The SINAMICS G115D 6SL3520-0XL00-5AA0 is the 0.55 kW entry-level wall-mounted distributed frequency converter for light-duty conveyor motors in SIMATIC-based automation systems. By mounting at the motor, it removes the drive cabinet requirement and minimizes installation cost for short belts, small roller conveyors, and material-handling transfer points.

What Are the Electrical Specifications?

The 6SL3520-0XL00-5AA0 provides 0.55 kW continuous at 3.4 A from a 380–480 V 3-phase supply — the smallest power rating in the G115D FSA frame. Overload rating reaches 150% for 57 seconds and 200% for 3 seconds, covering light conveyor startup torque transients. The drive is compatible with SIMOGEAR 2KJ8 geared motors up to frame size 132, supporting IE3 asynchronous and IE4 synchronous reluctance motor types.

Where Can It Be Installed?

IP65/IP66 and UL Type 4X ratings permit installation directly in wet, dusty, and washdown production areas without a protective enclosure. The FSA housing is 380 × 216 × 129 mm across all G115D power ratings. Full-load ambient temperature range is −30°C to +40°C, extendable to +55°C with output derating. Natural convection cooling means no fans to service or replace.

How Does It Communicate with the Automation System?

The drive connects via PROFINET and EtherNet/IP through an M12 interface, with PROFIsafe for SIL 3 STO over the same fieldbus. Preconfigured TIA Portal function blocks accelerate SIMATIC S7 commissioning. The integrated web server supports wireless setup, and SD card parameter backup enables rapid device replacement without re-engineering the automation program.

Frequently Asked Questions

What is the total cost advantage of a distributed drive vs. a cabinet VFD?

A distributed G115D installation eliminates the control cabinet, cabinet cooling fan, main disconnect switch, and long shielded motor cable — typically saving 30–50% in total installed cost for conveyor applications compared to an equivalent cabinet-mount VFD. Additional savings come from reduced engineering time and smaller electrical room footprint.

Can this drive be used in a safety-rated application?

Yes — the G115D supports STO (Safe Torque Off) via PROFIsafe (SIL 3 / PL e) or via a fail-safe digital input (F-DI). The safety function is integrated into the drive firmware and does not require an external safety relay, simplifying the safety circuit design.

Is the G115D suitable for outdoor installation?

With IP65/IP66 and UL Type 4X ratings, the G115D can be installed outdoors when protected from direct sunlight and extreme weather. The −30°C to +40°C ambient range covers most outdoor industrial environments. For outdoor installations, Siemens recommends an additional sun shield and verification that condensation cycling does not exceed the enclosure's design limits.
