text: <s>[INST] Feedback only axis using a CLX SERCOS module Hello, The setup is a CLX processor with a 3 axis SERCOS module controlling one U3K axis. I now need to bring in an encoder as a Feedback Only axis. What's the best way? Any way of getting it onto the SERCOS module. Thanks [/INST] http://literature.rockwellautomation.com/idc/groups/literature/documents/in/2090-in007_-en-p.pdf The link above is for the 2090-U3BB2-DM44 connector. This connector fits on CN1 of your U3k drive. The manual shows inputs on pins 1 through 9 of CN1 for a 5V external auxiliary encoder. As you set up the feedback-only axis in the Motion Group, the GENERAL tab of the AXIS PROPERTIES for the feedback-only axis must have the U3k drive set in the ASSOCIATED AXIS section. You will also fill out the data in the AUXILIARY FEEDBACK tab, not the MOTOR FEEDBACK tab for the feedback-only axis. \\n </s>
