Traditional detector coding requires manual mechanical dialing to complete, which has low coding efficiency, high technical requirements, and is prone to coding errors. In addition, for the convenience of coding, a coding port needs to be left at the bottom of the detector, which can easily cause poor sealing of the detector against dust and moisture, resulting in a deterioration of the overall performance of the detector.
The electronic encoder uses keyboard operation to input decimal numbers, which is simple and easy to learn. Electronic encoders can be used to read and write the address and sensitivity of detectors, as well as the address and working mode of read-write module products; And electronic encoders can be used to browse equipment batch numbers. The electronic encoder can also be used to set the address of the ZF-GST8903 fire display panel, the total number of lights, and the corresponding user code for each light. On site debugging and maintenance are very convenient.

1. Encoder malfunction: refers to the failure of the encoder's own components,
Resulting in its inability to generate and output correct waveforms. In this case, it is necessary to replace the encoder or repair its internal components.
2. Encoder connection cable fault: This type of fault has the highest probability of occurrence and is often encountered during maintenance, and should be a priority factor to consider. Usually, it is due to open circuit, short circuit or poor contact of the encoder cable, in which case the cable or connector needs to be replaced. Special attention should also be paid to whether the loosening caused by loose cable fixation leads to welding or circuit breaking. In this case, the cable should be clamped tightly.
3. Encoder+5V power supply drop: refers to the situation where the+5V power supply is too low, usually not lower than 4.75V. The reason for the low voltage is due to power supply failure or high resistance of the power transmission cable, which causes losses. In this case, the power supply needs to be repaired or the cable needs to be replaced.
4. The voltage drop of the encoder battery: This fault usually has a clear alarm meaning, and the battery needs to be replaced. If the reference point position memory is lost, the operation of returning to the reference point must also be performed.
5. The shielded wire of the encoder cable is not connected or detached: this will introduce interference signals, make the waveform unstable, and affect the accuracy of communication. It is necessary to ensure reliable welding and grounding of the shielded wire.
6. Loose installation of encoder: This fault can affect the accuracy of position control, causing excessive positional deviation during stopping and movement, and even generating servo system overload alarm as soon as the machine is turned on. Please pay special attention.
7. Grating contamination can cause a decrease in signal output amplitude, and it is necessary to gently wipe off the oil stains with degreasing cotton.
A encoder is a photoelectric rotary measuring device that directly converts the measured angular displacement into a digital signal (high-speed pulse signal).
If encoders are classified based on signal principles, there are incremental encoders and type encoders.
We usually use incremental encoders, which can directly input the output pulse signal of the rotary encoder to the PLC, and use the PLC's high-speed counter to count its pulse signal to obtain measurement results. Different models of rotary encoders have different numbers of output pulses. Some rotary encoders output three-phase pulses of A, B, and Z, some only have two phases of A and B, and the simplest one only has phase A.
The encoder has 5 leads, including 3 pulse output lines, 1 COM terminal line, and 1 power line (OC gate output type). The power supply of the encoder can be an external power supply or directly use the DC24V power supply of the PLC. The "-" end of the power supply should be connected to the COM end of the encoder, and the "+" end should be connected to the power supply end of the encoder. The COM end of the encoder is connected to the input COM end of the PLC, and the A, B, and Z phase pulse output lines are directly connected to the input end of the PLC. A and B are pulses that are 90 degrees apart, and the Z phase signal has only one pulse when the encoder rotates once, usually used as a basis for zero point. When connecting, attention should be paid to the response time of the PLC input. The rotary encoder also has a shielded wire, which should be grounded during use to improve anti-interference performance.

working principle
A photoelectric encoder with a central axis, which has circular markings for light and dark, is read by photoelectric emitting and receiving devices to obtain four sets of sine wave signals combined into A, B, C, and D. Each sine wave has a phase difference of 90 degrees (360 degrees relative to one cycle), and the C and D signals are reversed and superimposed on the A and B phases to enhance stable signals; Additionally, output a Z-phase pulse for each revolution to represent the zero reference position.
Due to the 90 degree difference between phase A and phase B, the forward and reverse rotation of the encoder can be determined by comparing whether phase A is ahead or phase B. By using the zero position pulse, the zero position reference position of the encoder can be obtained. The materials of encoder encoders include glass, metal, and plastic. Glass encoders deposit very thin engraved lines on glass, which has good thermal stability and high accuracy. Metal encoders directly engrave lines with or without lines, which are not fragile. However, due to the thickness of metal, the accuracy is limited, and its thermal stability is one order of magnitude worse than that of glass. Plastic encoders are economical and have low cost, but their accuracy, thermal stability, and lifespan are all inferior.
Resolution - The number of lines provided by an encoder for each 360 degree rotation is called resolution, also known as resolution division or directly referred to as number of lines. Generally, it ranges from 5 to 10000 lines per rotation.

After the encoder generates an electrical signal, it is processed by CNC, programmable logic controller (PLC), control system, etc. These sensors are mainly used in the following areas: machine tools, material processing, motor feedback systems, and measurement and control equipment. The conversion of angular displacement in ELTRA encoder adopts the principle of photoelectric scanning. The reading system is based on the rotation of a radial indexing disk, which is composed of alternating transparent and opaque windows. This system is entirely illuminated vertically by an infrared light source, which projects the image on the plate onto the surface of the receiver. The receiver is covered with a layer of grating called a collimator, which has the same window as the optical disc. The job of the receiver is to sense the light changes generated by the rotation of the optical disc, and then convert the light changes into corresponding electrical changes. Generally, a rotary encoder can also obtain a speed signal, which needs to be fed back to the frequency converter to adjust the output data of the frequency converter. Fault phenomenon: 1. When the rotary encoder is broken (no output), the frequency converter cannot work normally and runs slowly. In addition, after a while, the frequency converter protection will display "PG disconnected" Joint actions are necessary to be effective. To raise the electrical signal to a higher level and generate square wave pulses without any interference, electronic circuits must be used for processing. The wiring of the encoder PG and the connection method between the parameter vector frequency converter and the encoder PG must correspond to the model of the encoder PG. Generally speaking, there are three types of encoder PG models: differential output, open collector output, and push-pull output. The signal transmission method must consider the interface of the frequency converter PG card, so choose the appropriate PG card model or set it reasonably
