Quality Control

The quality of encoders is directly related to the stability and reliability of industrial automation systems. We have built a full-process quality control system, strictly screening suppliers from raw material procurement to ensure that the performance of core components meets standards; in the production process, we use high-precision equipment and standardized processes, and cooperate with online detection technology for real-time monitoring; in the finished product stage, we conduct rigorous tests such as high and low temperature, electromagnetic compatibility, and life aging to eliminate performance risks. Each encoder has passed multiple quality inspection levels, and its excellent quality has laid a solid foundation for intelligent manufacturing, providing customers with long-term and stable use guarantees.

Application Cases

This series of encoders is mainly used in servo drive control systems, providing accurate position and speed feedback for industrial automation equipment, precision machinery and robots, ensuring system positioning accuracy and operational stability.

2.Installation accessories



Phillips torque screwdriver

Metric 1.5mm across-flat hexagonal torque wrench

3-M2×5.5 Phillips pan head screw + flat washer combination

2-M3×3 hexagon socket set screw with socket point

4-M1.6×6 Phillips countersunk head screw

3.Installation sequence


Radial Rotor Installation:

① Slide the encoder rotor onto the motor shaft until it is 

properly positioned.

② Use a hexagonal torque wrench to sequentially tighten 

the two M3×3 hexagon socket-point set screws.


[Note]:

If the rotor height needs to be adjusted, tighten the screws 

after adjustment.


To prevent the screws from loosening, apply thread sealant to 

the threaded holes or use screws pre-applied with thread

 sealant.

 The recommended tightening torque is 7±0.2 kgf·cm.



Axial Rotor Installation:

① Slide the encoder rotor onto the motor shaft until the end

 faces are flush and align the four screw holes.

② Use a Phillips torque screwdriver to sequentially tighten 

the four screws (M1.6×6 Phillips countersunk screws).


[Note]:

After tightening the four countersunk screws, ensure that the

 screw head flatness is no higher than 0.3mm above

 the rotor surface; otherwise, it will interfere with the stator.


To prevent the screws from loosening, apply thread sealant to

 the threaded holes or use screws pre-applied with thread 

sealant. 

The recommended tightening torque is 1.2±0.2 kgf・cm.




Stator Installation:

① Place the encoder stator on the stator mounting surface 

and align the three screw holes.

② Use a Phillips torque screwdriver to sequentially tighten the 

three screws (M2×5.5 Phillips pan head screw + flat washer).


[Note]:

To prevent these screws from loosening, apply thread sealant

 to the threaded holes or use screws with pre-applied thread 

sealant. 

The recommended tightening torque is 2.8±0.2 kgf・cm.

To prevent the screws from loosening, apply threadlocker to the threaded holes or use screws pre-applied with threadlocker. 

The recommended tightening torque is 7±0.2 kgf·cm.



Axial Rotor Installation:

① Slide the encoder rotor onto the motor shaft until the end faces are flush and align the eight screw holes.

② Use a Phillips torque screwdriver to sequentially tighten the eight screws (M1.6×6 Phillips countersunk screws).


[Note]:

After the eight countersunk screws are installed, ensure that the screw head plane is no higher than 0.5mm above the rotor surface; otherwise, interference with the stator will occur.


To prevent the screws from loosening, apply threadlocker to the threaded holes or use screws pre-applied with threadlocker. 

The recommended tightening torque is 1.2±0.2 kgf·cm. kgf·cm.

Calibration Procedure

1.① Ensure the encoder is powered normally.

② Short-circuit TP1 and TP2. Hold for 1 second, then release. 

The green light will begin flashing at a rate of 8 times per second.

③ While the green light is flashing (within 1 minute), rotate the rotor in the same direction (at least 2.5 turns). 

If the indicator light remains on, calibration is successful.
