The 6SL3520-0XA60-7AA0 delivers 0.75 kW (2.2 A rated, 4.4 A overload) in the FSA frame — the highest power available without stepping up to the larger FSB platform. For conveyor OEMs, this means one compact drive size covers motors from 0.37 to 0.75 kW with a single mounting footprint and commissioning workflow.

When should you step up from FSA to FSB?

The FSA frame handles up to 0.75 kW with natural convection alone. The next step — 1.1 kW — stays in FSA, but 2.2 kW crosses into FSB territory where the larger heatsink area is needed. If your conveyor line mixes 0.75 kW and 2.2 kW zones, you will have two frame sizes on the line — but the TIA Portal project, function blocks, and spare-parts strategy remain identical across both.

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. Integrated PROFINET and Ethernet IP interfaces connect directly to SIMATIC controllers. The built-in RFI filter meets Category C2 requirements.
