The SINAMICS G115D 6SL3520-2XA21-5AA0 is a 1.5 kW wall-mounted distributed drive in the compact FSA frame with basic I/O (AA0 suffix). It is designed for light horizontal conveyor sections — roller beds, belt conveyors, and transfer stations in intralogistics and packaging lines. The FSA frame (380 × 156 × 129 mm) is the smallest G115D enclosure, suited to conveyor zones with tight mounting clearances. Natural convection cooling and IP65/IP66 protection enable maintenance-free, cabinet-free installation.

How does the AA0 differ from the AF0 at 1.5 kW?

Both variants share the same 1.5 kW power rating, FSA frame, and all hardware specifications. The AA0 provides basic digital and analog I/O — sufficient for conveyor zones where the drive receives discrete start/stop and speed reference signals. The AF0 upgrades to PROFINET with PROFIsafe for networked operation. For simple roller bed sections with local control, the AA0 provides the same drive performance at a lower interface cost.
