4.3.2 Control cable

All analog signal cables, communication cables, and encoder cables must be shielded cables.
Analog signal cables need to be double-shielded twisted-pair cables (as shown in figure a). Use one separate
shielded twisted pair for each signal. Do not use the same ground wire for different analog signals.
Communication cables and encoder cables need to be single-shielded twisted-pair cables (as shown in
figure b). The shield layer of cable is connected to the system PE by means of a 360-degree connection or
twisting into a single bundle, and the exposed shield layer is wrapped with insulating tape to prevent
interference introduced by the shield layer in contact with other equipment and structural components.
The keypad needs to be connected by using a network cable. In complicated electromagnetic environments,
a shielded network cable is recommended.
Note: Analog signals and digital signals cannot share a same cable, and their cables must be routed
separately.

4.3.3 Wiring suggestions

Motor cables and input cables in a drive system are interference cables, while communication cables,
encoder cables, analog signals, and high-speed signal cables are sensitive cables. It is recommended that
you arrange the motor cables, input power cables, and control cables separately in different trays, reducing
electromagnetic interference caused by the du/dt of the inverter output to other cables. The general cable
arrangement rules are shown in Figure 4-3. The recommended values for the spacing between sensitive and
interference cables are shown in the following table.
