The 6SL3520-0XK00-3AA0 is the 0.37 kW entry-level SINAMICS G115D in the standard AA0 I/O configuration. At the lowest power tier in the FSA frame, it is sized for light conveyor sections, small roller beds, and auxiliary material handling functions — gate actuators, diverter arms, empty-tote returns — where a larger drive would be mechanically oversized. The drive mounts directly on the machine frame alongside a SIMOGEAR geared motor, eliminating the cabinet space and long cable runs of a traditional VFD installation.

What is the difference between the AA0, AB0, and AF0 I/O configurations?

All three suffix codes share identical core drive parameters — 0.37 kW output, 1.23 A rated current, 380–480 V 3AC supply, 0–550 Hz frequency range, and FSA frame dimensions. The suffixes denote the I/O interface configuration: the type and arrangement of digital inputs, digital outputs, and communication connectors populated on the unit. Selection between AA0, AB0, and AF0 is a field-wiring compatibility decision — the specific pinout and terminal assignments should be confirmed against the G115D operating manual for the target installation. None of the three suffixes affect the drive's electrical performance or mechanical footprint.

How does distributed mounting work for small conveyor sections?

Traditional conveyor automation places all VFDs in a central control cabinet, with shielded motor cables running from the cabinet to each motor along the conveyor line. The G115D flips this architecture: the converter mounts directly on the machine frame near the motor, connected via a short cable. For light-duty sections using the 0.37 kW variant, this distributed approach is especially compelling — the sections are often remote from the main cabinet, and the cost of running long shielded cables to a 0.37 kW motor can exceed the cost of the drive itself. With IP65 and an operating range of −30 °C to +40 °C, the G115D handles unheated logistics areas and washdown zones without additional enclosures.

Frequently Asked Questions

Can this drive control a motor without a PROFINET PLC?

Yes. The onboard digital I/O supports hardwired start/stop, direction, and fixed-speed selection for standalone operation. PROFINET and EtherNet/IP are available for networked applications but are not required for basic conveyor control. Full parameterization and diagnostics do need a network connection via TIA Portal or a compatible engineering tool.

What motor types are compatible with the 0.37 kW G115D?

The G115D is engineered for direct attachment to SIMOGEAR 2KJ8 geared motors equipped with IE3 three-phase asynchronous motors or IE4 synchronous reluctance motors. The drive auto-adapts to the connected motor during TIA Portal commissioning using the electronically identifiable gearbox data. Maximum recommended motor cable length is 15 m at the default 4 kHz pulse frequency.
