The SINAMICS G115D 6SL3520-0XH20-7AA0 is a 0.75 kW wall-mounted distributed drive with digital/analog I/O control — the most economical entry into decentralized drive technology. No fieldbus, no network configuration: wire the start signal, connect a speed potentiometer, and the conveyor zone runs. The IP65/IP66 FSA enclosure bolts directly to the machine frame.

When Is I/O Control the Right Choice for a 0.75 kW Conveyor Zone?

For a standalone conveyor zone that runs at a fixed speed — or changes speed based on a simple sensor input — I/O Control is simpler and more cost-effective than a fieldbus variant. The drive responds to digital inputs (start/stop, direction, fault reset) and an analog input (0–10 V or 4–20 mA speed reference), reporting status back via digital outputs. No AS-i master, no PROFINET controller, no IP addressing. This is particularly suited to OEM machine builders who ship standalone conveyor modules — the end user connects power and a few I/O wires, and the module is operational.

What Does the 0.75 kW Rating Cover?

With 4.4 A overload (2.2 A continuous) at 380–480 V 3-phase, this drive powers one or two short conveyor zones or a single roller drive unit via SIMOGEAR 2KJ8 geared motors. The 0–550 Hz output supports smooth start/stop ramping without mechanical shock. Integrated STO via F-DI provides safety-rated torque removal directly from the emergency stop circuit.
