The Siemens 6SL3520-1XC01-1AF0 is the PROFINET/EtherNet/IP communication variant in the 1XC connector system of the SINAMICS G115D wall-mounted distributed drive family, rated at 1.1 kW in the FSA frame (380 × 156 × 129 mm). With 3.1 A rated output (High Overload), 380–480 V 3-phase supply, C-type connector, and integrated PROFIsafe SIL 2 safety, it serves light conveyor sections — small belt turns, diverters, singulation gates — in facilities using C-connector cable sets. Electrically identical to the 0XC01-1AF0; the 1XC designation is the "1X"-prefix C-connector catalog path.

The drive supports IE3 asynchronous motors, IE4 synchronous reluctance motors, and SIMOGEAR geared motor combinations up to 1.1 kW. Control modes: V/f (0–550 Hz), V/f with FCC, sensorless vector control (0–240 Hz). Pulse frequency: 4–16 kHz. Integrated 180 V DC brake control. The integrated 2-port PROFINET switch supports daisy-chain line topology.
