The 6SL3520-1XK00-5AF0 is the smallest G115D in the 1XK wide-voltage series: 0.55 kW at 1.7 A continuous output, PROFINET PROFIdrive interface, FSA frame. At this power level, the drive typically runs a single short roller conveyor, a small belt section, or a packaging line auxiliary — applications where the mechanical load is low enough that 0.55 kW suffices, but the automation architecture demands network-level visibility at every actuation point.

The case for PROFINET at the smallest drive

On a packaging line with 40 drives, losing one 0.55 kW roller station without an immediate fault telegram can cascade: the upstream station doesn't stop, product accumulates, and a jam triggers a manual reset that costs 20 minutes of production. The AF0 PROFINET interface reports that fault in the same PLC scan cycle — the line controller stops the upstream station before product piles up. The cost increment of AF0 over AA0 at 0.55 kW is a fraction of the cost of one unplanned line stop. This is the logic that drives PROFINET adoption down to the smallest drive in the catalog.
