AS-Interface segments are limited by node count and trunk length, not by power — which makes the 2XH60-5AA0 build of the SINAMICS G115D a natural fit: 0.55 kW of belt control at 1.7 A rated (LO), hanging on the conveyor frame as one more address on the two-wire trunk that already runs the section.

Why does 0.55 kW suit the AS-i architecture so well?

Because the architecture rewards spreading drives out, and small drives spread furthest. One drive per section at 0.55 kW keeps the mechanical design simple — no shaft couplings over long distances, no central drive bank — while the integrated 24 V PSU and gland wiring remove the last reasons to open a cabinet. The IP65/66 / UL Type 4X housing with natural convection cooling sits wherever the belt is, and 200%/3 s starting headroom covers loaded belt starts at this rating.

How does it behave on a crowded trunk?

As a standard AS-i slave it draws its control data on the normal cyclic scan, so adding sections is a matter of addresses, not engineering. The trunk carries actuation and diagnostics; if a section later needs plant-network visibility, the same housing exists as the 5AF0 build with PROFINET and EtherNet/IP onboard — the 1.7/3.4 A ratings and the 380 x 216 x 129 mm dimensions do not move between the two order numbers, and neither does the mounting drill pattern.
