The SINAMICS G115D 6SL3520-2XA21-5AF0 is a 1.5 kW wall-mounted distributed drive in the compact FSA frame, configured with PROFINET and PROFIsafe communication (AF0 suffix). It is the entry point to PROFINET-enabled distributed drive technology for light horizontal conveyor sections — roller beds, belt conveyors, and transfer stations in intralogistics and packaging lines. IP65/IP66 protection enables direct machine-mounted installation without a control cabinet.

How does the FSA frame compare to the FSB frame?

The FSA frame measures 380 × 156 × 129 mm (W × H × D) — narrower, shorter, and shallower than the FSB frame (425 × 180 × 134 mm). It houses the 0.37 to 1.5 kW power range in the smallest G115D enclosure, making it suitable for conveyor zones with tight mounting clearances. Like all G115D 2XA variants, the FSA frame includes an integrated C2 EMC filter and braking chopper as standard, and shares the same IP65/IP66 protection rating.
