1. Servo motor encoder is a product installed on the servo motor, which is equivalent to a sensor.
2. Do speed closed-loop and azimuth closed-loop to complete accurate speed regulation and accurate azimuth control.
3. The servo motor itself comes with an encoder, which can be used to pulse with PLC by converting the servo electronic gear ratio to control the distance of servo operation
4. The servo system has three closed-loop control, from the outside to the inside, the azimuth ring, the speed ring, the current ring, and the three rings are used in the azimuth control. Only the speed loop and the current loop are used for speed control.
5. The speed reaction of the motor and the practical orientation reaction of the rotor can allow the driver to identify the specific model of the motor.
6. It can remember the magnetic pole orientation of the motor, and the servo driver can best control the servo motor according to the magnetic pole orientation.
7. Servo motor encoder is a sensor installed on the servo motor to measure the magnetic pole orientation and servo motor angle and speed, from the different physical media, the servo motor encoder can be divided into photoelectric encoder and magnetoelectric encoder, in addition to the resolver is also a special servo encoder, the market is basically used photoelectric encoder, but the magnetoelectric encoder as a rising star, has the characteristics of reliability, cheap price, anti-pollution and so on.
8. The function of the servo motor encoder is to react the angle (direction) of the servo motor rotation to the servo driver, and the servo driver will control the servo motor rotation after receiving the reaction signal to form a closed-loop control to accurately control the direction and speed of the servo motor rotation.
9. In addition to being able to react to the stroke of the servo motor and compare it with the pulse announced by the PLC, the servo motor encoder can reach a closed-loop system; It also reflects the speed of the servo motor, the orientation of the rotor practice, and allows the drive to identify the specific model of the motor. To do closed-loop accurate control of the CPU, the CPU needs to know the current position of the rotor when it is started, which is also given by the servo motor encoder.
10. Do not apply direct impact to the shaft when installing the servo motor.
(1) The connection between the servo motor encoder shaft and the machine should use a flexible adapter. When attaching the adapter to the shaft, do not press it in. Even if an adapter is used, it is necessary to be careful that a load greater than the allowable load may be applied to the shaft due to a defective device, or a core dial phenomenon may occur.
(2) The life of the bearing is related to the application conditions. It is particularly affected by the bearing load. If the bearing load is smaller than the specified load, the life of the bearing can be greatly extended. Do not disassemble the encoder, as this will compromise oil and drip resistance. Anti-drip products should not be immersed in water for a long time, and should be scrubbed clean when there is water or oil on the surface.

Buke human-machine interface - anti-interference countermeasures of PLC controller and human-machine interface
1. Adopt a power supply with excellent performance to suppress the interference introduced by the power grid.
For the power supply supplied by the PLC controller, the non-power line power supply should be adopted, and the special line power supply should be used directly from the main bus of the low-voltage distribution room. Isolation transformers are selected, and the transformer capacity should be larger than the actual needs.

Buke servo motor - AC servo motor vibration fault analysis
Mechanical
1. Bearing
The bearing clearance on the lead screw housing is too large after wear, or the bearing roller elements and cages are severely worn due to the lack of grease in the bearing, resulting in excessive loads. After bearing wear, the clearance is too large, which will cause the coaxiality error between the center of the motor rotor and the center of the lead screw.
