What the 5.76 kg frame means on the bench
The 1FK70635AF711FA0: The 1FK7 series is the Siemens synchronous servo line driven from a SINAMICS S120 or similar drive; commissioning checks on a replacement unit focus on encoder alignment, holding-brake release voltage, and resolver/EnDat parameter slot, not on the motor's basic dimensions which are fixed for the frame.
Sourcing posture for an eol_hot 1FK7
Because the part is flagged eol_hot, the realistic ask is independent-channel stock and lot-traceable surplus — every quote should be returned against an RFQ naming the quantity, the encoder variant, and the brake option, since those suffix digits vary across the surviving inventory.
