The 6SL3520-0XN00-7AF0 is the AS-Interface variant of the SINAMICS G115D distributed drive platform in FSA frame. Rated at 0.75 kW with 4.4 A peak output, it powers mid-range horizontal conveyor sections where simple AS-i bus wiring reduces installation cost across distributed nodes.

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

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 both power and data on a single unshielded cable. This suits conveyor installations with many distributed drives where minimizing wiring is the priority. The PROFINET variant (AB0) adds Ethernet-based real-time communication and PROFIsafe for safety over the network. The I/O Control variant (AA0) uses hardwired terminal I/O with no fieldbus — preferred for standalone operation or non-networked control panels.

What motors can the G115D XN00 drive?

The drive is preconfigured for SIMOGEAR 2KJ8 geared motors in frame sizes 71–132, available in IE3 asynchronous or IE4 synchronous reluctance variants. Motor speed ranges from 300–1500 rpm or 300–3000 rpm depending on the motor selection. The integrated brake control supports 180 V DC electromechanical brakes up to 0.8 A or direct 380–480 V AC brake coils up to 1 A.

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), requiring the PROFINET communication layer.

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), which supports both PROFINET and EtherNet/IP as dual-protocol capable.

What does the XN00 frame code indicate?

XN00 designates the FSA frame size covering 0.37–0.75 kW ratings with natural convection cooling. The frame hardware measures 380 × 216 × 129 mm — identical in physical dimensions to XN01 (1.1 kW). The designation reflects the power class, not a physical difference.
