althfell Posted April 8, 2014 Report Share Posted April 8, 2014 i configure the plc and works ok with a 500 p/r encoder. when i connect a 1000 p/r doesn.t read anything. i can see only "0" why ? i configured as x 2 and X 4 and the same. the encoder is an incremental encoder from omrom(E6B2-CWZ6C) 1000 P/R Quote Link to comment Share on other sites More sharing options...
AlexUT Posted April 8, 2014 Report Share Posted April 8, 2014 Hi, What is rotation speed of encoder in your tests (PPR*(RPM)/60)? BR Quote Link to comment Share on other sites More sharing options...

AlexUT Posted April 8, 2014 Report Share Posted April 8, 2014 Following is a link to encoder site http://www.ia.omron.com/product/item/e6b27057d/index.html See "Output circuit diagram" section. It show NPN output. So you should use NPN input at PLC. And it should work. Please test and tell us if this works. Quote Link to comment Share on other sites More sharing options...
