What this motor is, and why the EOL flag drives the decision
The 1FK7040-5AK71-1DG2 is a Siemens servo motor from the 1FK7 compact series, listed in the SINAMICS S120 ecosystem as a feed and positioning axis for machine builders who pair it with a SINAMICS S120 drive line-up. Its lifecycle stage is recorded as eol_hot, which means the part is approaching end of production on Siemens' own schedule — the buying question shifts from stock-on-shelf to confirmed traceability and last-time-buy timing on the BOM line.
Handling, mounting and panel-side integration notes
As a SINAMICS S120 motor it expects the matched drive-side power and signal cable set; the encoder feedback, brake and power conductors land on the motor terminal box per the S120 wiring diagram, and the commutation is set automatically once the drive electronic nameplate is read from the motor.
Sourcing posture for an eol_hot servo motor
Because the part is flagged eol_hot, the cleanest move is to confirm the last-time-buy window against your remaining axis-quantity requirement before quoting — independent distribution can still pull traceable stock for service spares, but the BOM line should be frozen against whatever Siemens announces as the cut-off. We source the 1FK7040-5AK71-1DG2 to order against the RFQ: lead time, quantity breaks and a declaration-of-conformity pack are confirmed at quote time so the spares drawer, the retrofit job and the new build all hit the same audit trail.
