The 6SL3520-0XB40-3AB0 is the entry-level B-connector SINAMICS G115D with AB0 Standard I/O — 0.37 kW in the compact FSA frame (380 × 156 × 129 mm, natural convection). Rated for 1.3 A continuous output (HO) at 380–480 V three-phase, it serves the smallest conveyor zone applications with hardwired terminal control — no PROFINET infrastructure required. Compatible with IE2/IE3/IE4 motors across 0–550 Hz, IP65 sealed.

Why choose Standard I/O for such a small drive?

At 0.37 kW — typically the lightest conveyor zones with small motor loads — the application is often a simple start/stop and fixed-speed section. AB0 Standard I/O eliminates all network configuration: no PROFINET controller, no GSDML file, no topology planning. The drive receives start/stop and speed reference directly from digital and analog terminals. This keeps the electrical design simple and commissioning straightforward — wire the terminals, set the parameters via the local interface or SD card, and the zone runs. If the section later integrates into a plant-wide network, the AF0 variant (0XB40-3AF0) provides the same hardware with PROFINET onboard — both share identical FSA frame, B-connector, and 1.3 A HO power stage.
