The Siemens 6SL3520-1XA60-7AB0 is the PROFINET-enabled 0.75 kW variant in the SINAMICS G115D distributed drive family, carrying the 1XA60 catalog designation — the newly discovered lower-power half of the 1XA6x sub-series. At 2.2 A rated and 4.4 A overload, it delivers PROFINET IO, EtherNet/IP, and PROFIsafe on a single Ethernet interface, with the integrated 2-port switch enabling daisy-chain line topology.

Why PROFINET at 0.75 kW?

The 0.75 kW FSA drive powers the lightest conveyor sections — short belt segments, right-angle transfers, and low-speed roller beds. These are the most numerous drives in any distribution center. If the site has standardized on PROFINET for all drives regardless of power, the 1XA60-7AB0 maintains that uniformity at the lowest power tier. The 2-port switch topology is especially valuable at 0.75 kW: with dozens of these drives on a single conveyor line, daisy-chaining eliminates the need for a field switch at every few drive positions — each drive passes the Ethernet frame to its neighbor. PROFIsafe on the same cable eliminates separate safety wiring for STO, which would otherwise dominate the wiring budget at this drive density.

1XA60-7AB0 vs 1XA00-7AB0 vs 1XA20-7AB0

All three PNs identify the same 0.75 kW FSA PROFINET drive. The 1XA60 (1XA6x sub-series), 1XA00 (1XA0x sub-series), and 1XA20 (1XA2x sub-series) catalog codes are parallel commercial designations — same hardware, same performance, different sub-series codes. Selection depends on which PN the Siemens distributor stocks, not on any technical specification difference.
