The 6SL3520-1XM03-0AA0 is the 3 kW G115D FSB drive in the AA-suffix base configuration — the essential fanless 3 kW variant for decentralized applications where the machine controller handles sensor logic and safety coordination upstream. Electrically identical to the 0AB0 at 7.7 A continuous (15.4 A peak), it delivers the same motor control without the additional I/O hardware. The 1XM FSB enclosure (425 × 240 × 134 mm) cools entirely by natural convection — no fan to maintain, no fan noise, and unrestricted mounting orientation.

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. The fanless FSB design at 3 kW is the ceiling for passive cooling in the G115D lineup — every power class above this requires an integrated fan. Standard features: 200% overload for 3 s, internal braking chopper, STO SIL 2, SAM web-server commissioning, IP65/IP66 protection.
