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.

3) With holding a tab of SSCNET
cable connector, make sure to insert it into CN1A CN1B connector
of servo amplifier until you hear the click.
If the end face of optical code tip is dirty, optical transmission is interrupted and it may cause
malfunctions.
If it becomes dirty, wipe with a bonded textile, etc.
Do not use solvent such as alcohol.

(b) Removal
With holding a tab of SSCNET
cable connector, pull out the connector.
When pulling out the SSCNET
cable from servo amplifier, be sure to put the cap on the connector
parts of servo amplifier to prevent it from becoming dirty.
For SSCNET
cable, attach the tube for protection optical code's end face on the end of connector.

3.10 Connection of servo amplifier and servo motor
CAUTION
During power-on, do not open or close the motor power line. Otherwise, a
malfunction or faulty may occur.
3.10.1 Connection instructions
WARNING
Insulate the connections of the power supply terminals to prevent an electric
shock.
CAUTION
Connect the wires to the correct phase terminals (U, V, W) of the servo amplifier
and servo motor. Not doing so may cause unexpected operation.
Do not connect AC power supply directly to the servo motor. Otherwise, a fault
may occur.
POINT
Refer to section 11.1 for the selection of the encoder cable.
This section indicates the connection of the servo motor power (U, V, W). Use of the optional cable and
connector set is recommended for connection between the servo amplifier and servo motor. When the
options are not available, use the recommended products. Refer to section 11.1 for details of the options.
(1) For grounding, connect the earth cable of the servo motor to the protective earth (PE) terminal (
) of the
servo amplifier and connect the ground cable of the servo amplifier to the earth via the protective earth of
the control box. Do not connect them directly to the protective earth of the control panel.

(2) Do not share the 24VDC interface power supply between the interface and electromagnetic brake. Always
use the power supply designed exclusively for the electromagnetic brake.
