CAUTION
• Migrating plasticizer is used for vinyl tape. Keep the MR-J3BUS_M, and MR-J3BUS_M-A cables away from vinyl tape because the optical characteristic may
be affected. Generally, soft polyvinyl chloride (PVC), polyethylene resin (PE) and fluorine resin contain non-migrating plasticizer and they do not affect the
optical characteristic of SSCNET cable. However, some wire sheaths and cable ties, which contain migrating plasticizer (phthalate ester), may affect MR-
J3BUS_M and MR-J3BUS_M-A cables (made of plastic). In addition, MR-J3BUS_M-B cable (made of quartz glass) is not affected by plasticizer.
• If the adhesion of solvent and oil to the cord part of SSCNET cable may lower the optical characteristic and machine characteristic. To use the cable in that
environment, be sure to do the protection measures to the cord part.
• When keeping the Simple Motion module or servo amplifier, be sure to attach a cap to the connector part so that a dirt should not adhere to the end of
SSCNET connector.
• To protect a light device inside a connector from dust, a cap is attached to the SSCNET connector for the SSCNET cable. Therefore, do not remove a
cap until just before connecting the SSCNET cable. Also, when removing the SSCNET cable, make sure to attach a cap.
• Keep the cap and the tube for protecting light cord end of SSCNET cable in a plastic bag with a zipper included with the SSCNET cable to prevent them
from becoming dirty.
• When exchanging the Simple Motion module or servo amplifier, make sure to attach a cap to the SSCNET connector. When asking repair of Simple Motion
module or servo amplifier for some troubles, make also sure to attach a cap to the SSCNET connector. When a cap is not attached, the light device may be
damaged at the transit. In this case, exchange or repair of the light device is required.
Precautions for wiring
• Use separate cables for connecting to the Simple Motion module and for the power cable that creates surge and
inductance.
• The cable for connecting the Simple Motion module should be placed in the duct or secured in place by clamps. If the cable
is not placed in the duct or secured by clamps, unevenness or movement of the cable or careless pulling on it could result
in damage to the unit or cable or defective cable connections could cause mis-operation of the unit.
• If a duct is being used, separate the cables to connect the Simple Motion module from the power line duct, or use metal
piping. Ground the pipes securely after metal piping.
• Use the twisted pair shielded cable (wire size 0.3 mm
module side.
• Use separate shielded cables for the external input signal, forced stop input, and manual pulse generator/incremental
synchronous encoder input for connecting to the Simple Motion module. They can cause electrical interference, surges and
inductance that can lead to mis-operation.
• For wiring, refer to the following and each servo amplifier instruction manual.
