The SINAMICS G115D 6SL3520-0XL01-1AB0 is a 1.1 kW distributed frequency converter that mounts at the conveyor motor, removing the need for a dedicated drive cabinet. Designed for SIMATIC-controlled production lines, it reduces wiring runs and panel space compared to centralized VFD architectures.

What Are the Electrical Ratings?

The 6SL3520-0XL01-1AB0 delivers 1.1 kW continuous output at 6.2 A from a 380–480 V 3-phase mains supply. Overload performance reaches 150% for 57 seconds and 200% for 3 seconds, covering the torque peaks typical of conveyor belt startup. Compatible motors include SIMOGEAR 2KJ8 geared units up to frame size 132 in IE3 asynchronous and IE4 synchronous reluctance designs.

What Installation Conditions Does It Require?

IP65/IP66 and UL Type 4X ratings permit installation directly in production areas subject to water spray, dust, and washdown procedures — no protective cabinet required. The FSA frame occupies 380 × 216 × 129 mm and mounts on the machine frame or wall. Full-load operation is rated from −30°C to +40°C, with derated capability to +55°C. Natural convection cooling eliminates fans and associated maintenance.

How Does It Connect to the Automation System?

The drive uses PROFINET and EtherNet/IP via M12 for fieldbus communication, with PROFIsafe providing SIL 3 STO over the same network. TIA Portal integration includes preconfigured function blocks for SIMATIC S7 controllers. Onboard features include a web server for wireless commissioning and an SD card slot for parameter cloning during device swap-out.

Frequently Asked Questions

How does the G115D handle communication loss with the controller?

The drive can be configured with a fail-safe response to PROFINET or EtherNet/IP communication loss — typically triggering a controlled stop or STO activation. The specific behavior is parameterized in TIA Portal during commissioning and can be tailored to the application's safety requirements.

What is the expected service life of a G115D drive?

The G115D is designed for a typical service life exceeding 10 years under rated conditions. Key lifetime factors are ambient temperature, load cycling frequency, and motor cable length. Operating within the rated temperature range (−30°C to +40°C) and keeping motor cable runs within 15 m maximizes longevity.

Can this drive replace a SINAMICS G110D on an existing conveyor?

Yes — the G115D is the direct successor to the G110D and shares the same FSA mounting footprint and motor compatibility. Electrical interfaces are largely pin-compatible, though TIA Portal hardware configuration must be updated to the G115D device description file. Verify connector and communication variant compatibility before ordering.
