The 6SL3520-0XN05-5AB0 is the 5.5 kW PROFINET G115D in the FSC frame — the middle of the fan-cooled power range, sitting between the 4 kW FSB and the 7.5 kW FSC ceiling. Rated at 13.2 A continuous (26.4 A overload) from 380–480 V 3-phase, it combines PROFINET IO, PROFIsafe, and EtherNet/IP for heavy conveyor duty in automated logistics and parcel handling centers.

Why 5.5 kW with PROFINET — what applications drive this combination?

The 5.5 kW FSC is the workhorse for medium-to-heavy conveyor applications where Ethernet integration adds operational value beyond basic motor control. Typical deployments include pallet conveyors in automated warehouses, airport baggage handling merges and diverters, and cross-belt sorters where coordinated multi-drive motion requires precise speed synchronization over the network. PROFINET enables isochronous real-time communication for multi-axis coordination, while PROFIsafe delivers STO (SIL 3 / PL e) without the discrete safety wiring burden that scales with drive count. For a sorter with 20 drives, PROFIsafe over Ethernet eliminates 40 wires (two per STO channel) versus discrete F-DI wiring.

FSC frame: same footprint as 4 kW FSB, more power

The FSC enclosure (425 × 180 × 169 mm, 7.85 kg) shares the identical footprint and mounting pattern as the 4 kW fan-cooled FSB — the difference is inside. Higher-rated IGBTs and a more capable DC link support 13.2 A continuous output at 5.5 kW (vs 10.2 A at 4 kW in FSB). This means a conveyor system designer can standardize on one enclosure size across a 4–7.5 kW power range, simplifying mechanical mounting and spare parts. The integrated fan is the same across both frames — Siemens rates it for the drive's full service life under normal ambient conditions.

Fit in the G115D power range: FSC 5.5 kW in context

The G115D spans 0.37–7.5 kW across three frame sizes. The 5.5 kW FSC occupies the second-highest power tier, below only the 7.5 kW FSC (XH27/XN07). When specifying: choose 5.5 kW when the conveyor segment peaks at ~13 A under overload — typical for pallet conveyor runs of 20–30 m or incline belts with 500+ kg product loads. For runs exceeding 15 A continuous, step up to the 7.5 kW FSC (XN07/XH27, 19 A rated / 38 A overload).

Frequently Asked Questions

Does the PROFINET variant support daisy-chain Ethernet topology?

Yes. The G115D AB0 variant includes an integrated 2-port PROFINET switch, enabling line topology — each drive connects to the next in a daisy chain, reducing Ethernet switch port count and cabling in long conveyor lines. Media redundancy (MRP) is supported for ring topologies.

Can I replace an XN05 with an XH25?

Yes — XN05 (this product) and XH25 are the same 5.5 kW FSC hardware with different catalog generation codes. Both share identical electrical ratings, dimensions, and communication interfaces. XH25 is the current catalog designation.

What motor types can this drive control?

The G115D controls IE3 3-phase asynchronous motors and IE4 synchronous reluctance motors. It is preconfigured for SIMOGEAR 2KJ8 geared motor combinations. Third-party motors within the voltage/current rating are also supported.
