The SINAMICS G115D 6SL3520-0XL00-7AF0 is a 0.75 kW wall-mounted distributed frequency converter for light-duty horizontal conveyor drives in SIMATIC automation environments. Mounting directly at the conveyor motor eliminates control cabinet space and reduces cabling cost compared to centralized drive panels.

What Motor Power and Overload Does It Support?

The 6SL3520-0XL00-7AF0 provides 0.75 kW continuous output at 4.4 A from a 380–480 V 3-phase supply, sized for lighter conveyor sections, small roller beds, and material-handling transfer points. Overload rating reaches 150% for 57 seconds and 200% for 3 seconds. It drives SIMOGEAR 2KJ8 geared motors up to frame size 132 across IE3 asynchronous and IE4 synchronous reluctance types.

What Are the Installation and Environmental Ratings?

IP65/IP66 and UL Type 4X protection allows installation directly in wet, dusty, or washdown production zones without an enclosure. The FSA frame measures 380 × 216 × 129 mm and wall-mounts on the machine frame. Full-load ambient range is −30°C to +40°C, extendable to +55°C with output derating. An integrated C2 EMC filter ensures compliance with IEC 61800-3 for industrial networks.

How Does It Integrate with Controls?

The drive communicates via PROFINET and EtherNet/IP through an M12 interface, with PROFIsafe for safety-rated STO. TIA Portal function blocks simplify commissioning with SIMATIC S7, while the web server and SD card slot support wireless setup and rapid device replacement without re-commissioning.

Frequently Asked Questions

How do I choose between 0.75 kW and 1.1 kW G115D variants?

Match the drive power rating to your conveyor motor's nameplate power. The 0.75 kW variant (4.4 A) suits motors up to 0.75 kW — typical for light roller beds and transfer conveyors. The 1.1 kW variant (6.2 A) covers heavier sections. Both share the FSA frame, so mechanical fit is identical.

Does the G115D support energy-saving operation?

Yes — the G115D includes V/f ECO mode for variable-torque loads and encoderless vector control for optimized motor efficiency across the speed range. The energy-saving control mode automatically reduces flux current under light load conditions.

What is the maximum motor cable length?

For FSA frame drives at the factory 4 kHz pulse frequency, shielded motor cables up to 15 m are supported. Longer runs require an output reactor or sine-wave filter to mitigate reflected-wave voltage stress on the motor windings.
