1.4 Selection of other accessories
1.4.1 Selection of regenerative resistance
When the servo motor is driven by the generator mode, the power returns to the servo amplifier side, which is
called regenerative power. The regenerated power is absorbed by charging the smooth capacitor of the servo
amplifier. After exceeding the rechargeable energy, the regenerative resistance is used to consume the
regenerative power.
The servo motor driven by regenerative (generator) mode is as follows:
➢The deceleration stop period during acceleration and deceleration operation;
➢Running vertically and axially;
➢When the external load drives the motor to rotate.
Servo driver model
Regenerative resistance connection terminals
DF3E-□□□□
Use external regenerative resistance, connect regenerative resistance to RB+
and RB- terminals, P0-25 = power value, P0-26 = resistance value.
The following table is the recommended specifications of external regenerative resistance for each type of motor.

Note:
(1) The smaller the resistance is, the faster the discharge will be, but the smaller the resistance is, the easier the
breakdown resistance will be. Therefore, please close to the the lower limit but not be less than the lower limit
when choosing the type.
(2) When wiring, please use high-temperature flame-retardant wire, and the regenerative resistance surface can
not contact with the wire.
1.4.2 Fuse selection
The role of fuse in the circuit is over-current protection, also known as short-circuit protection.
When there is a short circuit, the current in the circuit is the largest, which undoubtedly far exceeds the rated
current of the equipment. If the circuit breaker is not cut off in time, the electrical equipment will soon be burned
due to the high current. Therefore, in order to cut off the circuit in time and protect the equipment from damage,
the fuse is used, the principle is that the fuse can be fused quickly before the equipment is damaged at the moment
when a large current is generated in the circuit, so as to cut off the circuit.

Description
◆When the pulley is installed on the servo motor shaft with keyway, the
screw hole is used at the end of the shaft. In order to install the pulley, the
double-headed nails are inserted into the screw holes of the shaft, the washer is
used on the surface of the coupling end, and the pulley is gradually locked with
the nut.
◆For the servo motor shaft with keyway, use the screw hole at the end of the
shaft to install. For shaft without keyway, friction coupling or similar methods
are used.
◆When the pulley is dismantled, the pulley mover is used to prevent the
bearing from being strongly impacted by the load.
◆To ensure safety, protective covers or similar devices, such as pulleys
installed on shaft, are installed in the rotating area.
Centering
◆When installing the servo motor, make it conform to the centering accuracy
requirement shown in the picture below. If the centering is inadequate, vibration

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 6mm²is 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
