2.3 Servo cable installation
DS5 series servo motor adopts communication encoder, which may cause uncertain influence due to
improper use and environmental factors. When installing power cable and encoder cable, please pay
attention to the following instructions.
2.3.1 Cable selection
Our regular cable materials include ordinary cable and high flexible cable. The adapter cable connector
for motors with 80 flange or less is divided into aviation plug and amp plug; the adapter cable
connector for motors with 80 flange or more is aviation plug.
The cable selected by the customer needs to define the operating conditions on site.
If the cable is used in general occasions, please select the cable from other manufacturers (2.3.2
specifications of Xinje cable) in strict accordance with the specifications given by Xinje. If the cable is
used in unconventional occasions, please select the cable according to the actual working conditions to
be superior to the existing specifications of Xinje.
1. In normal situations, the following points should be noted:

For pulse command signal cable, please ensure wiring less than 3m.

The encoder cable shall be within 20 meters. It is recommended to select special cable if it is
more than 20 meters. The wire diameter of encoder cable depends on the length of encoder
cable used on site. The longer the cable is, the greater the wire resistance is, and the more
severe the voltage attenuation or signal distortion is, which is likely to cause pulse loss or no
signal can be detected. Therefore, in general, the customized special cable should be selected
if it is more than 20 meters.

The power cable diameter depends on the current condition of the motor. Generally, the wire
diameter is 1/10 of the maximum current of the motor. For example, the maximum current of
the motor is 60A, and the wire diameter of 6mm²
is selected.

In case of interference, it is necessary to separate strong and weak current. It is recommended
to separate power cable from encoder cable and signal cable.

Ensure the correct grounding of servo driver and servo motor. The grounding resistance is not
more than 4Ω, and the grounding depth is more than 2m. It is recommended to use 4*40
angle galvanized steel or 40mm diameter galvanized steel pipe;

If the customer makes the wire by himself, the cable specification please refer to chapter
2.3.2 Xinje cable specification, the welding reliability shall be ensured when making the wire
to avoid false welding, bridge connection, wrong welding, missing welding, etc., and the
continuity of both ends of the cable can be tested after the welding is completed.
2. In unconventional occasions, the following items shall be noted:
(1) Occasions of dragging and bending cables

Do not bend the cable or bear the tension. As the core diameter of signal cable is only 0.2mm
or 0.3mm, it is easy to break, please pay attention to it when using.

When the cable needs to be moved, please use flexible cable. Ordinary cable is easy to be
damaged after long-term bending. Small power motor (motor below 80 flange) with its own
cable can not be used for cable movement.

When using cable protection chain, please ensure that:
①
The bending radius of the cable is more than 10 times of the outer diameter of the cable;
②
The wiring in the cable protection chain shall not be fixed or bundled, only the two
immovable wires end in the cable protection chain shall be bound and fixed;
③
Do not twist the cable;
④
The duty cycle in the cable protection chain shall be less than 60%;
⑤
Do not mix the cables with too big difference in appearance. The thin wire will be broken
by the thick wire. If it is necessary to mix the wiring, partition device is arranged in the
middle of the cable.
