Where it sits on the line
The Siemens 1FK7042-5AF71-1FG3-Z V42 is a 1FK7 COMPACT synchronous servo motor in the 3.0 Nm torque class, built around the standard incremental encoder/resolver interface used across the 1FK7 generation on SINAMICS S120 drive platforms. Servo motors of this class are bolted onto the back of a gearbox or directly to the load shaft and driven from a cabinet-mounted S120 power module — a line-down failure on a packaging, converting, or machine-tool axis is the usual reason a buyer is hunting this exact code.
Sourcing posture on a flagged-EOL motor
For an MRO storeroom, that means stocking this code now as a hot spare rather than relying on a future OEM reorder window — quote the quantity you want to carry and lock it in.
