The 6SL3520-0XB41-5AB0 delivers 1.5 kW in FSA frame (380 × 156 × 129 mm, 5.77 kg) with B-connector and AB0 Standard I/O — the highest FSA power rating available with hardwired terminal control. Rated for 4.1 A continuous output (HO) at 380–480 V three-phase, it suits decentralized conveyor applications where a compact IP65 on-machine drive with simple PLC I/O wiring fits the control architecture better than a fieldbus solution.

As the top FSA power rating, this drive represents the ceiling of what natural convection cooling can handle in the compact 380 × 156 × 129 mm enclosure. The next step up — 2.2 kW — requires the larger FSB fanless frame (425 × 180 × 134 mm, 7.12 kg). The AB0 Standard I/O variant uses dedicated terminal connections for run/stop, direction, speed reference, and fault output — no GSDML file, no network switch, no IP address assignment. Combined with IP65/IP66 sealing and IE2/IE3/IE4 motor compatibility, the 0XB41-5AB0 provides a self-contained motor control solution that mounts directly at the conveyor zone, eliminating control cabinet space and motor cable runs.
