At 3 kW (7.7 A rated, 15.4 A overload), the 6SL3520-0XA23-0AF0 targets the most common mid-range conveyor motor size. The 7.7 A continuous output matches SIMOGEAR 2KJ8 geared motors in the 2.2–3 kW class — the high-overload curve (200% for 3 s, 150% for 57 s) covers the locked-rotor starting current of a fully loaded incline belt without tripping.

Which motors pair with the 3 kW G115D FSB?

Standard 3 AC induction motors in the 2.2–3 kW range at 400 V draw 5–7.7 A full-load — well within the 7.7 A continuous rating. The drive supports both V/f and sensorless vector control modes. For conveyor applications where precise speed holding under varying load matters — merge sections, accumulation zones — vector control compensates for slip and maintains setpoint within ±0.5% across the load range. The convection-cooled FSB envelope (425 × 180 × 134 mm) handles 125.8 W power loss without a fan, suitable for intermittent-duty conveyors and ambient temperatures up to +40 °C.

Key specifications

The drive operates from a 3 AC 380–480 V supply (45–66 Hz) with an output frequency range of 0–550 Hz. High-overload capability delivers 200% for 3 seconds and 150% for 57 seconds. Integrated PROFINET and Ethernet IP interfaces connect directly to SIMATIC controllers. The built-in C2 RFI filter meets EN 61800-3 Category C2 conducted emission limits for industrial environments.
