How to use value-added encoder

Should pay attention to the three parameters：  
1. Mechanical installation dimensions, including positioning stop, shaft diameter, mounting hole position; cable outlet mode; installation space volume; working environment protection level meets requirements。  
2. Resolution, that is, the number of pulses output per revolution of the encoder, whether it meets the design accuracy requirements。  
3. Electrical interface, encoder output mode commonly has push-pull output (F-type HTL format), voltage output (E), open collector (C, common C is NPN-type tube output, C2 is PNP-type tube output), long-line driver Output. Its output should match the interface circuit of its control system。 



Ask how to use incremental encoders：
1. Incremental rotary encoder has resolution difference, which is measured by the number of pulses generated per revolution. The number is from 6 to 5400 or higher. The more the number of pulses, the higher the resolution; this is an important basis for selection. one。     
2. Incremental encoder usually has three signal outputs (differential six signals): A, B and Z, generally adopt TTL level, A pulse is in front, B pulse is in the rear, A and B pulses are 90 degrees apart, each The circle emits a Z pulse that can be used as a reference mechanical zero. Generally, the A-pre-B or B-pre-A is used for the judgment. The incremental encoder is defined as the shaft end seeing the encoder rotates clockwise to the forward rotation, the A-pre-B is 90°, and the counterclockwise rotation is the reverse B-pre-A. 90°. There are also different, depending on the product description。     
3. Use PLC to collect data, you can use high-speed counting module; use industrial computer to collect data, you can use high-speed counting board; use MCU to collect data, it is recommended to use input port with optocoupler。     
4. It is recommended that the B pulse be a forward (forward) pulse, the A pulse be a reverse (backward) pulse, and the Z origin zero pulse.。     

5. Setting up a counting stack in an electronic device。
