An incremental rotary encoder example for Omron

Hi.

I'm a begginer with the PLC staff. Could you please show me an example program /with a scheme/ for a simple project using a rotary encoder. I'm using Omron CPM2A and CJ1M. I found some good projects on http://www.mikroelektronika.co.yu/english/product/books/PLCbook/chapter7/chapter7a.htm but there is no example with encoders.

Thanx in advance.

I would suggest to you have a go yourself and then post what you have done here and all will help you.

The wires goes to the Inputs 3,4 and 5. A,B and Z. Then the value will be available @ 230+1. That's for starters. I'm not one to explain things very good but, ya, thats a begining. You also have to set the PLC up so that the High Speed Counter is enabled.

If You use CX programmr go to setting and enalbe the high speed counter.and download the setting to the plc.

Welcome Boyko!

I have to agree with BobB on this. If you go to the Omron Knowledge Center, www.knowledge.omron.com and download the Programming Manual for the CPM2 Manual Number W353, Section 2-2 gives a very good explanation of the high speed counter function and setup for your plc.

You will need to enable the high speed counter function in the plc setup as mentioned in the other posts.

Take a shot at it, then post if you have any questions.

Try this link to MrPLC.com Page 43 of the file has info on high speed counters used with encoders. If the link does not work, goto MrPLC.com, downloads, Omron, "CJ1M Motion + Interupts"
