● Motor cable
Use shielded cables for motor cables. Minimize the distance between the cabinet
module and the motor, and route the motor cables separately from other cables.
Also, avoid long‑distance parallel routing of the motor cables and other cables to
reduce electromagnetic interference caused by rapid changes in the output
voltage of the AC drive.
● Power cable
Use shielded cables, or shield all the cables from the cabinet module to the motor
by using conduits.
● Control cables and power supply cables
If the power supply cables and control cables must be intersected, make the
intersection angle 90 degrees.
8.4.5 Routing Recommendations
Routing disturbing cables and sensitive cables
Route cables that transmit different types of signals through different routes.
Separate the disturbing cables from sensitive cables by a distance of at least 30 cm.
When two types of cables must be intersected, the intersection angle must be 90
degrees to avoid interference, as shown in the following figure.
Figure 8‑54 Routing disturbing cables and sensitive cables
Routing cables that transmit different types of signals
Route cables that transmit different types of signals through different routes and
separate different types of signals with equipotential signals. When routing cables
that transmit the same type of signals, lay equipotential signal cables at the outer
layers and lay equipotential bondings as many as possible in the middle if possible, as
shown in the following figure.
