The 1FK7 series is the compact, naturally cooled or fan-cooled synchronous servo platform Siemens has shipped into SINAMICS S120 drive cabinets for over a decade, so the motor matches the standard 1FK7 shaft and connector footprint — important when you're trying to drop a replacement onto an existing machine axis without a mechanical rework. For a buyer, the practical so-what is that 28 Nm at 3000 rpm is the continuous operating envelope — short-term peak torque is higher, but every cycle above the rated figure pulls heat out of the windings and either shortens service life or forces a derate on the next axis over. The mechanical output figure (3.77 kW) is what the line-protection breaker and cable sizing should be calculated against, not the peak transient. The line is flagged EOL hot — Siemens has moved the 1FK70867AF711FG3 out of broad distribution but hasn't pulled the rug entirely: the part still shows up in live spare-parts pipelines and independent channels while residual stock clears. No official second-source or pin-compatible successor appears in the ledger for this exact order code, so a like-for-like swap has to come from the same SIMOTICS 1FK7 family with the matching winding code — and that's where a value-engineering buyer should push back on list price, because the BOM doesn't care about a successor that needs a different shaft or feedback connector. For an MRO planner running a line that won't tolerate a half-day changeover, the practical move is to lock in a spare before the residual stock bleeds out — once independent inventory is gone, you're into lead-time purgatory on a motor whose encoder alignment has to match the SINAMICS S120 commissioning file on the drive. If you're rationalising the SKU across a fleet, confirm the winding letter and feedback type against the nameplate on the existing motor before issuing the PO; the 1FK7 family shares a frame but not every variant uses the same encoder resolution. ## Sourcing posture for a hot-EOL Siemens servo For a controls-integrator that needs the motor on a specific outage window, the smarter move is to specify the winding code and resolver/encoder type on the RFQ alongside the order code so the supplied unit drops straight onto the SINAMICS topology without re-commissioning.","metaTitle":"Siemens 1FK70867AF711FG3 Servo Motor, EOL hot stock","metaDescription":"Siemens 1FK70867AF711FG3 28 Nm synchronous servo motor, 3.77 kW at 3000 rpm.
