The SINAMICS G115D 6SL3520-0XL00-5AF0 is a compact 0.55 kW wall-mounted distributed frequency converter for small conveyor motors in SIMATIC-based automation lines. It mounts at the motor to eliminate control cabinets and reduce wiring — ideal for short belt sections, roller beds, and material-handling transfer units.

What Are the Electrical Specifications?

The 6SL3520-0XL00-5AF0 delivers 0.55 kW continuous output at 3.4 A from a 380–480 V 3-phase supply. This is the entry-level power rating in the G115D FSA frame, suited for the lightest conveyor sections. Overload capability of 150% for 57 seconds and 200% for 3 seconds handles belt startup. Compatible with SIMOGEAR 2KJ8 geared motors up to frame size 132 in IE3 and IE4 efficiency classes.

Where Is It Installed?

IP65/IP66 and UL Type 4X permit direct installation on the machine or wall in wet, dusty, and washdown production areas — no enclosure required. The FSA housing measures 380 × 216 × 129 mm across all power ratings. Full-load ambient range is −30°C to +40°C, derated to +55°C. Natural convection cooling eliminates fan-related service.

How Does It Connect to the Control System?

Fieldbus connectivity uses PROFINET and EtherNet/IP via an M12 port. PROFIsafe provides SIL 3 STO over the same fieldbus. Preconfigured TIA Portal function blocks simplify SIMATIC S7 commissioning. Wireless setup via web server and SD card parameter backup enable rapid device replacement without re-engineering.

Frequently Asked Questions

Is the 0.55 kW variant sufficient for my conveyor application?

The 0.55 kW G115D suits conveyor motors rated up to 0.55 kW — typically short belt sections, small roller conveyors, and light transfer units. Verify your motor nameplate power and starting torque requirements. If the motor is rated above 0.55 kW, step up to the 0.75 kW or 1.1 kW variant within the same FSA frame.

Can the G115D be programmed without TIA Portal?

Basic parameterization is possible via the optional local control panel or the integrated web server without TIA Portal. However, full PROFINET integration, PROFIsafe configuration, and function block utilization require TIA Portal engineering software.

What protection does the drive have against short circuits?

The G115D includes output short-circuit and ground-fault protection monitored by the power module. Upon detection, the drive immediately disables the output stage and reports the fault via fieldbus. The drive must be power-cycled and the fault cleared before resuming operation.
