The 6SL3520-0XN02-2AA0 is the 2.2 kW I/O Control G115D in the fanless FSB frame — the simplest communication option at the G115D frame transition point. It delivers 5.9 A rated (11.8 A overload) from a 380–480 V 3-phase supply, controlled through hardwired digital and analog I/O terminals with no fieldbus and no cooling fan.

Why I/O Control at the 2.2 kW transition?

2.2 kW is where the G115D leaves the FSA frame — below this, the FSA enclosure (380 × 216 × 129 mm) handles the heat load with natural convection. At 2.2 kW, the drive moves to the FSB fanless enclosure (425 × 180 × 134 mm, 7.12 kg) for adequate passive cooling. The I/O Control AA0 variant at this power level serves two distinct scenarios. First, the retrofit: an existing 2.2 kW cabinet drive is being replaced with a distributed drive mounted on the machine frame, and the plant's control wiring (start/stop pushbuttons, speed potentiometer, fault lamp) is already in place — the G115D AA0 drops into this wiring environment without network changes. Second, the OEM standalone module: a conveyor section shipped with its own local control station, running at fixed or preset speeds, where adding a fieldbus would add engineering cost without operational benefit. For plants planning to network their drives, PROFINET (XN02-2AB0) and AS-Interface (XN02-2AF0) variants are available at the same 2.2 kW rating.

Fanless FSB at 2.2 kW — passive cooling still works

The fanless FSB at 2.2 kW operates without a fan — the larger aluminum enclosure provides sufficient natural convection surface area to keep the power stage within rated temperature limits up to 40°C ambient. The fan threshold sits between 3 kW and 4 kW. This means the 2.2 kW FSB has zero mechanical wear components: no fan bearings, no fan blades, no dust ingestion path through a fan intake. The 24 V DC control supply draws 250–290 mA — half the draw of fan-cooled variants. For dusty or fibrous environments, fanless operation at 2.2 kW is a meaningful reliability advantage.

XN02: intermediate catalog generation

XN02 is the intermediate-generation catalog code; XH22 is the current designation. Both are the same 2.2 kW fanless FSB hardware with identical ratings and dimensions. When ordering a replacement, XH22-2AA0 is the current-catalog equivalent.

Frequently Asked Questions

How is the speed setpoint adjusted?

Via a 0–10 V analog input (potentiometer or PLC analog output), 4–20 mA current loop, or digital input presets configured during commissioning. The drive does not require a keypad for runtime speed control.

Can I upgrade to PROFINET or AS-Interface later?

No. The AA0 (I/O Control), AF0 (AS-Interface), and AB0 (PROFINET) variants are factory-configured hardware — the communication interface is not field-upgradable. Select the variant that matches your control architecture at purchase.

What is the 24 V DC current draw?

250–290 mA for the fanless FSB — roughly half the draw of fan-cooled variants. Budget this per drive when sizing the control panel 24 V DC power supply for multi-zone conveyor systems.
