The 6SL3520-0XK00-7AF0 is a 0.75 kW SINAMICS G115D distributed wall-mounted frequency converter with the AF0 I/O interface, housed in the compact FSA frame. Delivering 4.4 A of output current, this drive mounts directly on the machine frame alongside a SIMOGEAR geared motor for light to medium-duty horizontal conveyor sections. It operates from a 3AC 380-480 V supply with an output frequency range of 0-550 Hz and full TIA Portal integration for commissioning, parameterization, and diagnostics.

When does the 0.75 kW rating fit your conveyor application?

The 0.75 kW FSA variant bridges the gap between the entry-level 0.55 kW models and the mid-range 1.1 kW models in the G115D lineup. It is sized for conveyor sections handling moderate product weights — individual items or accumulated loads up to approximately 100 kg at standard material handling speeds. If your conveyor section currently uses a 0.75 kW centralized drive, the G115D 0.75 kW variant provides a direct power-equivalent replacement with the added benefits of distributed mounting, eliminating the control cabinet footprint and long motor cable runs.

How does distributed mounting simplify conveyor automation?

Traditional conveyor drives require a centralized control cabinet housing the VFD, with shielded motor cables running from the cabinet to each motor across the conveyor line. The G115D flips this model: the converter mounts directly on the machine frame near the motor, connected via short cable runs. This distributed architecture reduces cable cost, eliminates voltage-reflection stress on motor windings from long cable runs, and frees up cabinet real estate for other automation equipment. With IP65 protection and an operating temperature range of -30 °C to +40 °C, the drive handles washdown areas and unheated logistics environments without additional enclosures.

What safety and control features are integrated?

The G115D includes Safe Torque Off (STO) as standard, configurable via a fail-safe digital input (F-DI) or over PROFINET using PROFIsafe. This allows the drive to participate in a machine-wide safety concept without external safety relays for the stop function. On the control side, the converter supports V/f, V/f ECO, and sensorless vector control, with automatic motor adaptation when paired with a SIMOGEAR geared motor. Communication runs over PROFINET or EtherNet/IP via an M12 connector, with full integration into TIA Portal for commissioning, parameterization, and diagnostics.

Frequently Asked Questions

Can I use this drive with a motor other than SIMOGEAR?

The G115D is mechanically and electrically optimized for SIMOGEAR 2KJ8 geared motors with IE3 asynchronous or IE4 synchronous reluctance motors. While it can drive any compatible 3-phase induction motor within its 0.75 kW / 4.4 A rating, the integrated motor connector and automatic parameterization features are designed for the SIMOGEAR ecosystem. Using a third-party motor requires manual commissioning and may need a separate connector adapter.

How do the I/O variant suffixes (AA0, AB0, AF0) differ?

Within each power rating, the final suffix letter designates the I/O configuration variant. All variants share the same core drive hardware and ratings. The suffix determines the digital I/O count, fail-safe input arrangement, and whether certain I/O points are pre-configured as inputs or can be parameterized as inputs or outputs. Consult the G115D operating instructions for the exact I/O mapping of each suffix variant to match your conveyor control topology.

What derating applies at high ambient temperatures?

The G115D FSA frame is rated for full load current up to 40 °C ambient. Between 40 °C and the maximum 55 °C operating limit, the output current derates linearly. At 50 °C, expect approximately 85% of rated current. For installations above 1000 m altitude, additional derating applies per IEC 61800-2. The FSA variant uses natural convection cooling — no fan to maintain or replace — which contributes to its compact dimensions and long service intervals.
