Product details

What this motor is on the line

The 1FK7042-5AF71-1FG2 is a Siemens 1FK7 compact synchronous servo motor in the Servo Motors category, built for high-dynamic positioning and indexing axes paired with a Siemens SINAMICS drive on the same control platform.

Sourcing an EOL 1FK7 against the maintenance backlog

Because the 1FK7042-5AF71-1FG2 is flagged EOL, the procurement question is no longer "place a new factory order" but "do we have a confirmed-quantity lot, and is there a successor on the same frame" — the right move is to keep this code in the storeroom for spot replacement and only commit a redesign when the surplus channel dries up.

Frequently asked questions

Will the 1FK7042-5AF71-1FG2 drop into a panel that was specified around the 1FK7042-5AF71-1DB0?

Both are 1FK7 compact synchronous motors from the same frame family, but the 1FK7042-5AF71-1FG2 is 4.54 kg while the 1FK7042-5AF71-1DB0 is recorded at 5.44 kg — shafts, resolver/encoder feedback and connector variant differ across the 1FK7 order-code suffixes, so the panel/load fit has to be verified against the full suffix string before swapping without rewiring.
