As a synchronous servo it expects a sinusoidal-commutated drive with a position feedback channel (resolver or absolute encoder, per the variant suffix); pairing it with the matching SINAMICS drive closes the current loop at the motor and lets the controller command torque directly in Nm rather than inferring it from current. ## Lifecycle stage — EOL/hot and what it means For a buyer this shifts the sourcing question from catalogue to detective: the lot traceability, encoder variant in the suffix, and shaft/keyway revision have to be confirmed against the BOM before the part ships, because a half-turn difference in feedback resolution on a 1FK7 can turn a drop-in replacement into a commissioning weekend. ## Sourcing posture for a hot-EOL servo Quotations are built per RFQ against this order code: confirm current availability, warranty terms, and lead time at quote time, and request the manufacturer's Certificate of Origin if the build is shipping into a regulated line.","metaTitle":"Siemens 1FK71055AF711UG3 Servo Motor, 48 Nm, 8.17 kW","metaDescription":"Siemens 1FK71055AF711UG3 synchronous servo motor, 48 Nm, 8.17 kW, 3000 rpm, EOL/hot lifecycle.
