1. Eltra Encoder Malfunction: This refers to a fault in the encoder's components, preventing it from generating and outputting the correct waveform. In this case, the encoder needs to be replaced or its internal components repaired.

2. Encoder Connection Cable Malfunction: This is a common and frequently encountered fault during maintenance, and should be the primary consideration. It is usually caused by an open circuit, short circuit, or poor contact in the encoder cable. The cable or connector needs to be replaced. Special attention should be paid to whether the cable is loosely secured, causing a break in the solder joint or an open circuit; in this case, the cable needs to be tightened.

3. Encoder +5V Power Drop: This refers to a +5V power supply that is too low. It should generally not be lower than 4.75V. The cause of a low voltage is a power supply malfunction or excessive resistance in the power transmission cable, leading to power loss. In this case, the power supply needs to be repaired or the cable replaced. 4. Absolute encoder battery voltage drop: This fault usually has a clear alarm meaning.

High-speed mounting: Installed on the motor shaft (or gear connection). The advantage of this method is high resolution. Since multi-turn encoders have 4096 turns, the motor rotation count is within this range, fully utilizing the range to improve resolution. The disadvantage is that there is gear backlash error after the moving object passes through the reduction gear. It is generally used for unidirectional high-precision control and positioning, such as roll gap control in steel rolling. Additionally, when the encoder is directly installed at the high-speed end, motor vibration must be minimal, otherwise the encoder may be damaged.

Low-speed mounting: Installed after the reduction gear, such as on the shaft end of a hoisting wire rope drum or the shaft end of the next reduction gear. This method eliminates gear backlash, making measurement more direct and accurate. This method is generally used for long-distance positioning, such as various lifting equipment and feeding trolley positioning.

Eltra encoders are devices that encode signals (such as bit streams) or data and convert them into a signal form that can be used for communication, transmission, and storage. An encoder converts angular or linear displacement into electrical signals; the former is called a code disk, and the latter a code scale. Encoders can be classified into contact and non-contact types according to their readout method; and into incremental and absolute types according to their working principle. Incremental encoders convert displacement into periodic electrical signals, then convert these signals into counting pulses, using the number of pulses to represent the magnitude of the displacement. Absolute encoders assign a unique digital code to each position; therefore, their reading depends only on the starting and ending positions of the measurement, and is independent of the intermediate steps.

Eltra has over 20 years of experience in the production and sales of sensor technologies, particularly in the encoder industry. Currently, it produces up to 15,000 different sensor models and serves 3,000 customers worldwide. Eltra's comprehensive product range is a major feature, including standard products such as linear encoders and absolute encoders; specialized products such as draw-wire and magnetic encoders, absolute bus systems, metric encoders, electronic handwheels, and intrinsically safe explosion-proof encoders; as well as photoelectric and inductive proximity switches, oscillating sensors, linear potentiometers, and related accessories. All Eltra products undergo rigorous testing under strict conditions for extended periods, ensuring stringent quality. They are also certified by CE, ISO9001:2000, UL/CSA40, and ATEX. Eltra's sales network spans the globe, providing customers with fast, reliable, and high-quality pre-sales and after-sales service. Eltra encoders generate electrical signals that are processed by CNC (Computer Numerical Control) systems, PLCs, and control systems. These sensors are primarily used in machine tools, material processing, motor feedback systems, and measurement and control equipment. In Eltra encoders, angular displacement conversion utilizes the photoelectric scanning principle. The reading system is based on the rotation of a radially graduated disc, which consists of alternating transparent and opaque windows. The entire system is illuminated vertically by a single infrared light source, projecting the image on the disc onto the surface of a receiver covered by a grating called a collimator, which has the same windows as the optical disc. The receiver's function is to sense the light changes caused by the disc's rotation and convert these changes into corresponding electrical changes. Generally, the rotary encoder also provides a speed signal, which is fed back to the frequency converter to adjust its output data. Fault symptoms: 1. When the rotary encoder is faulty (no output), the frequency converter cannot function properly, running very slowly, and after a while, the frequency converter will activate its protection mode, displaying "PG disconnected"... Only a combined action will work. To raise the electrical signal to a higher level and generate a square wave pulse without any interference, electronic circuitry is required. The connection method between the encoder PG and the vector frequency converter must correspond to the encoder PG model. Generally, encoder PG models are divided into three types: differential output, open collector output, and push-pull output. The signal transmission method must take into account the inverter PG card interface; therefore, selecting the appropriate PG card model or configuring it correctly is crucial.
