The SINAMICS G115D 6SL3520-0XH00-7AB0 is the 0.75 kW wall-mounted distributed drive — the second-smallest variant in the SINAMICS G115D series. In the compact FSA frame (380 × 216 × 129 mm) with fanless natural convection cooling, it delivers 2.2 A rated output current with 200% overload for 3 seconds — sized for individual zone rollers, short transfer belts, and light packaging line infeeds. PROFINET with PROFIsafe brings STO over Ethernet even at this power level, enabling the same safety architecture across the entire conveyor line from the smallest zone roller to the main sortation drive.

What does 0.75 kW cover vs. 0.55 kW and 1.1 kW?

At 0.55 kW (1.7 A rated), the drive handles the lightest individual zone rollers — one or two rollers per zone, small packages, low-friction belt sections. The 0.75 kW steps up to 2.2 A, covering standard zone roller sections of 2–4 rollers or short belt conveyors under 3 meters with moderate product weight. For sections approaching 4–5 meters or carrying heavier packages, the 1.1 kW variant (3.1 A) provides additional headroom. All three share the same FSA frame and mounting dimensions — upgrading power requires no mechanical redesign.

Motor compatibility and installation

Direct mounting to SIMOGEAR 2KJ8 geared motors in IE3 or IE4 efficiency classes with integrated 400 V AC brake control. Encoderless vector control in V/f and sensorless modes. Dual-protocol PROFINET and EtherNet/IP supports mixed-vendor PLC environments. The FSA compact housing fits tight conveyor frame spaces where larger FSB and FSC frames cannot.
