The 6SL3520-0XH60-3AF0 is the AS-Interface variant of the SINAMICS G115D distributed drive platform — the 0.37 kW entry point in the FSA frame. With 2.6 A peak output, it powers light conveyor sections where simple AS-i bus wiring and decentralized control reduce installation cost.

How does the AS-Interface variant differ from PROFINET and I/O Control?

The three G115D electronic module variants share identical power hardware — the difference is in communication and I/O architecture. AS-Interface (AF0 suffix) connects the drive over the AS-i two-wire bus, carrying power and data on a single unshielded cable — ideal for conveyor installations with many distributed drives. The PROFINET variant (AB0) adds Ethernet-based real-time communication and PROFIsafe. The I/O Control variant (AA0) uses hardwired terminal I/O with no fieldbus — for standalone or non-networked applications.

What motors can the G115D XH60 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, it 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.

What safety functions are integrated?

All G115D variants include Safe Torque Off (STO) at SIL 2 (IEC 61508) and PL d Cat 3 (EN ISO 13849-1). On the AS-Interface variant, STO is activated via the fail-safe digital inputs (F-DI) — the drive's two configurable digital inputs can be assigned as F-DI channels. PROFIsafe is only available on the PROFINET variant (AB0).

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.

Does the AS-Interface variant support EtherNet/IP?

No. The AS-Interface variant (AF0) communicates exclusively over the AS-i bus. For EtherNet/IP connectivity, select the PROFINET variant (AB0), dual-protocol capable for both PROFINET and EtherNet/IP.

What is the difference between XH60 and XN00 frame codes?

Both XH60 and XN00 use the same FSA physical frame (380 × 216 × 129 mm) with natural convection cooling. The XH60 designation appears on an earlier product variant, while XN00 is the current production designation. Physical dimensions, mounting, and thermal characteristics are identical between the two codes.
