The 6SL3520-2XB00-7AF0 is the SINAMICS G115D wall-mounted distributed drive at 0.75 kW in the FSA frame, using the B-connector interface (Q4/2 motor connector + 7/8" power connector) with PROFINET and EtherNet/IP communication. Rated at 2.2 A HO (4.4 A overload for 3 s), it is designed for direct machine-frame or motor-housing mounting on horizontal conveyor applications.

B-Connector — What Makes It Different?

The 2XB00 variant uses the B-connector system — Q4/2 connector for the motor cable and 7/8" connector for the 3 AC supply. Unlike C-connector or D-connector variants, the B-connector provides a robust mechanical interface optimized for conveyor environments where cables are subjected to vibration and frequent washdown. Electrically, the 0.75 kW FSA drive is identical across connector systems — same 2.2 A HO rated output, same 380 × 156 × 129 mm fanless enclosure, same integrated C2 EMC filter and braking chopper. The AF0 communication interface provides PROFINET IO with PROFIsafe and EtherNet/IP via M12 D-coded connectors with an integrated 2-port switch for daisy-chain line topologies.

0.75 kW FSA — The Mid-Range Fanless Option

Within the G115D FSA frame, the 0.75 kW rating sits between 0.55 kW and 1.1 kW — driving a moderate conveyor zone motor with 2.2 A HO output from a 380 × 156 × 129 mm natural-convection-cooled enclosure. The drive draws 290 mA from the 24 V DC control supply for the PROFINET interface. Direct machine-frame mounting eliminates the control cabinet, and the SD card slot enables fast parameter cloning across multiple drives on the same conveyor line.
