Precautions for SSCNETIII cable wiring
SSCNET
cable is made from optical fiber. If optical fiber is added a power such as a major shock, lateral pressure, haul,
sudden bending or twist, its inside distorts or breaks, and optical transmission will not be available. Especially, as optical fiber
for MR-J3BUS_M, MR-J3BUS_M-A is 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 and servomotor. Be sure to use optical fiber within the range of operating temperature described in each servo
amplifier instruction manual. Read described item of this section carefully and handle it with caution.
■
Minimum bend radius
Make sure to lay the cable with greater radius than the minimum bend radius.
Do not press the cable to edges of equipment or others. For SSCNET
cable, the appropriate length should be selected with
due consideration for the dimensions and arrangement of Simple Motion module or servo amplifier. When closing the door of
control panel, pay careful attention for avoiding the case that SSCNET
cable is hold down by the door and the cable bend
becomes smaller than the minimum bend radius.
■
Tension
If tension is added on the SSCNET
cable, the increase of transmission loss occurs because of external force which
concentrates on the fixing part of SSCNET
cable or the connecting part of SSCNET
connector. At worst, the breakage of
SSCNET
cable or damage of SSCNET
connector may occur. For cable laying, handle without putting forced tension.
(Refer to each servo amplifier instruction manual for the tension strength of SSCNET
cable.)
■
Lateral pressure
If lateral pressure is added on the SSCNET
cable, the cable itself distorts, internal optical fiber gets stressed, and then
transmission loss will increase. At worst, the breakage of SSCNET
cable may occur. As the same condition also occurs at
cable laying, do not tighten up SSCNET
cable with a thing such as nylon band (TY-RAP).
Do not trample it down or tuck it down with the door of control box or others.
■
Twisting
If the SSCNET
cable is twisted, it will become the same stress added condition as when local lateral pressure or bend is
added. Consequently, transmission loss increases, and the breakage of SSCNET
cable may occur at worst.
■
Disposal
When incinerating optical cable (cord) used for SSCNET
cable, hydrogen fluoride gas or hydrogen chloride gas which is
corrosive and harmful may be generated. For disposal of SSCNET
cable, request for specialized industrial waste disposal
services that have incineration facility for disposing hydrogen fluoride gas or hydrogen chloride gas.
