What are the features and precautions of absolute encoders?

Absolute encoders are different from general encoders because their signal conversion functions are different, so the internal structure of the device is also significantly different from other types of encoders. Its internal structure mainly includes mechanical bits, optical code discs, and Rotate a single circle and gears, etc.

The definition of "absolute value" in the absolute encoder refers to all the position values inside the encoder. After the encoder is manufactured and shipped, all positions within its range have been determined "absolutely" in the encoder. After the origin is initialized, each position is independent and unique. Every time its internal and external data is refreshed and read, it does not depend on the previous data read. No matter it is inside the encoder or outside the encoder, it should not exist. The cumulative calculation of "count" and the previous reading, because such data is not "independent" or "unique" and "all positions in the range have been absolutely established in advance", so it does not conform to the meaning of the word "absolute".

What are the features and precautions of absolute encoders? Absolute encoder performance characteristics

The main function of the encoder is to be able to well connect the editing and processing of various data during the operation of the machine. Due to different purposes and machine performance, there are many types of encoders, among which absolute encoders are popular with users because of their unique performance characteristics.

Features of absolute encoder

1. No need to remember, no need to find reference point, with power-off memory function

2. Multiple communication protocols are available

3. Fast start speed, precise motion control of multiple axes

4. Anti-interference characteristics and corrosion resistance

5.High precision, high stability, high reliability

The biggest difference between the absolute value encoder and the general encoder equipment is the internal structure. The absolute value encoder uses a way similar to the rotating disk to work. When the encoder starts to run, the internal The rotating disc starts to work, and some special machines even have special scales. During the operation of the encoder, the vacancy left above can be used to directly hit the light source on the rotating disk of the encoder, so that there are scales and the assistance of the light source during operation, so we can easily adapt to our actual use Make reasonable positioning.

The functional performance of the absolute encoder is also reflected in the material of the equipment. We know that the environmental adaptability of the absolute encoder needs to be guaranteed by the material. So what are the main aspects of the material performance of the absolute encoder? First of all, on the housing, the absolute value encoder uses a suitable alloy material as the basis for environmental adaptability, and at the same time, it is easy to form in process.

Not only that, the shell material of the absolute encoder has many advantages, such as strength control and corrosion resistance. Excellent material performance is the foundation of the equipment environment adaptability. For users In other words, when purchasing the corresponding absolute encoder, you can first select the appropriate machinery and equipment from the material of the equipment. Of course, there will be more outstanding performance in many performance indicators such as data processing speed. Excellent workmanship and good performance guarantee the performance of the absolute encoder.

What are the features and precautions of absolute encoders? Precautions

The absolute value encoder is a precision instrument. Do not knock or impact, handle it gently, and use it carefully. Ensure that the power supply of the absolute value encoder is within the rated range, and isolate it to prevent the large-scale starting electrical in the power grid from impacting the absolute value encoder. In a strong electromagnetic interference environment, it is best to use a dedicated line for the signal line, such as a pair of pairs Shielded cable. The signal wire of the absolute encoder should be well grounded: within 2 meters, both ends of the shielding net in the cable should be grounded. For a longer distance, the metal shell of the absolute encoder should be grounded, and the shielding net of the built-in cable should be suspended. The signal extension cable shielding net is grounded at the signal receiving end at a single end; if the signal cable is long or used outdoors, the signal cable should be covered with a metal sleeve, and both ends of the metal pipe should be grounded.
