The 6SL3520-1XM00-3AB0 is the 0.37 kW G115D in the FSA frame with the AB-suffix configuration. Electrically identical to the 3AF0 at 1.3 A continuous and 2.6 A peak, it drives small conveyor rollers, belt sections, and auxiliary material-handling equipment where the lowest G115D power rating is sufficient. The AB variant provides enhanced communication capabilities with a specific I/O and communication mix tailored for distributed automation networks — a configuration option alongside the 3AF0's PROFINET emphasis and the 3AA0's base functionality.

The FSA enclosure measures 380 × 216 × 129 mm — the most compact in the G115D range — and mounts directly on the machine frame. IP65 (connectors) / IP66 (cable glands) and UL Type 4X indoor protection suit washdown and dusty production environments. Standard across all G115D: integrated C2 EMC filter, internal braking resistor, STO SIL 2 via Profisafe, SAM web-server commissioning, and support for IE2/IE3/IE4 motors with V/f or vector control from 0–550 Hz.
