At 1.5 kW (4.1 A rated, 8.2 A overload), the 6SL3520-1XE41-5AB0 matches the largest SIMOGEAR 2KJ8 geared motors routinely specified for individual conveyor zone drives. The 4.1 A continuous output covers 1.5 kW motors at 400 V with full torque from standstill — the FSA frame's 350 Ω braking resistor handles the regenerative pulses from frequent start/stop indexing without an external brake chopper.

Which SIMOGEAR motors does the 1.5 kW G115D support?

Siemens SIMOGEAR 2KJ8 helical geared motors in the 1.1–1.5 kW range with IE2 efficiency pair directly with the 1XE41-5 FSA drive. The motor cable run is short — the wall-mounted drive sits within a meter of the motor on the conveyor frame, eliminating the long shielded cable that a central-cabinet VFD would require. The G115D's sensorless vector control maintains speed accuracy under changing load without an encoder — important for accumulation conveyors where backpressure raises motor torque unpredictably. Combined with the 1XE gland entry's IP66 compression seal and the integrated C2 filter, the 1.5 kW FSA is a self-contained drive node: power in, motor out, PROFINET in — no cabinet, no external filter, no encoder cable.

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.
