The 6SL3520-1XL01-1AA0 is the 1.1 kW G115D FSA drive in the AA-suffix base configuration — the leanest 1.1 kW variant for decentralized applications where the machine controller handles sensor logic and safety coordination upstream. Electrically identical to the 1AB0 and 1AF0 at 3.1 A continuous (6.2 A peak), it delivers the same motor control without the additional I/O or network interface hardware. The 1XL FSA enclosure (380 × 216 × 129 mm) provides IP65/IP66 protection for machine-mounted installation.

The AA base variant covers essential drive functions: digital inputs for run/stop and direction, one STO channel, and the integrated C2 EMC filter. When the application does not need the expanded I/O of the AB variant or the PROFINET interface of the AF variant, the AA configuration avoids hardware overhead while preserving full G115D motor control — 200% overload for 3 seconds, internal braking chopper, and SAM web-server commissioning. For machines where every I/O point is already accounted for in the PLC architecture, the AA variant is the right fit.
