The 6SL3520-1XK01-1AF0 bridges mid-power FSA distributed drive requirements with PROFINET network integration: 1.1 kW at 3.1 A continuous, 1/3-phase wide-voltage input, and the full PROFIdrive telemetry stack. At 1.1 kW, this drive matches IE3/IE4 motors in the 0.75-1.1 kW range — a common size class for modular conveyor segments, rotary tables, and packaging infeeds where each station runs at modest power but the line controller needs per-drive visibility for coordinated motion and diagnostics.

1/3-phase flexibility at 1.1 kW

The wide-voltage input stage auto-detects the supply configuration at power-up. For an OEM exporting a packaging machine to markets where single-phase 230 V distribution is common, this drive eliminates the need to stock separate single-phase and three-phase part numbers. The machine's control transformer steps 230 V to 400 V, the drive rectifies it, and the output stage delivers 3.1 A to the motor — the motor never knows the difference. This single-PN flexibility is the 1XK series' defining advantage over the 3-phase-only 1XH series.
