The Kinetix 5500 (2198-H070-ERS2) is showing an Absolute positioning error on my HMI for the machine and showing S47 FEEDBACK DEVICE FAILURE 66 on the drive display. We have replaced the motor (VPL-B1652F-PK12AA_KPL) and the cable (2090-CSBM1DF-14AF16) have been replaced. Any suggestions to try and troubleshoot the issue would be greatly appreciated. [/INST] Hello Joshua this is an internal error of the Encoder. The fault should come with a subCode 66 66 = Internal_Resource_Access_Error_Subcode What is the Firmware on the drive ? This issue could be solved by upgrading your drive FW to 2.008 or higher Please review this Rockwell Knowledge base article: https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/700900 regards \\n </s>
