Incremental rotary encoder has a resolution of differences, using the number of pulses per revolution generated to measure the number from 6-5400 or higher, the more the number of pulses, the higher the resolution; this is an important basis for selection .
Incremental rotary encoders usually have three-way signal outputs (differential six signals): A, B and Z, the general use of TTL level, A pulse front, B pulse after, A, B pulse phase difference of 90 degrees, each ring issue a Z pulse can be used as a reference mechanical zero. A general use leads B or B leads A to be sentenced, I incremental rotary encoder is defined as the encoder shaft clockwise to look forward, ahead of A and B is 90 °, counterclockwise rotation and vice versa for the reverse B A lead of 90 °. There are not the same, depending on the product description.
Use PLC gathering data, the choice of high-speed counting module; use the IPC data acquisition, high-speed counting cards can be used; the use of SCM data acquisition, we recommend the use of optical input port coupler.
Proposal B pulses do forward (forward) pulse, A pulse to do the reverse (backward) pulse, Z datum zero pulse.
Stack establishment count in the electronic device.
