For a buyer this shifts the procurement posture from a quoted production-line delivery to a lot-and-trace buy — each unit has to be qualified on incoming inspection against the nameplate, and lead time is dictated by what the independent channel can locate, not by a factory schedule. ## Field-side realities of an EOL servo swap A commissioning engineer pulling this code out of the surplus channel needs to verify the encoder variant and the option suffix (-Z+Q31) against the original BOM before mounting — the 1FK7 family shares the same frame across resolver, absolute, and multi-turn encoder configurations, and a swapped encoder protocol will throw a drive-side F-code at first commissioning.","metaTitle":"Siemens 1FK7042-2AK71-1CH1-Z+Q31 Servo Motor, EOL","metaDescription":"Siemens 1FK7042-2AK71-1CH1-Z+Q31 compact synchronous servo, 2.25 kg, EOL lifecycle.
