Some of the busiest sections on a line are also the least connected — gate sections, short transfers, maintenance spurs — and the 2XH61-5AB0 build of the SINAMICS G115D is the 1.5 kW answer for them: local I/O with local/remote switching, 4.1 A rated in LO duty (8.2 A HO), and the convection-cooled FSA housing that needs no fan service at all.

What does a 1.5 kW standalone section need from its drive?

Control without configuration, and protection without supervision. The local I/O set and the local/remote switch handle both: a technician can run the section by hand during maintenance, and the drive manages ramps, 200%/3 s belt starts and motor protection on its own parameters. The integrated 24 V PSU powers the local panel through the M12 ports, so the section installs with two cable entries and no separate control supply.

Where is the ceiling of the local-I/O concept?

Where the section starts reporting upward. Energy data, remote diagnostics and line synchronisation belong to the 5AA0 (AS-Interface) and 5AF0 (PROFINET/EtherNet/IP) builds, which share the identical 380 x 216 x 129 mm housing, the gland wiring scheme and the ratings. Until that day arrives, the AB0 build keeps the section independent — and the spares shelf one unit simpler, because nothing in its order number depends on a network existing.
