The 6SL3520-0XM03-0AB0 is the PROFINET/EtherNet/IP variant of the SINAMICS G115D distributed drive at the 3 kW power level — the highest fanless rating in the G115D wall-mounted range. Delivering 15.4 A peak output in the FSB frame, it powers longer conveyor sections with real-time Ethernet communication and PROFIsafe network safety, all with natural convection cooling.

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

The three G115D electronic module variants share identical power hardware. 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. This is the preferred choice for SIMATIC-controlled conveyor lines. The AS-Interface variant (AF0) uses a two-wire AS-i bus with STO via F-DI. The I/O Control variant (AA0) uses terminal I/O with no fieldbus.

What makes the XM03 3 kW different from lower-power G115D variants?

The XM03 uses the FSB frame — 425 mm wide vs 380 mm for FSA — to accommodate the higher power electronics while retaining natural convection cooling with no fan. The frame measures 425 × 180 × 134 mm and weighs approximately 7.1 kg. The integrated braking circuit supports a minimum external resistance of 80 Ω (vs 200 Ω for FSA), reflecting the higher braking energy. The 24 V DC supply draws 290 mA for the PROFINET variant.

How does PROFIsafe work on the G115D?

On the PROFINET variant (AB0), Safe Torque Off (STO) can be activated via 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).

Frequently Asked Questions

Can this drive operate without a control cabinet?

Yes. The G115D is designed for cabinet-free, wall-mounted installation. IP65 protection eliminates the need for a separate enclosure. The FSB frame at 3 kW uses natural convection cooling — no fan, no maintenance.

Does the XM03 have a cooling fan?

No. The 3 kW XM03 uses natural convection cooling — the highest fanless rating in the G115D wall-mounted range. Only the 4 kW XM04 requires an integrated fan. This makes the XM03 a strong choice for noise-sensitive installations where 3 kW is sufficient.

Does the PROFINET variant also support EtherNet/IP?

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