The 6SL3520-0XN05-5AF0 brings 5.5 kW of conveyor drive power with AS-Interface communication in the FSC frame. Rated at 13.2 A continuous (26.4 A overload) from a 380–480 V 3-phase supply, it handles the heaviest conveyor segments in logistics automation — pallet handling systems, merge and sortation units, and long incline belts moving bulk product flows in distribution centers and airport baggage systems.

What distinguishes the 5.5 kW FSC from the 4 kW FSB?

The FSC frame (425 × 180 × 169 mm, 7.85 kg) shares the same enclosure dimensions as the fan-cooled FSB, but houses a higher-rated IGBT power stage — 13.2 A continuous versus 10.2 A on the 4 kW FSB. The 330 g weight difference (7.85 vs 7.52 kg) reflects the heavier power semiconductors and heat sink. Both are fan-cooled IP65 wall-mounted drives. The FSC frame serves 5.5–7.5 kW; below that, the FSB fan-cooled covers 4 kW and the fanless FSB covers 1.1–3 kW.

AS-Interface at 5.5 kW — when the two-wire bus still makes sense

At first glance, running a 5.5 kW drive over a two-wire AS-i bus seems counterintuitive — but AS-Interface carries only control signals and diagnostics, not motor power. The 380–480 V 3-phase supply and the AS-i bus cable are separate circuits. For plants already standardized on AS-Interface with an installed AS-i master and cable infrastructure, adding a 5.5 kW G115D drive means connecting the yellow AS-i cable and the 3-phase power — no new fieldbus gateway, no Ethernet switch port. The drive receives speed setpoints, start/stop commands, and direction signals over AS-i, while returning current draw, temperature, and fault status to the PLC.

How does XN05 relate to XH25 — same drive, different catalog era?

XN05 and XH25 are the same 5.5 kW FSC hardware under different catalog designations. XN05 is the intermediate-generation code; XH25 is the current catalog designation. Mounting dimensions, power ratings, and communication interfaces are identical. When ordering a replacement, XH25 is the current-catalog equivalent — but XN05 stock remains fully functional and interchangeable.

Frequently Asked Questions

What safety function is available on the AS-Interface variant?

STO (Safe Torque Off) is implemented via a fail-safe digital input (F-DI). Unlike the PROFINET AB0 variant which provides PROFIsafe over Ethernet, the AF0 AS-Interface variant requires discrete safety wiring to the F-DI terminal in addition to the AS-i bus cable.

What is the 24 V DC current draw?

The FSC frame draws approximately 510–550 mA from the 24 V DC control supply for logic, communication, and the integrated cooling fan. This is comparable to the fan-cooled FSB.

Can this drive run a 5.5 kW IE4 synchronous reluctance motor?

Yes. The G115D supports IE3 asynchronous and IE4 synchronous reluctance motors. For SIMOGEAR combinations, select the corresponding 2KJ8 motor variant.
