At 0.75 kW (2.2 A rated, 4.4 A overload), the 6SL3520-1XE40-7AB0 proves that the smallest drive on the conveyor line runs the same software stack as the largest. PROFINET telegrams, TIA Portal function blocks, and diagnostic LED patterns are identical from 0.75 kW FSA to 7.5 kW FSC — the commissioning engineer uses the same workflow regardless of power rating.

Why does software commonality matter at the low-power end?

On a conveyor project with 300 drives — 250 of them at 0.75 kW — the engineering hours are dominated by the low-power units simply because there are so many of them. The G115D's macro-based commissioning loads motor data, ramp times, braking parameters, and PROFINET mapping from a single selection in TIA Portal. An engineer commissions a 0.75 kW FSA the same way as a 7.5 kW FSC — same macro, same telegram, same diagnostic interface. The integrated C2 filter (standard on 1XE) means the EMC compliance documentation is identical per drive — no variation in filter configuration across power ratings. With 43.1 W power loss and natural convection cooling, the 0.75 kW FSA is the quietest, most maintenance-free drive on the line.

Key specifications

The drive operates from a 3 AC 380–480 V supply (45–66 Hz) with an output frequency range of 0–550 Hz. High-overload capability delivers 200% for 3 seconds and 150% for 57 seconds. The 350 Ω integrated braking resistor (10 W continuous) supports dynamic braking. Integrated PROFINET and Ethernet IP interfaces connect directly to SIMATIC controllers. The built-in C2 RFI filter meets EN 61800-3 Category C2 conducted emission limits for industrial environments.
