What this servo is and where it lands
The 1FK7034-5AK71-1VB0: Lifecycle is the gating fact: the part is tagged EOL hot, which puts it squarely in the last-time-buy / surplus-broker window — a fresh factory channel quote is not the default, and the procurement decision usually hinges on date-coded stock and unit-level trace.
Field-side handling and fit notes
Servos in this frame typically run on a matched SINAMICS S120 drive; before swapping a hot-EOL unit on a running line, confirm the drive's firmware accepts the replacement motor's electronic nameplate so commissioning does not stall on F0139 encoder-init faults.
