3.9 SSCNET
cable connection
POINT
Do not see directly the light generated from CN1A CN1B connector of servo
amplifier or the end of SSCNET
cable.
When the light gets into eye, may feel something is wrong for eye.
(The light source of SSCNET
complies with class1 defined in JIS C6802 or
IEC60825-1.)
(1) SSCNET
cable connection
For CN1A connector, connect SSCNET
cable connected to controller in host side or servo amplifier.
For CN1B connector, connect SSCNET
cable connected to servo amplifier in lower side.
For CN1B connector of the final axis, put a cap came with servo amplifier.

(2) How to connect/disconnect cable.
POINT
CN1A CN1B connector is put a cap to protect light device inside connector
from dust.
For this reason, do not remove a cap until just before mounting SSCNET
cable.
Then, when removing SSCNET
cable, make sure to put a cap.
Keep the cap for CN1A CN1B connector and the tube for protecting light
code end of SSCNET
cable in a plastic bag with a zipper of SSCNET
cable to prevent them from becoming dirty.
When asking repair of servo amplifier for some troubles, make sure to put a
cap on CN1A
CN1B connector.
When the connector is not put a cap, the light device may be damaged at the
transit.
In this case, exchange and repair of light device is required.
(a) Mounting
1) For SSCNET
cable in the shipping status, the tube for protect light code end is put on the end of
connector. Remove this tube.
2) Remove the CN1A
CN1B connector cap of servo amplifier.
