The SINAMICS G115D 6SL3520-2XA61-5AA0 is a 1.5 kW wall-mounted distributed drive with a basic I/O control interface — no fieldbus communication. Rated at 4.1 A HO with 8.2 A peak (200% for 3 s), it operates from 380–480 V 3 AC in the FSA frame (380 × 156 × 129 mm) with natural convection cooling. An integrated Category C2 EMC filter and braking chopper are standard. IP65/IP66 rated for direct machine mounting.

How does the AA0 I/O configuration differ from fieldbus variants?

The AA0 suffix provides a basic digital I/O interface without PROFINET or EtherNet/IP. Control is via hardwired digital inputs including one fail-safe digital input (F-DI) for STO (Safe Torque Off). This variant suits applications where a dedicated fieldbus network is not required — the drive is controlled by discrete I/O signals from a PLC or controller. For PROFINET/EtherNet/IP communication with PROFIsafe, see the AF0 variant (e.g. 6SL3520-2XA61-5AF0). All variants share the same power stage, frame dimensions, and motor compatibility with SIMOGEAR 2KJ8 geared motors.
