The 6SL3520-0XM00-7AF0 is the PROFIsafe-equipped variant of the SINAMICS G115D distributed drive, delivering 0.75 kW from a fanless FSA frame for horizontal conveyor applications. With its integrated C2 EMC line filter and wall-mounted IP65/IP66 enclosure, it replaces control-cabinet VFDs with a machine-mounted solution that handles safety signaling natively over PROFINET.

When should I choose the PROFIsafe variant over the standard G115D?

Choose the AF0 suffix when your conveyor application requires functional safety up to SIL 2 (IEC 61508) or PL d Cat 3 (EN ISO 13849-1) without external safety relays. The AF0 variant carries safety-rated STO (Safe Torque Off) commands over the same PROFINET cable — no separate hardwired safety circuit needed. If your application only needs standard STO via a fail-safe digital input, the AB0 or AA0 variants are sufficient. The C2 EMC filter (EN 61800-3) is integrated across both AF0 and AB0 variants, making them suitable for industrial environments without additional external filtering.

How does daisy-chain power distribution simplify multi-drive conveyor installations?

The G115D wall-mounted converter supports daisy-chain power distribution through Q4/2 connectors for the 400 V AC line supply and M12 L-coding connectors for the 24 V DC control supply. Up to 12 A+12 A at 40°C can pass through the 24 V daisy chain (IEC 2.5 mm² cabling). This means a single power drop can feed multiple drives along a conveyor line — no individual circuit protection per drive, no star-wired control cabinet. The M12 I/O and communication connectors also support loop-through, so PROFINET cabling follows the same daisy-chain topology as the power wiring.

Frequently Asked Questions

Does the G115D FSA frame include a cooling fan?

No. The FSA frame (0.37 to 1.5 kW) is cooled by natural convection — it is completely fanless. This eliminates fan maintenance, reduces audible noise, and improves reliability in dusty or washdown environments. The FSB and FSC frames include a cooling fan.

What motors is the G115D compatible with?

The G115D is pre-engineered for SIMOGEAR 2KJ8 geared motors (frame sizes 71 to 132, IE2/IE3/IE4) but also works with standard Siemens asynchronous, synchronous reluctance, and permanent-magnet synchronous motors. Motor cable length is limited to 15 m shielded — plan drive placement accordingly.
