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.
Incremental rotary 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 is defined as the incremental rotary encoder shaft encoder clockwise when looking for forward, A leading B for 90 & deg;
, on the other hand counterclockwise for reverse B ahead of A 90 & deg;
Also has not the same, want to see the product description.
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.
Suggest B pulse do consequent (
Do the reverse pulse, A pulse (
Pulse, Z origin zero pulse.
Set up counting the stack in the electronic device.
