How to Count Encoder Pulses and Feedback for PLC Programming
Actually encoder on the shaft, you want to know their position, or mounted to monitor its value. Encoders have a few strokes, and they are therefore the number of pulses in one revolution.
Remark : - The coupling of the shaft encoder for precise measurement would otherwise reduce efficiency, and can destroy even be executed.
PLC-Logic Development: -
Now you will see step by step closer to producing the PLC program.
First you need the condition that when the countdown to begin, such as the pulses are counted when deciding if an encoder. In general, you want the auto to start cycle, so here you are given the state of the auto bit ok, but can be made on the application requirements.
I have here an example of Omron PLC CP1H, each PLC has a tutorial for the enumeration of the high speed pules, Omron, it is PRV, PRV we write instruction.
In PRV, we need the port number where we are the encoder and the corresponding control data to define.
Then, the value (number of encoder lines value) will appear in a forthcoming data from the PLC registers. (more…)
