Line: One week engraved line of the encoder photoelectric encoder disc. The incremental encoder disc can be engraved with 10 lines, 100 lines, and 2500 lines, as long as the encoder disc can engrave them, you can choose any number; Due to the arrangement of the Gray code, the engraved lines on the code disk are basically power lines of 2, such as 256 lines, 1024 lines, 8192 lines, etc.

Bit: 2 to the power of n. Since the code wheel is often output as a power of 2 line, most code wheels are expressed as "bits". However, there are also special Gray Yu code outputs for code wheels, such as 360 line, 720 line, 3600 line, etc. Incremental value encoders are also represented by bits, such as 15 bit and 17 bit. They use internal subdivision to double the number of lines calculated, usually greater than 10000 lines, and are expressed as "bits".

Resolution: The angle that the encoder can resolve. For general calculations, it is calculated based on 360 degrees/number of lines. Currently, most of them are directly expressed in terms of how many lines. But this leads to some confusion of concepts, such as incremental value encoders, which can actually have a resolution of 360/10000 if they use four harmonics of A/B and 2500 lines. If the internal subdivision calculation can have more "lines", up to 15 bits and 17 bits, then incremental encoders often use "lines" to represent that there is no harmonic subdivision yet, and use "bits" to represent that it has already been subdivided.

Resolution: also known as bit count, pulse count, or several line system (this term is used in type encoders). For incremental encoders, it refers to the number of pulses output by the encoder after one rotation of the shaft; For a type encoder, it is equivalent to dividing a 360 ° circle into several parts. For example, if the resolution is 256P/R, it is equivalent to dividing a 360 ° circle into 256 parts, and outputting a code value for every rotation of about 1.4 °. The unit of resolution is P/R.

Incremental: There are two engraved lines in the encoder: A/B and Z, and the rotation angle is calculated by adding up the lines (increment). Some add U, V, and W. The encoder is divided into three zones by 120 degrees to determine the position, which is called a hybrid encoder. Some use internal subdivision circuits to improve the resolution of "lines", and express them using internal battery memory and "bits", often referred to interchangeably, but in reality they should be "lines".

Formula: The engraved lines inside the code wheel are n, with 2, 4, 8, 16... Arranging combinations, the readings are directly read from the disc using the "0" and "1" encoding method, rather than being accumulated, so they are not affected by power outages or interference. As for the increment, which resolution and accuracy are higher? If it is an actual code wheel engraving line, the code wheel resolution "number" can be twice that of the incremental code wheel. If it is a frequency doubling technology, the incremental value code wheel resolution "number" can be greater. However, please note that I am using "resolution number", which does not represent accuracy, because subdivision frequency doubling is an electrical simulation technology that does not improve accuracy. Accuracy is determined by the comprehensive factors of code wheel engraving line, mechanical installation of shaft, and electrical response. Overall, resolution can be achieved in increments, but accuracy is high because it is not affected by power outages, interference, speed, or electrical response. Especially when high precision and high speed are required, incremental subdivision cannot meet the requirements.

European market servo multi turn: resolution per turn: 11 bits is 2048; 12 bit 4096; The 13th digit (i.e. 2 to the power of 13) is 8192; 14 is 16384; 15 is 32768; 16 bits (i.e. 2 to the power of 16) is 65536; 17 digits 131072; 18 digits 262144; 19 positions 524288; 20 digits 1048576; ... 25th place 33554432 (German Heidelberg's lap can reach 25th place, domestic lap can reach 16th place). Continuous measurement cycles: Most have 12 bits of 4096, a few have 14 bits of 16384, and the total number of bits ranges from 25 to 37. (Currently, Heidelberg in Germany can provide a resolution and number of turns up to 37 bits; domestically produced 28 bit GEMPLE)

An encoder is a device that encodes and converts signals or data into a signal format that can be used for communication, transmission, and storage. The encoder converts angular displacement or linear displacement into electrical signals, the former is called a code wheel, and the latter is called a code ruler. According to the reading method, the encoder can be divided into two types: contact type and non-contact type. Contact type uses electric brush output, and one electric brush contacts the conductive or insulating area to indicate whether the code state is' 1 'or' 0 '; The non-contact receiving sensitive element is a photosensitive element or a magnetic sensitive element. When using a photosensitive element, the state of the code is represented by a transparent area and a non transparent area to indicate whether it is' 1 'or' 0 '. The collected physical signal is converted into a machine-readable electrical signal for communication, transmission, and storage through binary encoding of' 1 'and' 0 '.

effect

A measuring element that converts the relative displacement between two planar windings into an electrical signal using the principle of electromagnetic induction, used in length measurement tools. Induction synchronizers (commonly known as encoders or grating rulers) are divided into two types: linear and rotary. The former consists of a fixed ruler and a sliding ruler, used for measuring linear displacement; The latter consists of a stator and a rotor, used for measuring angular displacement. In 1957, R.W. Tripp and others in the United States obtained an induction synchronizer, originally known as a position measurement transformer. Induction synchronizer was its product name and was initially used for positioning and automatic tracking of radar antennas, as well as guidance. In mechanical manufacturing, induction synchronizers are commonly used in positioning feedback systems for digital control machine tools, machining centers, and measurement digital display systems for coordinate measuring machines, boring machines, etc. It has low requirements for environmental conditions and can work normally in environments with a small amount of dust and oil mist. The period of the continuous winding on the fixed length is 2 millimeters. There are two windings on the slide ruler, with the same period as on the fixed ruler, but offset by 1/4 period (with an electrical phase difference of 90 °). There are two working modes of induction synchronizers: phase detection and amplitude detection. The former is to input two AC voltages U1 and U2 with a phase difference of 90 ° and the same frequency and amplitude into the two windings on the slider. According to the principle of electromagnetic induction, the winding on the fixed length will generate an induced potential U. If the slider moves relative to the fixed length, the phase of U will change accordingly. After amplification, it can be compared, subdivided, and counted with U1 and U2 to obtain the displacement of the slider. In the amplitude discrimination type, the input to the slider winding is an AC voltage with the same frequency and phase but different amplitudes. The displacement of the slider can also be obtained based on the amplitude changes of the input and output voltages. The system composed of an induction synchronizer and electronic components such as amplification, shaping, phase comparison, subdivision, counting, and display is called an induction synchronizer measurement system. Its length measurement accuracy can reach 3 micrometers/1000 millimeters, and angle measurement accuracy can reach 1 ″/360 °.

incremental

An incremental encoder converts displacement into a periodic electrical signal, which is then converted into count pulses to represent the magnitude of displacement in terms of the number of pulses.

formula

Each position of the encoder corresponds to a specific digital code, so its indication is only related to the starting and ending positions of the measurement, and not to the intermediate process of the measurement. (REP)
