The listed lifecycle stage is eol_hot: Siemens has withdrawn the 1FK7 generation from new orders, so the procurement route for fresh BOM positions is independent distribution rather than factory-direct — quoted per RFQ against the specific shaft, brake, and encoder code embedded in the order string. ## What the 4.88 kg frame means on the install Because the 1FK7 is a feedback-driven motor, the encoder variant and connector keying are baked into the order suffix; quoting against the BOM must mirror the existing axis nameplate exactly, or the drive-side parameter set and resolver/encoder commissioning routine will need to be re-loaded.","metaTitle":"Siemens 1FK7042-5AF71-1FA0 Servo Motor, EOL, 4.88 kg","metaDescription":"Siemens 1FK7042-5AF71-1FA0 servo motor, lifecycle eol_hot.
