Hello, I am having issues with reading the signal from an incremental encoder connected to an S7-1500 PLC. TIA version is 15.1. This is the data sheet of the encoder in question if any additional info is needed: SICK DFS60A-S4EC65536 Originally it was connected to a TM PosInput module 6ES7 551-1AB00-0AB0 but in that case the High Speed Counter technology module would give an error code for "incorrect encoder signal" that could not be acknowledged. I checked the manual for TM PosInput module and if I understood correctly it doesn't support HTL encoders. Can someone confirm is this correct? After that I tried to connect it to a TM Count module 6ES7 550-1AA00-0AB0. In the configuration settings I put "push-pull" under sensor type. After trying to turn the encoder by hand the counter value is changing, increasing in one direction and decreasing when turning the encoder in the other direction. But I still get the "incorrect encoder signal" error message from HSC technology module. I cannot find any additional info for possible causes and potential solutions. Wiring seems completely ok. I am only using the A and B signal wires, A/, B/, N and N/ are not connected to anything. Should I also use the N signal? Maybe add something to configuration of HSC on PLC? And also, the power supplied to the encoder is coming from an outside supply of 24 V, not from the TM Count module, I am unsure does that matter. Any help is much appreciated |
