Not every conveyor segment is destined for the network diagram — maintenance spurs, test benches, and short transfer sections often run for years on a local potentiometer and a start button. The 2XH60-7AB0 build of the SINAMICS G115D is the 0.75 kW drive for exactly that service: local I/O control without fieldbus, local/remote switching on the housing, and everything needed to survive life next to the belt.

What does a standalone section actually need from its drive?

Reliable starting, protection, and nothing to configure. This build delivers 2.2 A rated in LO duty (4.4 A HO) with 200% for 3 s on belt starts, sensorless vector control for constant torque across the speed range, and the integrated 24 V PSU to power the local controls — no separate supply, no parameter server, no network stack to commission. The local/remote switch means a technician can run the section by hand during maintenance and hand it back to the interlock without rewiring.

Why order the AB0 build instead of keeping a fieldbus version unused?

Because the fieldbus letter is not a free option on this platform — it is built into the order number. Stocking the 7AB0 for standalone sections keeps the spares honest: the housing (380 x 216 x 129 mm, IP65/66), the C2 filter, the gland wiring and the ratings are identical to the 7AA0 and 7AF0 builds, so the mechanical swap is unchanged, and no one pays for a communication port that will never be terminated.
