How to use incremental encoder?

The working principle of incremental encoder is as follows: with the axis of rotation of uniform upon grating pulse encoder, evenly distributed on the encoder with a number of pervious to light shading section and section. Incremental encoder has no fixed starting zero, the output is the pulse is proportional to the Angle increment, counter has to be used to gauge the pulse number. Every turn a pervious to light zone, gives a pulse signal, the counter current value add 1, counting result corresponds to the Angle increment. Incremental encoder manufacturing process simple, cheap, sometimes also used to measure the absolute Angle. How to use incremental encoder? 1. Incremental rotary encoder resolution differences, using each lap measure, the number of pulses produced from 6 to 5400 or higher, pulse number, the more the higher the resolution; This is one of the important basis for selection. 2. Incremental encoder usually have three way signal output ( Difference have all signal) : A, B and Z, generally USES the TTL level, A pulse in the former, pulse in the B, A, B, pulse is 90 degrees, each lap sends A Z pulse, mechanical zero can be used as A reference. General use advanced B or lead to A, B but the specific situation to see whether the product description. 3. Using PLC to collect data, can choose high speed counting module; Using industrial computer data, can choose high speed counting board; Using single chip microcomputer to collect data, it is suggested that chooses input port with photoelectric coupler. 4. Suggest B pulse do consequent ( The forward) Do the reverse pulse, A pulse ( Backward) Pulse, Z origin zero pulse. 5. Set up counting the stack in the electronic device. Shanghai electronics is 27 years old coder manufacturer, specializing in the production of incremental encoder, absolute encoder. At home and abroad, rotary encoder type can be perfect to replace brand encoder, power encoder manufacturers, the factory has advanced production equipment and testing equipment, safe delivery with quality! Find the incremental encoder manufacturer is looking for electronic.
