The Siemens 6SL3520-0XD00-5AA0 is the I/O Control variant of the SINAMICS G115D wall-mounted distributed drive family in the 0XD connector configuration, rated at 0.55 kW — the entry-level power rating in the G115D FSA range. With 1.7 A rated output (High Overload) and a 380–480 V 3-phase supply, it targets the lightest conveyor sections: small roller beds, belt turns, and singulation modules where hardwired digital input control is sufficient and a fieldbus network is not required.

What does I/O Control mean at 0.55 kW?

I/O Control is Siemens' term for the hardwired command interface. Four programmable PNP digital inputs accept 24 V DC speed, direction, and enable signals directly from pushbuttons, relays, or a basic PLC output card. Commissioning is via Mini-USB with TIA Portal Startdrive or via SD card — once parameters are set, day-to-day operation requires only the hardwired I/O and a 24 V DC control supply (250 mA typical for FSA). The setpoint resolution is 0.01 Hz, enabling precise conveyor speed trimming even at the lowest power level.

What motor types are supported?

The drive supports IE3 asynchronous motors, IE4 synchronous reluctance motors, and SIMOGEAR geared motor combinations up to 0.55 kW. Control modes include V/f, V/f with FCC, and sensorless vector control. Output frequency: 0–550 Hz (V/f), 0–240 Hz (vector). Overload: 200% (3.4 A) for 3 seconds, 150% for 57 seconds. Integrated 180 V DC brake control manages an electromechanical motor brake directly.

Frequently Asked Questions

When is 0.55 kW sufficient?

For small conveyor sections — belt turns, diverters, singulation modules — where the steady-state mechanical load is under approximately 0.75 hp. If the application involves frequent start-stop cycles under load, consider the 0.75 kW (2.2 A) variant for additional thermal headroom, even if the steady-state load is below 0.55 kW. The FSA mechanical package is identical across all power ratings (380 × 156 × 129 mm), so upgrading costs only the drive procurement difference — no mechanical redesign.

How does the 0XD connector differ from 1XB?

Both are G115D FSA-frame drives with identical electrical ratings. The difference is the connector system: 0XD (position 10 = D) and 1XB (position 10 = B) use different connector configurations. Choose the variant that matches your available pre-assembled cable sets or existing fleet standard. Both share the same mechanical footprint and can be mixed on the same conveyor line.
