Rotary encoder, absolute
An encoder is an electronic measuring device used to determine the position and/or speed of a rotating shaft. There are two types of encoder: absolute and incremental.
An absolute encoder outputs a unique signal for each position of the shaft. In other words, an absolute encoder provides the absolute position of the shaft. An absolute encoder consists of a rotating part that is mounted on the shaft and a fixed part that evaluates the signals from the rotating part. The rotating part usually has a pattern of slots or marks arranged in a certain code.
As the shaft rotates, the fixed part of the encoder detects the pattern and decodes the absolute position of the shaft. This position information is typically output in binary form, with each position producing a unique binary signal. The resolution of an absolute encoder is specified in bits and determines the number of possible positions. A typical absolute encoder can have a resolution of 12 or 16 bits, which means it can generate 4096 or 65536 possible positions.
Absolute encoders are used in many applications such as CNC machines, robots, packaging machines, printing machines and many other applications where accurate positioning is required. Unlike incremental encoders, which measure the movement of a shaft relative to a specific reference position, absolute encoders provide direct and independent position measurement without the need for a reference position.

If the encoder is moved when it is de-energized, the position value will determine the then current value immediately after the encoder power supply is switched on. Absolute encoders output position information in the form of codes, such as Gray code.
For absolute encoders, a distinction is made between the optical (internal code disk) and magnetic scanning principle.
Optical scanning principle
The optical encoder operates with an integrated code disk that is permanently connected to the encoder shaft. These code discs are made of plastic, glass or metal. Plastic pulleys have a relatively low mass and are relatively resistant to shock and vibration thanks to the low moment of inertia. For higher operating temperatures, slotted code discs made of metal are used. These metal code discs have dash-shaped openings.
A light source such as LED or infrared light generates a light/dark signal on the receiver located behind the code disk. One revolution of the shaft and thus of the code disc produces a quasi-sinusoidal signal. A higher resolution of the output signal is accompanied by a larger diameter of the code disk and thus an increase in the size of the design.
Magnetic scanning principle
With magnetic incremental encoders, a permanent magnet is mounted on the encoder shaft. The magnetic field is detected by Hall sensors and converted into a corresponding output signal. Magnetic encoders are insensitive to external influences such as vibration, shock, humidity and dust.
The rotary encoders with magnetic scanning are usually more robustly designed and can be built more compactly. Absolute encoders with optical scanning stand for higher accuracy and dynamics. Furthermore, a distinction is made between single-turn encoders and multi-turn encoders .
Singleturn encoders
resolve one revolution (360°) into n-steps. After one revolution, the measured values repeat. The number of encoder revolutions cannot be detected by the electronics.
Multiturn encoders
record the angular position and the number of revolutions. A reduction gear is integrated next to the coding disk, via which the number of revolutions is recorded. This means that the absolute values can also be recorded over several revolutions.

What is a rotary encoder, absolutely?
An absolute rotary encoder is an electronic device that is used to measure the absolute position of a shaft or object. It consists of a rotating part and a fixed part. The rotating part contains a coded disk or ring with specific patterns that can be read by a sensor in the fixed part of the encoder.
The coded pattern on the disk or ring enables the encoder to determine the exact position of the rotating part in a specific area. This means that the encoder is able to determine the absolute position independently of previous positions or movements.
An absolute rotary encoder is often used in industrial applications such as machine control, robotics, automation and positioning technology. It can be used to monitor and control the exact position of an axis or a motor.

How does a rotary encoder work, absolutely?
An absolute rotary encoder is an electronic device that is used to measure the absolute position of a shaft or object. It consists of a rotating element that is connected to the shaft or object and a sensor that detects the rotation of the element and determines the absolute position.
The encoder can use various technologies to measure the position. A common method is to use optical sensors that scan on a disk pattern. The disk has a series of patterns or codes that represent the position. When the rotating element turns, the pattern moves in front of the sensors and the system can recognize the position based on the detected patterns.
Another approach is to use magnetic sensors. The rotating element contains magnets or magnetic patterns that can be detected by the sensors. The sensors can then analyze the magnetic fields and calculate the position.
As soon as the encoder has determined the position, it normally sends this as a digital signal to a control system or a computer. The output can be in various formats, including binary codes or analog signals.
The advantage of an absolute rotary encoder is that it can determine the exact position of the rotating element independently of previous positions or rotations. This is particularly useful in applications where precise positioning is required, such as robotics, CNC machine control or industrial automation.

