The 6SL3520-1XK04-0AB0 is the AB-suffix configuration of the 4 kW G115D in the FSB frame — the highest power available in this frame size. Electrically identical to the 0AF0 at 10.2 A continuous and 20.4 A peak (200% for 3 seconds), the AB variant provides a specific I/O and communication configuration suited to distributed conveyor and material handling installations where the AB feature mix aligns with the control architecture.

The 425 × 180 × 134 mm IP65/IP66 enclosure mounts at the point of use — no cabinet. An integrated C2 EMC filter covers industrial compliance, an internal braking resistor handles regenerative energy, and STO SIL 2 via Profisafe provides functional safety. IE2/IE3/IE4 motor support, SAM web-server diagnostics, and 0–550 Hz V/f or 0–240 Hz vector output are standard across the G115D family.
