Starting with basic things, all encoders are divided into 2 categoria. Then, impulses are transmitted to the drive to provide decoded information quickly and precisely. Each encoder gets a certain number of impulses that are decoded into the parameter of a motor movement. Nevertheless, which type of encoder do you intend to use, it is necessary to know what type of encoder signals does it provide. They are based on one of the following principles: either magnetic principle or optical one. What Is Encoder and Why Its Signal Type Is so Important?Įncoders are sensors that help in positioning moving parts of a motor or rotary elements of each industrial system. As there are lots of options among various encoders starting from their signal type and ending with constructive peculiarities, it is necessary to get through them to be sure you are choosing the right option for your industrial system's goals. Due to it, all the further data implementation depends. When we talk about encoder's construction and working principle, one of the basic characteristics that always matter is the encoder output signal. The typical and least expensive solution is to use a special encoder. To solve such a problem, it is necessary not only to accurately estimate the speed of movement of the aggregate units, but also to provide a linear characteristic for assessing the position of the mechanism in a wide range of speed variation.
A separate requirement regarding the operation of technological units is the optimization of the time of movement along a given trajectory. Avoiding errors requires reliable feedback, which is paramount to any technical challenge. This can result in a complex mechanism stopping. When adding elementary operations of movement, errors of each individual manipulation are included in the general task.
