amplifier.
CN1B
Connector for SSCNET cable for
next servo amplifier axis
Used for connection with the next axis servo amplifier or for connection of the cap.
CN2A
Connector for A-axis encoder
Connect with the A-axis servo motor encoder.
CN2B
Connector for B-axis encoder
Connect with the B-axis servo motor encoder.
CN3
I/O signal connector
Used to connect I/O signals.
CN4 Battery
connector
When using it as absolute position detection system, connect to battery. Before
connecting battery, turn off the main circuit power supply and check that the charge lamp
turns off. 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
Communication connector (USB)
The personal computer is connected.
