The 6SL3520-1XL01-5AB0 is the 1.5 kW variant in the G115D FSA frame with the 1XL enclosure — the highest power rating available in FSA. Delivering 4.1 A continuous (8.2 A peak at 200% overload), it handles light conveyor sections, roller beds, and pick-and-place stations within the compact FSA footprint. The 1XL variant uses a taller enclosure (216 mm vs 156 mm on 1XK) to accommodate additional integrated options while keeping the same 380 mm width and 129 mm depth.

The AB suffix denotes the enhanced I/O configuration — more digital and analog I/O channels, an additional safe torque off (STO) interface, and expanded connectivity compared to the AA-suffix base variant. Mounted directly on the machine frame, the FSA enclosure eliminates the need for a control cabinet. IP65 protection with connectors (IP66 with cable glands) and UL Type 4X indoor rating suit washdown and dusty environments. Standard features include an integrated C2 EMC filter, internal braking chopper, STO SIL 2 via terminals, and SAM web-server commissioning.
