At 0.55 kW (1.7 A rated, 3.4 A overload), the 6SL3520-1XE40-5AF0 matches the SIMOGEAR 2KJ8 geared motors in the 0.37–0.55 kW class — the motor range that drives individual curve-roller and transfer-zone conveyor sections in e-commerce sortation systems. The FSA frame dissipates 37.6 W power loss through natural convection, running silent and fanless at operator-accessible mounting height.

What distinguishes the 0.55 kW from the 0.37 kW in conveyor design?

The 0.37 kW drive handles straight-run roller beds with uniform product flow. The 0.55 kW steps up for zones where the mechanical load is higher: 90-degree transfers, merge sections where two infeed lines combine, or inclined sections with a modest gradient. The difference in practice is the overload margin — at 0.55 kW (1.7 A rated), the drive has more headroom before hitting the 200% overload ceiling when product weight varies or rollers accumulate debris. The 1XE gland entry and C2 filter are identical to the 0.37 kW unit — the only difference is the power stage, which costs marginally more in exchange for the extra overload headroom.

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. The 350 Ω integrated braking resistor supports dynamic braking for frequent start/stop cycles. 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.
