Eltra encoders generate electrical signals that are processed by CNC (Computer Numerical Control) systems, PLCs (Programmable Logic Controllers), and control systems. These sensors are mainly 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 radial indexing disk, which consists of alternating transparent and opaque windows. The entire system is illuminated vertically by an infrared light source, projecting the image on the disk onto the surface of a receiver covered with a grating called a collimator, which has the same window as the optical disc. The receiver's function is to sense the light changes caused by the disk's rotation and convert these changes into corresponding electrical changes. Generally, rotary encoders also provide a speed signal, which is fed back to the frequency converter to adjust its output data. Fault Phenomenon: 1. When the rotary encoder is faulty (no output), the frequency converter cannot work normally, its operating speed becomes very slow, and after a while, the frequency converter will activate protection, displaying "PG disconnected"... Only a combined action can function. 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 interface of the frequency converter PG card; therefore, selecting the appropriate PG card model or setting it correctly is crucial.

Eltra Encoder: An encoder is a device that encodes and converts signals (such as bit streams) or data into a signal form that can be used for communication, transmission, and storage. An encoder converts angular displacement or linear displacement into electrical signals; the former is called a code disk, and the latter a code scale. According to the readout method, encoders can be divided into contact and non-contact types; according to the working principle, encoders can be divided into incremental and absolute types. 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 specific digital code to each position; therefore, their reading depends only on the start and end positions of the measurement, and not on the intermediate steps.

Main Classifications

Encoders can be classified as follows:

1. Classification by the method of engraving the code disk:

(1) Incremental type: This type emits a pulse signal for each unit angle rotated (some emit sine and cosine signals, which are then subdivided and chopped to produce higher frequency pulses). Typically, it outputs A, B, and Z phases. Phases A and B are pulses delayed by 1/4 cycle, allowing for differentiation between forward and reverse rotation. Furthermore, the rising and falling edges of phases A and B can be used for 2- or 4-fold frequency multiplication. Phase Z is a single-turn pulse, emitting one pulse per revolution. (2) Absolute value type: For each revolution, a binary value corresponding to each reference angle is emitted. Multiple positions can be recorded and measured using an external revolution-counting device.

2. According to the signal output type, it is divided into: voltage output, open collector output, push-pull complementary output, and long-line drive output. EL90A1000Z8/24P-Z8/24P10X3PR
