The 6SL3520-1XH60-5AA0 is the 0.55 kW variant of the G115D FSA distributed drive, delivering 3.4 A with standard hardwired I/O. At roughly 50% more power than the 0.37 kW entry point, it handles conveyor sections where the motor faces slightly higher friction, longer belt length, or heavier product weight — still within the FSA fanless envelope.

0.37 kW vs 0.55 kW — what changes?

Both share the FSA frame, the 380 mm housing width, the fanless convection cooling, and the same mechanical mounting dimensions. The difference is purely in the power stage: the 0.55 kW unit delivers 3.4 A versus 2.6 A, enough to drive a motor with roughly 50% more shaft power. In practice, this means a conveyor OEM can standardize on the G115D platform and swap the drive size based on the motor nameplate — same mounting holes, same wiring, same commissioning workflow. For the end user, a 0.55 kW belt section pulling a heavier product or running at higher speed does not trip on overcurrent where a 0.37 kW drive would be at its limit.

FSA hardwired I/O — the simplest G115D configuration

The AA0 hardwired-I/O variant keeps the interface minimal: digital inputs for run/stop and fault reset, an analog input for speed reference. No fieldbus configuration, no network addressing, no additional engineering tool beyond setting the DIP switches to match the analog signal type. For conveyor module builders who ship standardized belt sections with pre-wired drives, this is the configuration that installs fastest and requires the least on-site commissioning.