What are the advantages of an absolute rotary encoder compared to an incremental rotary encoder?
An absolute rotary encoder has several advantages over an incremental rotary encoder:
1. Positioning: An absolute encoder can display the exact position of the encoder in a specific range without the need for referencing. With an incremental encoder, on the other hand, a reference position must always be known in order to determine the exact position.
2. Simple commissioning: An absolute rotary encoder does not require initialization or referencing at start-up, as it automatically detects and displays the position. An incremental encoder, on the other hand, must first be referenced in order to determine the position.
3. Robustness: As an absolute rotary encoder indicates the exact position, it is less susceptible to errors or inaccuracies when determining the position. An incremental encoder, on the other hand, can be inaccurate due to loss of pulses or other errors in position determination.
4. Reliability: As an absolute encoder indicates the exact position, it is generally more reliable and less susceptible to faults or failures. An incremental encoder can be affected by faults or failures in the pulse generation.
5. Multiple positioning: An absolute rotary encoder can display several positions simultaneously as it recognizes the absolute position. An incremental encoder, on the other hand, can only display the relative position and requires continuous monitoring to determine the exact position.
Overall, an absolute rotary encoder offers more precise and reliable position detection, which is an advantage in many applications.

What types of absolute encoders are there?
There are various types of absolute encoders, including:
1. Absolute encoder: This type of encoder indicates the exact angle or position of the encoder in relation to a fixed reference point. Absolute rotary encoders can be available in various forms, such as optical rotary encoders, magnetic rotary encoders or potentiometric rotary encoders.
2. Single-turn encoder: This type of encoder indicates the absolute angle or position within a single rotation range. They provide a single position indication and are usually limited to a specific range of rotation.
3. Multi-turn encoder: In contrast to single-turn encoders, multi-turn encoders can detect several revolutions. They have additional mechanisms that make it possible to count the number of complete revolutions. This allows you to determine the absolute angle or position over several revolutions.
It is important to note that there are different technologies that can be used to implement these types of absolute encoders. These include optical sensors, magnetic sensors, potentiometric sensors and many others. Each technology has its own advantages and disadvantages and is suitable for different applications.

What is the typical resolution of absolute encoders?
The typical resolution of absolute encoders varies depending on the model and application. However, common resolutions can be between 10 and 16 bits. This means that the encoder is able to detect the position with an accuracy of 2^10 to 2^16 steps. With a 10-bit resolution, for example, this would be 1024 steps per revolution.
Which interfaces are used for rotary encoders, absolute?
With absolute encoders, various interfaces are used to read out the position information. Some of the most common interfaces for absolute encoders are:
1. SSI (Synchronous Serial Interface): SSI is a serial interface in which the position information is binary coded and transmitted. This interface is relatively simple and robust, but is usually only used for short transmission paths.
2. BISS (Binary Serial Synchronous): BiSS is an advanced version of SSI that enables a higher data transfer rate. It is also a serial interface in which the position information is transmitted in binary code.
3. EnDat: EnDat is a serial interface developed by HEIDENHAIN. It not only enables the transmission of absolute position information, but also other data such as diagnostic information. EnDat offers a high data transmission rate and is frequently used in industrial applications.
4. Profibus: Profibus is a widely used field bus system that can also be used to transmit position information for absolute encoders. It enables communication between encoders and other devices in the network.
5. EtherCAT: EtherCAT is a real-time Ethernet communication technology that can also be used to transmit position information for encoders. EtherCAT offers a high data transfer rate and is primarily used in industrial automation systems.
