The 6SL3520-1XH61-5AA0 is the hardwired-I/O variant at the top of the G115D FSA range: 1.5 kW, 8.2 A, fanless cooling, with the AA0 standard I/O interface. It delivers the highest power available in the compact FSA frame through the simplest control path — four digital inputs and one analog speed reference input.

1.5 kW FSA with hardwired I/O — the OEM standard

For conveyor OEMs building standardized modules — a belt section, a roller bed, a transfer car — the 1.5 kW FSA is often the default drive size for the main conveyor sections. The AA0 interface keeps integration simple: the upstream PLC sends a run command and a 0–10 V speed reference over discrete wiring. No fieldbus configuration, no network addressing, no additional engineering tool. The drive's DIP switches set the analog signal type; everything else is pre-wired at the factory. For an OEM shipping dozens of identical conveyor modules, this is the configuration that minimizes on-site commissioning time.

1XH61 AA0 — the FSA ceiling, simply controlled

The 1XH61 sub-code identifies this hardware revision of the 1.5 kW FSA platform. At 8.2 A, it is the step below the 2.2 kW FSB — the last G115D that fits in the 380 mm FSA housing, the last that cools without a fan, and in AA0 trim, the variant that keeps the control architecture as simple as the cooling method.
