What makes the 1.5 kW FSA the most compact fully equipped G115D configuration?

The FSA frame (380x156x129 mm, 5.6 kg) is the smallest wall-mounted enclosure in the G115D range. At 1.5 kW — the highest power available in FSA — the AF0 variant packs PROFIsafe safety communication, an integrated C2 line filter, PROFINET/EtherNet/IP dual-port communication, and a 180 V DC brake output into an IP66-rated enclosure smaller than a standard laptop bag. This is the drive you specify when the conveyor section's mechanical power demand is modest (light-duty roller beds, small belt conveyors, diverters) but the electrical and safety architecture demands full-featured drives at every position. The FSA frame is fanless — all heat dissipation is via natural convection through the rear mounting surface and finned enclosure — so there are zero moving parts in the entire drive assembly.

When does it make sense to specify AF0 at the 1.5 kW FSA level?

Three scenarios justify the AF0 variant at this power rating: (1) a homogeneous safety architecture where every drive on the PROFINET network uses PROFIsafe, regardless of power — mixing F-DI and PROFIsafe on the same network is technically possible but architecturally inconsistent, and some end users mandate uniform safety communication; (2) retrofitting an existing conveyor line where running new F-DI wiring to each drive position would be more expensive than the AF0 cost premium — the PROFIsafe signal rides on the PROFINET cable already present; (3) conveyor sections in hygienic or washdown environments where minimizing cable penetrations into the drive enclosure is a cleanliness requirement — each F-DI cable gland is a potential moisture ingress point, and PROFIsafe reduces the required cable entries per drive from three (power, communication, safety) to two (power, communication).

How does the 1.5 kW FSA thermal design differ from the FSB frame?

The FSA heatsink is a single-piece aluminum extrusion integrated into the rear of the enclosure, dimensioned for the lower absolute power loss of the FSA power range (up to 67 W at 1.5 kW). Natural convection airflow is sufficient at up to 40C ambient. Unlike the FSB frame which transitions to forced cooling at 4 kW, the entire FSA power range — 0.37 kW through 1.5 kW — is fanless. The 1.5 kW point uses the largest IGBT modules in the FSA family and has the highest power density in the FSA enclosure, but the thermal design is validated for continuous duty at rated current without derating. The practical implication: a 1.5 kW FSA AF0 and a 3 kW FSB AF0 share identical feature sets, but the FSA variant saves approximately 2.2 kg of weight and 45 mm of enclosure width per drive position.

Frequently Asked Questions

Can the 1.5 kW FSA be daisy-chained with FSB drives on the same power feeder?

Yes. The FSA and FSB frames use compatible daisy-chain power connectors. A 400 V feeder can supply an FSB drive at the head of the line, with FSA drives connected downstream. The total feeder current — sum of all drives' input currents — must not exceed the connector and cable rating of the first drive in the chain.

Is the FSA AF0 compatible with the same SIMOGEAR 2KJ8 geared motors as the FSB variants?

Yes. All G115D wall-mounted converters, regardless of frame size, are designed for operation with SIMOGEAR 2KJ8 geared motors in frame sizes 71 through 132. The motor selection is determined by the application's torque and speed requirements, not by the converter frame size.
