Encoder Installation: Connecting Absolute Encoders to PLCs
As we know, absolute encoder encoder is a kind of rotary measurement device, it will be measured by the angular displacement directly into a digital signal. Therefore, we will be in the application of the rotary encoder output pulse signal directly into the PLC, the use of high-speed counter on the PLC pulse signal counting, in order to obtain the measurement results. It is important to note that the number of phases of the rotary encoder outputs is different for different models of rotary encoders! Some rotary encoders output A, B, Z three-phase pulses, some have only two phases, A and B, and the simplest has only A phase. Encoder mounting high-speed end mounting can fully use the full range and improve the resolution. Tie rope displacement sensor is a linear displacement sensor in the structure of the delicate composition, fully combines the advantages of the angle sensor and linear displacement sensor, to become a small installation size, compact structure, large measuring stroke, high precision sensors, the stroke from a few hundred millimeters to more than a dozen meters ranging. Application we will...
