The 6SL3520-1XC00-3AA0 is the simplest SINAMICS G115D variant — 0.37 kW in FSA frame (380 × 156 × 129 mm) with C-connector and AA0 I/O Control. Rated for 1.3 A continuous output (HO) at 380–480 V three-phase, it provides basic speed control via digital and analog inputs without any fieldbus configuration. The IP65 enclosure mounts directly on the conveyor frame, eliminating control cabinet space and motor cable runs.

When does hardwired I/O make sense vs PROFINET?

AA0 I/O Control suits fixed-speed or simple analog speed-reference applications where a PLC sends run/stop and speed commands over hardwired signals. No network configuration, no GSDML file, no IP address assignment — wire the terminals and the drive runs. For multi-axis coordinated conveyors with safety integration, the AF0 PROFINET variant (1XC00-3AF0) provides daisy-chain networking and PROFIsafe that hardwired I/O cannot. Choose AA0 when the control architecture is already wired and fieldbus adds complexity without benefit.
