The SINAMICS G115D 6SL3520-1XB02-2AB0 is a 2.2 kW (3.0 hp) wall-mounted distributed drive with AS-Interface communication and an integrated operator panel. As the entry-level FSB-frame variant in the 1XB AS-i family, this drive bridges the gap between the compact FSA (up to 1.5 kW) and the higher-power FSB models (3–4 kW), delivering 5.9 A of continuous output current with 200% overload (11.8 A peak). The AB0 configuration adds the operator panel and 24 V DC backup power to the AS-i base, making it a practical choice for conveyor zones where on-machine diagnostics add operational value.

2.2 kW — The FSB Gateway. At 2.2 kW, the G115D transitions from the FSA frame (380 × 156 × 129 mm) to the FSB frame (425 × 180 × 134 mm) — a roughly 50% larger heatsink surface area that enables natural convection cooling at higher power levels. This power rating covers a critical sweet spot in conveyor applications: heavy-duty roller conveyors handling palletized goods, incline belt conveyors with moderate elevation, and merge tables where product accumulation creates variable loading. The 5.9 A output comfortably drives 2.2 kW SIMOGEAR geared motors with headroom for voltage drop on long cable runs typical of distributed architectures.

AB0 Panel — Diagnostic Value at Mid-Power. The integrated operator panel is particularly useful at the 2.2 kW level because these drives often sit in the middle of a conveyor topology — not at the head end where a control cabinet might be nearby, and not at the tail where loads are lightest. When a mid-zone drive faults, the operator must walk the length of the conveyor to locate the problem. The AB0 panel's fault display at the drive itself means the first responder who reaches the faulted zone can immediately read the fault code, check operating status, and attempt a local reset — without walking back for a laptop or calling the controls engineer.
