SIMOTICS S-1FK7 servo, Drive-CLiQ ready
The Siemens 1FK7040-2AK71-1DG0 is a SIMOTICS S-1FK7 series servo motor with a flange mounting footprint, rotatable power connector for cable-outlet flexibility, and a 22-bit incremental encoder (IC22DQ) delivered through a Drive-CLiQ interface — meaning it drops into the SINAMICS S120 family on a single hybrid cable and auto-identifies to the drive without parameter hand-entry.
Lifecycle: eol_hot — independent channel only
No official successor is named in the available record for this specific encoder-flange-power-connector variant; a 1FK7 series rebuild onto a different encoder option or a move to the 1FK2 successor family requires a Drive-CLiQ topology check and a SINAMICS firmware compatibility review before commissioning, because IC22DQ auto-parameterisation only works if the receiving drive slot supports that encoder profile. Replacement-spare buyers should treat this part as a last-time-buy candidate rather than a stocking line item — quote lead time and traceable-lot availability against the RFQ, and verify nameplate data against the purchase order before integration.
