The 1FK7042-5AF71-1FA5: Servo motors in this class are the actuator side of a closed-loop drive system — paired with a SINAMICS or similar servo controller, the resolver or encoder feedback closes position and velocity loops that a VFD alone cannot hold to the tolerance a packaging, indexing, or pick-and-place axis demands.
We source the 1FK7042-5AF71-1FA5 through independent industrial-automation distribution and quote against the BOM line on an RFQ — lead time and pricing are confirmed at quote, with availability checked against current independent-channel stock.
Not by weight alone — the two share the 1FK7042-5AF71-1xx base but the 1DB0 variant weighs 5.54 kg versus 4.54 kg here, which points to a different stack length or feedback option. Mechanical fit usually carries across the frame, but the controller's motor identification and feedback parameters need a nameplate cross-check before commissioning.
