the encoder cable is connected first, the encoder may fail due to the potential
difference between PE.
◆When wiring, please make sure that the pins are arranged correctly.
◆Connectors are made of resin. Do not apply shock to avoid damaging the
connector.
◆When carrying out the operation under the condition that the cable remains
connected, it is necessary to grasp the main body of the servo motor. If only the
cable is seized for handling, it may damage the connector or pull the cable off.
◆If bending cable is used, full attention should be paid to the wiring operation
and stress should not be applied to the connector part. If the stress is applied to
the connector part, the connector may be damaged.
2.2.3 Installation environment
➢ Do not use this product near corrosive and flammable gas environments such as hydrogen sulfide, chlorine,
ammonia, sulfur, chlorinated gas, acid, alkali, salt, etc.
➢ In places with grinding fluid, oil mist, iron powder, cutting, etc., please choose motor with oil seal.
➢ A place away from heat sources such as stoves;
➢ Do not use motor in enclosed environment. Closed environment will lead to high temperature and shorten
service life of motor.
2.3 Servo cable installation
DF3E 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 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
