4 INSTALLATION AND WIRING
POINTS
(1) Be sure to connect SSCNET cable with the above connector. If the
connection is mistaken, between the Motion controller and servo amplifier
cannot be communicated.
(2) Forced removal of the SSCNET cable from the Motion controller will damage
the Motion controller and SSCNET cables.
(3) After removal of the SSCNET cable, be sure to put a cap on the SSCNET
connector. Otherwise, adhesion of dirt deteriorates in characteristic and it may
cause malfunctions.
(4) Do not remove the SSCNET cable while turning on the power supply of
Motion controller and servo amplifier.
Do not see directly the light generated from SSCNET connector of Motion
controller 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.)
(5) If the SSCNET cable is added a power such as a major shock, lateral
pressure, haul, sudden bending or twist, its inside distorts or brakes, and
optical transmission will not be available.
Be sure to take care enough so that the short SSCNET cable is added a
twist easily.
(6) Be sure to use the SSCNET cable within the range of operating temperature
described in this manual. Especially, as optical fiber for MR-J3BUS M and
MR-J3BUS M-A are made of synthetic resin, it melts down if being left near
the fire or high temperature. Therefore, do not make it touched the part which
becomes high temperature, such as radiator or regenerative option of servo
amplifier, or servomotor.
(7) When laying the SSCNET cable, be sure to secure the minimum cable bend
radius or more.
(8) Put the SSCNET cable in the duct or fix the cable at the closest part to the
Motion controller with bundle material in order to prevent SSCNET cable
from putting its own weight on SSCNET connector.
When laying cable, the optical cord should be given loose slack to avoid from
becoming smaller than the minimum bend radius, and it should not be twisted.
When bundling the cable, fix and hold it in position by using cushioning such
as sponge or rubber which does not contain migratable plasticizing.
If using adhesive tape for bundling the cable, fire resistant acetate cloth
adhesive tape 570F (Teraoka Seisakusho Co., Ltd) is recommended.
