Encoder how to judge whether a yo-yo

Rotary encoder, the application of the circuit is mainly use the encoder pulse recognition using single chip microcomputer. Basically is to see A, B phase difference, is A leading B or lag? Used to determine the encoder is forward or reverse? This is the direction of rotary encoder through identification circuit application. Today, the electronic will tell you something about how to use the encoder to judge forward or reverse? Method is easy to learn, you take a few seconds, good look for your work will be of great help! First of all, through the PLC is used to identify the direction of the counter. With high speed counter in PLC, can be set to a variety of patterns, including AB orthogonal pulse, we can according to the number of counters is thus to judge direction, increase or decrease some instruction of PLC has a judge speed, so that you can directly determine positive and negative turn! So we can judge from the hardware. Only need to choose the model A, B phase orthogonal mode can! When the HC0 current value increase turns out to be 90 degrees, A former XiangChao B phase to determine the encoder is forward or reverse, and through the pulse number to determine how many circuits of the encoder? Such a simple and practical method you learned? Shanghai electronic products specializing in the production of rotary encoder, 25 years, products with complete kinds, encoder industry took the lead through TS16949 ISO9001 ISO14001 quality certification, safe and reliable quality, trustworthy, looking for a rotary encoder electronics manufacturer is looking for Shanghai.
