8.3.6. Method wiring
(1) Signal and communication cables is placing a high-voltage cable or power line over a
distance of 10cm, please not affected by the noise and magnetic field
(2) If possible use separate ducts for power cables and control lines.
(3) All cable should be the Shield cable.
✏
Note
According to the NFPA79 approved by the United States, when the shielded wire is not
used for wiring between a servo amplifier and a servo motor, the wiring must be
insulated from wiring of other control or signal circuits.
(Example: 100 mm or more for 20 A or less)
(4) Minimizing the loops
[Figure 8-13] Avoiding loops in wiring designs
✏
Note
:
Wires that form a loop make an efficient antenna. Run feed and return wires
together rather than allowing a loop to form. Twisting the pair further reduces the antennae effects
and can significantly reduce EMI.
(5) Excess cable

Cabling instructions
:
Do not coil excess cable of different types (for example, motor power and feedback) together. An efficient
transformer is formed at HF.
Cable lengths should ideally be trimmed to fit the application.
If excess cable cannot be trimmed, it should be laid in an 'S' or figure eight pattern (refer to the figure
below).
