text: <s>[INST] E14 on Ultra 3000 What can cause an E14 error code on an Ultra 3000 drive? I am using Contrologix with 1756-M08SE with 5 nodes - 5th node was found with E14 but no faults were indicated in RSLogix. It's like the SERCOS ring was locked up. Integrator had programmed a waiting for startup amplifier message which was displayed for all 5 nodes. Cycled the DC power to the drive and all is OK. [/INST] You may find informations for this error inside Aid 29241. Yes, the technote indicate it as a Devicenet error... prior to the release of Ultra 3000 with SERCOS, the error was only associated with the Ultra 3000 with DeviceNet, BUT as the base U3K drive is the same platform with the addition of EITHER DeviceNet daughter PCB OR SERCOS daughter PCB, the fault code is valid for both. :smileysurprised: Here also some other indications... Problem: Ultra 3000 SERCOS in error with E14 fault Cause: 1. Poor connection between Drive and Communication Daughter PCB 2. Noise ingress to Auxiliary 5V supply (if Micro-Drive i.e. 2098-DSD-005-SE, 010-SE, 020-SE) Cure: 1. No action - Return for repair with detailed fault description. 2. Apply correct design procedures as described in manual GMC-RM001A-EN-P -- System Design for the Control of Electrical Noise Prevention: 1. N/A 2. Good installation practice. - fuzzy logic \\n </s>
