text: <s>[INST] Tuning out the noise on 2098-dsd-010x I had two servo drives installed on the same machine to replace an air cylinder and a stepper motor assembly. The Servo Controllers are 2098-dsd-010x and they were connected to TLY A230THJ62AA series servo motors. With one servo motor installed and running everything ran perfect.When the second Servo controller and motor were installed I could see blips on the I/O connections to the SLC 5/04 PLC. The Vendor that was assisting us in this conversion tried a couple of things that didn't work and then made a phone call and came back and adjusted the tuning feature in the Ultraware Software program, which eliminated the blips on the I/O.I now have four more machines to convert and was hoping someone could point me to a technote or had some tips to offer on tuning these controllers to eliminate the noise so there are no hiccups or intermittent problems with the I/O. TIA Jim [/INST] Sounds like your vendor did a little hand waving... I haven't had any experiences (with any brand or model) such that motor tuning affected I/O cabling. Generally, these problems are associated with wiring routing, grounding/shielding termination or other basic installation practices that were skipped or installed poorly. All communication or intermittent I/O problems I have had, have always been traced to installation problem, or field failures (i.e. worn out cables etc.). Don't be supprised if the problem shows back up. \\n </s>
