Appendix 2 Connection with servo amplifiers
Between the QD77MS and servo amplifiers or servo amplifier and servo amplifier
connected by SSCNET cable.
When absolute position detection control is executed, installed battery
(MR-J3BAT) to servo amplifier.

SSCNET connector
CAUTION
Be sure to connect SSCNET cable with the above connector. If the connection is mistaken, between
the QD77MS and servo amplifier cannot be communicated.
SSCNET connector to connect the SSCNET cable is put a cap to protect light device inside
connector from dust. For this reason, do not remove a cap until just before connecting SSCNET
cable. Then, when removing SSCNET cable, make sure to put a cap.
Keep the cap and the tube for protecting light cord end of SSCNET cable in a plastic bag with a
zipper of SSCNET cable to prevent them from becoming dirty.
Do not remove the SSCNET cable while turning on the power supply of QD77MS and servo
amplifier. Do not see directly the light generated from SSCNET connector of QD77MS or servo
amplifier and the end of SSCNET cable. When the light gets into eye, may feel something is wrong
for eye. (The light source of SSCNET cable complies with class1 defined in JISC6802 or
IEC60825-1.)
When exchanging the QD77MS or servo amplifier, make sure to put a cap on SSCNET connector.
When asking repair of QD77MS or servo amplifier for some troubles, make also sure to put a cap on
SSCNET 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.
