Light-duty sections — transfer rollers, diverters, small gates — usually get the cheapest starter available. The 0.55 kW G115D PROFINET variant is the case for spending a little more: control, diagnostics, and protection that a starter cannot offer.

When is a 0.55 kW drive worth networking?

When the section matters to throughput or safety. On PROFINET or EtherNet/IP (AF0), the 0.55 kW drive reports running state, current, and faults to the controller, and speed can be trimmed from the HMI without touching hardware. Zones that only need start/stop stay cheap; zones that need visibility get it.

What does it add over a starter?

Soft acceleration that spares belts and small gearboxes, electronic overload instead of a thermal relay, and a speed setpoint instead of a fixed frequency. The FSA frame is fanless and IP65/66, so it mounts anywhere on the machine; 1.7 A rated output with 200% overload for 3 s covers the duty.
