At 1.5 kW (4.1 A rated, 8.2 A overload), the 6SL3520-1XE41-5AF0 is the highest-power drive in the compact FSA frame — the ceiling of what the 380 × 156 × 129 mm natural-convection envelope can thermally sustain at 67 W power loss. For conveyor OEMs standardizing on the FSA mounting footprint, this is the most capable drive available without stepping to the larger FSB platform.

What can you drive at the FSA power ceiling?

The 4.1 A continuous output covers 1.5 kW 3 AC induction motors at 400 V — the largest motor routinely deployed on individual zone-roller conveyor sections. Paired with a SIMOGEAR 2KJ8 helical geared motor at 1.5 kW, the combination delivers rated torque from standstill through the 200% overload curve. The 1XE configuration adds gland-type cable entry with IP66 sealing and an integrated C2 RFI filter — the same filter and sealing standard as the 7.5 kW FSC drive, just in a smaller package. For an OEM building a conveyor line where every drive position must meet IP66 washdown requirements, the 1XE FSA drives deliver the same environmental rating as the largest units on the line.

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 (10 W continuous) supports dynamic braking. 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.
