What the part is on the bench
The 1FK7032-5AK71-1LG3: It belongs to the Motors > Servo Motors category — the class of part that closes the position loop downstream of a drive controller, not a standalone VFD-driven induction motor.
Lifecycle read for the BOM
For a robotics cell or a pick-and-place line where this exact frame is already designed in, that timing matters: the BOM line should be reconciled against the phase-out window before the next scheduled rebuild, and any spare stock earmarked for a hot-swap needs to be tagged with the current build date so you know how much shelf life is left. No official successor or cross-reference is on the ledger for this code — substitution has to be confirmed against Siemens documentation, not inferred from the part number suffix alone. Sourcing posture for an EOL-hot servo like this runs through independent distribution: each RFQ is quoted against the BOM quantity with the lot trace and current availability confirmed at quote time, not against a factory production schedule.
Integrator notes for an axis swap
The replacement sequence on a cell is nameplate-first: capture the encoder type, brake option, and shaft keying from the physical label on the failing unit before pulling it off the coupling, because the 1FK7 dash codes differentiate resolver vs multi-turn absolute encoder and presence/absence of holding brake.
