3.9 SSCNET III cable connection 
 
POINT 
 
Do not look directly at the light generated from the CN1A/CN1B connector of the 
servo amplifier or the end of the SSCNET III cable. The light can be a discomfort 
when it enters the eye. 
 
(1)  SSCNET III cable connection 
For the CN1A connector, connect the SSCNET III cable connected to a controller in host side or a servo 
amplifier of the previous axis. For the CN1B connector, connect the SSCNET III cable connected to the 
servo amplifier of the next axis. For the CN1B connector of the final axis, put a cap came with the servo 
amplifier.

(2)  How to connect/disconnect cable 
 
POINT 
 
The CN1A and CN1B connectors are capped to protect light devices inside the 
connector from dust. For this reason, do not remove the cap until just before 
connecting the SSCNET III cable. Then, when removing the SSCNET III cable, 
make sure to put a cap. 
Keep the cap for the CN1A/CN1B connector and the tube for protecting the 
optical cord end of an SSCNET III cable in a plastic bag with a slide fastener of 
the SSCNET III cable to prevent them from becoming dirty. 
When asking repair of the servo amplifier for some malfunctions, make sure to 
cap the CN1A and CN1B connectors. When the connector is not capped, the 
light device may be damaged at the transit. In this case, replacing and repairing 
the light device are required.
