The 6SL3520-1XK05-5AF0 provides 5.5 kW at 13.2 A in the FSC frame — the stepping stone between the compact FSA and the 7.5 kW top-of-range. The AF-suffix variant adds enhanced communication capabilities for integration into SIMATIC-controlled distributed automation networks, with commissioning via the SAM web server or TIA Portal Startdrive. At 26.4 A peak (200% for 3 seconds), the drive covers conveyor sections, transfers, and processing stations where 0.37–4.0 kW FSA/FSB drives are undersized.

The IP65/IP66 FSC enclosure mounts at the point of use, eliminating control cabinet cost and footprint in distributed architectures. An integrated C2 EMC filter, internal braking resistor, and STO SIL 2 via Profisafe are standard. The 425 × 240 × 169 mm housing operates from -30°C to 40°C and supports IE2/IE3 asynchronous and IE4 synchronous reluctance motors with V/f or vector control across a 0–550 Hz output range.
