The 6SL3520-0XN00-3AB0 is the PROFINET/EtherNet/IP variant of the SINAMICS G115D distributed drive platform — the entry-level 0.37 kW model in the FSA frame. With 2.6 A peak output, it powers the lightest conveyor sections with real-time Ethernet communication and integrated PROFIsafe for network safety.

What makes the PROFINET variant different from AS-Interface and I/O Control?

The three G115D electronic module variants share identical power hardware — the difference is in communication and safety architecture. The PROFINET variant (AB0 suffix) provides dual-protocol PROFINET and EtherNet/IP connectivity with full real-time capability, including PROFIsafe for functional safety over the network. The AS-Interface variant (AF0) uses a simple two-wire AS-i bus with STO via hardwired F-DI. The I/O Control variant (AA0) uses terminal I/O with no fieldbus — for standalone or non-networked applications.

What motors can the G115D XN00 drive at 0.37 kW?

The drive is preconfigured for SIMOGEAR 2KJ8 geared motors in frame sizes 71–132, available in IE3 asynchronous or IE4 synchronous reluctance variants. At 0.37 kW, the drive typically pairs with smaller geared motors for light-duty accumulation conveyors, diverter sections, or packaging line infeed/outfeed rollers. The integrated brake control supports 180 V DC electromechanical brakes up to 0.8 A or direct 380–480 V AC brake coils.

How does PROFIsafe work on the G115D?

On the PROFINET variant (AB0), Safe Torque Off (STO) can be activated either via the fail-safe digital inputs (F-DI) or through PROFIsafe over the PROFINET network — eliminating dedicated safety wiring. The drive achieves SIL 2 (IEC 61508) and PL d Cat 3 (EN ISO 13849-1). PROFIsafe is not available on AS-Interface (AF0) or I/O Control (AA0) variants.

Frequently Asked Questions

Can this drive operate without a control cabinet?

Yes. The G115D is designed for cabinet-free, wall-mounted installation directly on the machine frame. IP65 protection (plug-in connectors) or IP66 (cable gland entry) eliminates the need for a separate enclosure. The FSA frame measures 380 × 216 × 129 mm and uses natural convection cooling — no fan, no maintenance.

Is 0.37 kW sufficient for my conveyor application?

0.37 kW (0.5 hp) is suitable for light-duty conveyor sections — accumulation zones, small roller beds, belt conveyors under 1 m width at moderate speed, or diverter arms. For continuous heavy-load conveying, consider stepping up to the 0.55 kW or 0.75 kW XN00 variants. All share the same FSA frame and mounting dimensions, making upgrades mechanically straightforward.

Does the PROFINET variant also support EtherNet/IP?

Yes. The PROFINET variant (AB0) is dual-protocol capable — supporting both PROFINET and EtherNet/IP on the same hardware for mixed-vendor automation environments.
