The 6SL3520-0XK01-5AA0 is the highest-power variant in the FSA frame size of the SINAMICS G115D distributed wall-mounted frequency converter series. Rated at 1.5 kW with an 8.2 A output, this drive is purpose-built for horizontal conveyor systems where control cabinet space is unavailable or undesirable. Mounted directly on the machine frame alongside a SIMOGEAR geared motor, it eliminates the cabinet, long motor cables, and associated installation costs of a traditional centralized VFD architecture.

What makes the 1.5 kW FSA variant the right choice?

The FSA frame covers 0.37 kW to 1.5 kW in the G115D lineup. At 1.5 kW, this model delivers the maximum mechanical power available in the compact FSA enclosure — 380 mm wide, 156 mm high, and 129 mm deep. Compared to the 1.1 kW variant in the same frame, it provides 36% more continuous shaft power for conveyor sections with higher throughput demands while occupying the identical mounting footprint. The drive operates from a 3AC 380-480 V supply and outputs 0-550 Hz in V/f mode, covering the full speed range needed for typical material handling applications from slow crawl to high-speed transfer.

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 1.5 kW / 8.2 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.
