The 6SL3520-1XK01-1AA0 is the hardwired I/O baseline at 1.1 kW: four digital inputs, one analog input, 180 V DC brake output, and the full 1/3-phase wide-voltage input stage in the FSA frame. At 3.1 A continuous output, this variant serves the straightforward conveyor drive application — a PLC sends a 0-10 V speed reference over two wires and a run command over a third, and the drive executes. No network configuration, no device naming, no GSDML file. The drive ships with PROFINET and EtherNet/IP ports on board for future integration, but commissioning on day one requires only a screwdriver and a multimeter.
