The 6SL3520-1XL01-5AF0 is the 1.5 kW G115D in the FSA frame — the highest power rating in the most compact G115D enclosure before stepping up to the FSB frame at 2.2 kW. Delivering 4.1 A continuous with 8.2 A peak (200% for 3 seconds), it handles light-to-medium conveyor rollers, belt sections, and auxiliary drives in packaging and assembly lines. The AF suffix provides PROFINET communication for SIMATIC-controlled distributed networks. Unlike the 3-phase-only FSB models in the 1XL variant, the 1.5 kW FSA accepts both single and three-phase supply — flexibility for installations where three-phase is not available at every mounting point.

The FSA enclosure measures 380 × 216 × 129 mm — wall-mounted directly on the machine frame, no control cabinet. IP65 (connectors) / IP66 (cable glands) / UL Type 4X Indoor, operating from −30 to +40 °C. Standard G115D features include an integrated C2 EMC filter, internal braking resistor, STO SIL 2 via Profisafe, and SAM web-server commissioning. IE2/IE3 asynchronous and IE4 synchronous reluctance motors are supported with V/f or vector control from 0–550 Hz.
