The 6SL3520-0XB04-0AA0 delivers 4 kW in FSB fan-cooled frame (425 × 180 × 169 mm, 7.52 kg) with B-connector, integrated cooling fan, and AA0 I/O Control — basic terminal-based control for standalone conveyor sections. Rated for 10.2 A continuous output (HO) at 380–480 V three-phase, the first G115D power level requiring fan cooling. Compatible with IE2/IE3/IE4 motors across 0–550 Hz, IP65 sealed.

When does AA0 I/O Control make sense at 4 kW?

At 4 kW — a substantial conveyor section or medium-duty material-handling drive — AA0 I/O Control is the right choice when the drive operates as a standalone unit with simple control logic: start/stop from a local pushbutton or basic PLC digital output, speed reference from a potentiometer or analog output. No PROFINET controller, no network topology to plan, no GSDML file. The drive's power stage, frame, and motor compatibility are identical to the AF0 PROFINET variant. For a conveyor section that runs at a fixed or locally-adjusted speed and does not report diagnostics to a central system, AA0 provides the simplest path to commissioning with the same 10.2 A HO capability.
