The 6SL3520-1XL01-5AA0 delivers 1.5 kW in the G115D FSA frame with the AA-suffix base I/O configuration — the essential decentralized drive for cost-sensitive applications where the full enhanced I/O set is not required. Electrically identical to the 5AB0 at 4.1 A continuous and 8.2 A peak, it provides the same motor control performance in a leaner I/O package. The 1XL FSA enclosure (380 × 216 × 129 mm) mounts directly on the machine frame with IP65/IP66 protection.

The AA base configuration covers the core decentralized drive needs: digital I/O for start/stop and direction control, one safe torque off (STO) channel, and the integrated C2 EMC filter. For applications needing additional I/O channels or expanded safety interfaces, the AB enhanced variant adds those — but when the machine's control architecture already handles sensor feedback and safety logic upstream, the AA variant avoids paying for unused I/O. Standard G115D features apply: 200% overload for 3 s, internal braking chopper, STO SIL 2, and SAM web-server commissioning.
