The Siemens 6SL3520-1XA67-5AF0 is the most powerful SINAMICS G115D wall-mounted distributed drive, rated at 7.5 kW (10 hp) with 19 A rated output current for 380–480 V 3-phase supply in the FSC frame (425 × 180 × 169 mm). It combines the full AF0 feature set — PROFINET/EtherNet/IP communication, local remote operator panel, and daisy-chain power and communication connectors — with the highest power ceiling in the G115D wall-mounted family, delivering 550 Hz output from an IP65-rated enclosure purpose-built for large conveyor and material handling systems.

What does 7.5 kW drive on a conveyor line?

At 7.5 kW, the G115D powers the backbone conveyors: main trunk lines, pallet handling systems, incline/decline sections, and heavy-duty merges that move full totes or pallets. An airport baggage handling main collector conveyor or an e-commerce outbound sorter infeed line are typical applications. The 19 A output drives motors up to 10 hp — enough torque for loaded pallet conveyors, tyre and wheel handling lines in automotive assembly, and bulk material belt conveyors in food processing.

FSC frame — what changes from FSA and FSB?

The FSC frame (425 × 180 × 169 mm) is physically larger than FSB and adds an integrated external cooling fan — passive convection is insufficient at 5.5 kW and above. The fan is 24 V DC-powered and monitored; a blocked or failed fan triggers a warning via PROFINET diagnostics before thermal derating kicks in. Despite the fan, the enclosure maintains the full IP65/IP66 rating, making the FSC frame suitable for the same washdown and outdoor environments as the smaller fanless FSA and FSB variants.

Frequently Asked Questions

Is 7.5 kW the absolute ceiling for G115D wall-mounted?

Yes. 7.5 kW (19 A, FSC) is the highest power rating in the G115D wall-mounted catalog. For applications above 10 hp, Siemens offers the G120 and G120X series in higher power classes, or you can use multiple G115D drives with mechanical load sharing across conveyor zones.

What is the 24 V DC current draw on this FSC model?

The control electronics draw 580 mA at 24 V DC on the FSC frame — higher than FSA (~400 mA) and FSB (~510 mA) due to the integrated cooling fan. The drive generates its own 24 V from the 400 V AC mains input, so no external DC supply is needed.

Can the AF0 daisy-chain handle the full 7.5 kW load downstream?

Yes. The Q4/2 daisy-chain power connectors on the AF0 are rated for the full 400 V AC line current of all downstream drives combined. When daisy-chaining a 7.5 kW unit as the first in a line of smaller drives, size the supply cable to the first drive for the sum of all downstream loads — the Q4/2 connectors themselves are rated for 25 A continuous, sufficient for this unit plus downstream loads within the G115D family.
