4.54 kg synchronous servo, 1FK7 short stack
The 1FK7042-5AF71-1FH0-Z is a Siemens 1FK7-series synchronous servo motor cataloged under Servo Motors, with the -Z option suffix on the order code indicating a customer-specific configuration that drops into a SIMOTION or SINAMICS drive line.
EOL hot — what stops and what does not
For a maintenance spare on a running line this is the textbook eol_hot play: pin the exact nameplate option string to the order, source through independent channels with full traceability, and budget a verification cycle on the drive commissioning screen before trusting the replacement in production.
Sourcing posture for an eol_hot servo
No stock count, lead-time number, or immediacy promise — the eol_hot status means lot depth is the variable that decides every order. Buyers running a live line should send the full Siemens order string (including the -Z option suffix) and the nameplate photo with the RFQ so the channel can match the configuration exactly rather than substitute a same-frame variant that fails the encoder or brake check at commissioning.
