The encoder resolution is the optical engraving of the encoder's code wheel. But now the encoder resolution in the market is dazzling, I don't know how to distinguish, so this article will address this doubt for you to answer in detail. Encoder resolution Encoder resolution refers to the minimum angular change that the encoder can read and output. If the encoder is a direct square wave output, she is the number of pulses per revolution (PPR), but if it is a sine and cosine model output, it can be electronically subdivided by the signal analog quantity to obtain more square wave pulse PPR output. The square wave output of the encoder has phase A and phase B, and phase A and phase B are 1/4 pulse period apart. By the judgment of the rising edge and the falling edge, the variation step of 1/4 pulse period can be obtained (4 times frequency ), this is the minimum measurement step (Step), so strictly speaking, the minimum measurement step is the resolution of the encoder. The resolution of the rotary encoder can be expressed by "line line", the number of pulses per revolution PPR, or "step step". The parameter of the incremental encoder resolution is PPR, that is, the number of pulses per revolution, for example, 360 lines per circle, A, B outputs 360 pulses per revolution, and the resolution parameter is 360PPR. Judging the encoder resolution through the above can be understood, more information about the encoder, please continue to pay attention to the hot security investment network.
