How to use incremental encoder?

Type 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.

Type 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. Generally use A forward B or B ahead of A sentence to, my company the incremental encoder is defined as the shaft end see encoder clockwise as A forward, A leading B is 90 °, on the other hand counterclockwise for reverse B ahead of A 90 °. Also has not the same, want to see the product description.

3, the use of 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, it is recommended that the consequent pulse do B (forward) pulse, A pulse reverse (backward) pulse, Z origin zero pulse.

5, set up counting the stack in the electronic device.
