The 6SL3520-0XN04-0AB0 combines 4 kW of conveyor drive power with PROFINET communication in the fan-cooled FSB frame. Rated at 10.2 A continuous (20.4 A overload) from a 380–480 V 3-phase supply, it integrates PROFINET IO, PROFIsafe (STO at SIL 3 / PL e), and EtherNet/IP over a single Ethernet cable — a cloud-ready distributed drive for pallet conveyors, merge units, and incline belts in automated distribution centers.

What does PROFINET bring to a 4 kW distributed drive?

The AB0 PROFINET interface eliminates the control cabinet PLC-to-drive wiring entirely — one Ethernet cable handles drive control, parameterization, safety, and diagnostics. Commissioning from TIA Portal uploads drive parameters from the project — no manual keypad entry per drive on a 50-drive conveyor line. PROFIsafe provides STO (Safe Torque Off) over the same cable, removing the separate safety relay and discrete wiring required on AS-Interface (AF0) and I/O Control (AA0) variants. For plants using Rockwell PLCs, the drive also speaks EtherNet/IP — one hardware SKU serves both Siemens and Allen-Bradley architectures. MindSphere connectivity enables cloud-based condition monitoring: track drive temperature, current draw, and runtime hours across a fleet of conveyor drives from a central dashboard.

Fan-cooled FSB: when passive cooling hits its limit

At 4 kW, natural convection can no longer dissipate the heat generated by the output stage. The fan-cooled FSB adds an integrated fan (and 35 mm of enclosure depth versus the fanless FSB) to maintain operation up to 55°C ambient. The fan is the only wear component — Siemens rates it for the drive's service life under normal conditions, but dusty or fibrous environments may require periodic cleaning. For conveyor segments below 3 kW where fanless operation is preferred, the fanless FSB (XH23/XM03, 425 × 180 × 134 mm) covers 1.1–3 kW.

XN04 vs. XM04 vs. XH24 — which catalog generation?

XN04, XM04, and XH24 all designate the same 4 kW FSB fan-cooled hardware — the difference is catalog generation, not drive capability. XM04 is the earliest designation, XN04 followed, and XH24 is the current catalog code. All three share identical mounting dimensions, power/current ratings, and communication interfaces. When replacing a drive, any of the three can substitute directly as long as the communication variant (AA0/AF0/AB0) matches.

Frequently Asked Questions

What is the 24 V DC current draw for this fan-cooled variant?

The fan-cooled FSB draws 510–550 mA from the 24 V DC control supply — roughly double the 250–290 mA of fanless FSB variants. When designing a multi-drive conveyor system, size the 24 V power supply to account for the fan current on all fan-cooled drives.

Can I use this drive for hoisting or vertical lifting applications?

The G115D is designed primarily for horizontal conveyor motion. For lifting or hoisting applications requiring a brake, consult the SINAMICS G120 series which provides dedicated hoist functionality including brake control and load monitoring.

Is an EMC filter included?

Yes. All G115D variants include an integrated RFI suppression filter meeting Category C2 (EN 61800-3) for industrial environments. No external filter is needed for compliance in industrial installations.
