The SINAMICS G115D 6SL3520-2XA21-1AF0 is a 1.1 kW wall-mounted distributed drive in the compact FSA frame, configured with PROFINET and PROFIsafe communication (AF0 suffix). It is designed for the lightest horizontal conveyor sections — small roller beds, transfer stations, and diverters in intralogistics and packaging lines. The FSA frame (380 × 156 × 129 mm) is the smallest enclosure in the G115D range.

What does the AF0 suffix provide at the 1.1 kW level?

The AF0 suffix enables PROFINET industrial Ethernet with integrated PROFIsafe functional safety up to SIL 3, even at the smallest power rating. In a distributed conveyor architecture, this means even the lightest conveyor sections can participate in a fully networked, safety-integrated control system — daisy-chained via a single Ethernet cable carrying control, diagnostics, and safety signals. The 1.1 kW rating with 3.1 A HO rated output (6.2 A peak for 3 s) covers small motorized roller and belt sections.
