The 6SL3520-1XK00-3AF0 is the smallest drive in the entire G115D 1XK wide-voltage series: 0.37 kW at 1.3 A continuous output, PROFINET PROFIdrive interface, FSA frame. At the absolute entry point of the G115D power range, this drive runs the smallest actuation points on a decentralized machine — a singulation roller, a label applicator feed, a small divert gate — where the mechanical power requirement is minimal but full network integration is still required for coordinated line control.

PROFINET at 0.37 kW — why the smallest station still needs network visibility

On a packaging or assembly line, losing the 0.37 kW singulation roller without an immediate fault telegram creates the same cascade risk as losing a main drive: upstream product keeps feeding, a jam forms, and production stops for a manual clear. The AF0 interface reports the fault in the same PROFINET cycle as every other drive on the line — the PLC stops the infeed instantly. The cost to put PROFINET on the smallest drive is a one-time BOM increment; the cost of one unplanned line stop from a blind station is recurring and unbounded. For lines where every station is networked, the 0.37 kW AF0 enables true 100% drive visibility without a gap at the low-power end.
