The SINAMICS G115D is a distributed wall-mounted drive series for horizontal conveyor applications. The 6SL3520-0XA61-5AB0 delivers 1.5 kW at 4.1 A rated output (8.2 A overload) in the compact FSA frame, measuring 380 × 156 × 129 mm. This is the highest power rating available in the FSA frame — the ceiling of what natural convection cooling can handle in this enclosure size.

What makes the FSA frame suited for light conveyor sections?

The FSA frame is the smallest and lightest G115D wall-mounted variant, designed for decentralized mounting directly at the motor on light-duty conveyor zones. Natural convection cooling eliminates fans and filters — no moving parts to service, no airflow path to keep clear, and full IP65/66 protection maintained. With a rated motor cable length of 15 m and a 350 Ω integrated braking resistor, FSA drives cover short-zone accumulation conveyors, diverters, and light transfer sections.

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 RFI filter meets Category C2 requirements.
