What are the 4 common types of encoder market applications?

An encoder is a device that compiles and converts a signal (such as a bit stream) or data into a signal form 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. Encoders can be divided into contact type and non-contact type according to the reading mode; encoders can be divided into two types: incremental and absolute according to the working principle.

What are the 4 common types of encoder market applications? There are currently four common encoders on the market:

First; 2500 line square wave pulse ABZ (including inverted) and UVW (including inverted) commutation signal. Among them, the 2500-line square wave pulse signal can achieve the actual resolution of 10000/360 degrees through 4 times of frequency once. It is the position and speed loop corresponding to the motor control. UVW is the position conversion corresponding to the winding coil of the synchronous servo motor. There are 4 pairs of levels, 8 pairs of levels, other pairs, etc. The encoder has many output cores, including 2 power supplies, totaling 14 cores.

Second; line 2048 contains the sine and cosine signals of the opposite phase of AB and outputs the sine and cosine signals of the opposite phase of CD with a single rotation period. This requires the servo controller to receive the equipment to subdivide the sinusoidal signal to obtain higher resolution (AB) and single-rotation position (CD) controlled commutation.

The signal lines are A+A-, B+B-, C+C-, D+D-, and the power supply is positive and negative.

Third; the sine and cosine signal contained in the AB phase of the 2048 line plus the digital serial signal.

For example, in the initial hiperface1.0, the RS485 signal (RS485) obtains the position of the motor rotor coil UVW, and the incremental AB sinusoidal signal is selected when rotating, and the servo controller receives the sinusoidal signal to obtain higher resolution (for example, 10-bit fine Differentiation

Or similar Endat2.1, RS422 signal + AB sine and cosine, or SSI, RS422 signal + AB sine and cosine. What are the 4 common types of encoder market applications?

Fourth; the above 2 sinusoidal signals are subdivided inside the encoder and integrated into digital signals, or the 2 groups of signals in 3 are integrated into 1 set of serial digital signal output, providing 14 bits, 17 bits, 19 bits, 22 bits, 25-bit and other digital signals.

For example Endat2.2, Blss,

EtherCat (or other bus type, EtherCat signal), DSL, etc.

The 17-bit-25-bit (1 circle) resolution encoder mentioned above is not the accuracy of the encoder, but the resolution of the encoder. The same is the 17-bit encoder, and the possibility of different accuracy is very high.

For example, the 17-bit subdivision based on the principle of magnetoelectricity (referred to as 17-bit magnetic coding) is not about the 17-bit precision of an optical encoder disk. There are also many modes of magnetic coding, and their accuracy is quite different. This is because these high-resolution encoders are all high resolutions obtained by subdivision of the sinusoidal signal of the original signal. The accuracy of the encoder signal depends on the method of obtaining the original signal of the encoder, signal quality and system accuracy, and subdivision And the electronic error caused by compensation.
