The SINAMICS G115D 6SL3520-0XL01-1AF0 is a 1.1 kW wall-mounted distributed frequency converter for horizontal conveyor applications in SIMATIC-based automation systems. It mounts directly at the conveyor motor, eliminating the need for a control cabinet and reducing installation footprint.

What Motor Power and Overload Capability Does It Offer?

The 6SL3520-0XL01-1AF0 delivers 1.1 kW continuous output at 6.2 A from a 380–480 V 3-phase supply, making it suitable for mid-range conveyor sections. Overload capability reaches 150% of rated current for up to 57 seconds and 200% for 3 seconds, covering conveyor startup and peak torque demands. 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?

Rated IP65/IP66 and UL Type 4X, the G115D operates in wet, dusty, and washdown environments without a protective enclosure. The FSA frame measures 380 × 216 × 129 mm and mounts directly on the machine frame or wall. Operating temperature spans −30°C to +40°C at full rated load, with derated operation up to +55°C. Natural convection cooling eliminates fan-related maintenance.

How Does It Integrate with the Control System?

The drive communicates via PROFINET and EtherNet/IP through an M12 interface, supporting PROFIsafe for STO (Safe Torque Off) over the same network. Preconfigured function blocks in TIA Portal simplify commissioning with SIMATIC S7 controllers. A web server module enables wireless commissioning, and an SD card slot supports parameter backup and rapid device replacement.

Frequently Asked Questions

How do I choose between the 1.1 kW and 1.5 kW G115D variants?

The choice depends on your conveyor motor's power rating. The 1.1 kW variant (6.2 A) suits motors up to 1.1 kW, while the 1.5 kW variant (8.2 A) handles heavier conveyor sections. Both share the same FSA frame dimensions, so mechanical fit is identical — select by motor power and peak torque requirements.

Does the G115D require a separate 24 V DC power supply?

The G115D can be ordered with an integrated 24 V DC power supply option for the control electronics. Without this option, an external 24 V DC supply is required. Check the specific variant suffix for the power supply configuration.

What motor cable length is supported?

The G115D FSA frame supports shielded motor cables up to 15 m at the factory-default 4 kHz pulse frequency. Longer cable runs may require an output reactor or sine-wave filter to manage reflected wave effects.
