The Siemens 6SL3520-0XE00-3AF0 is the full-featured AF0 variant of the SINAMICS G115D at the 0.37 kW (0.50 hp, 1.3 A) entry power level in the compact FSA frame. It brings daisy-chain power and communication looping plus a local remote panel to the smallest G115D — purpose-built for accumulation conveyors where drive density is highest and reducing per-drive cabling yields the largest installation savings.

Frequently Asked Questions

Is the AF0 worth the premium at 0.37 kW?

It depends on drive density. On an accumulation conveyor with 15–20 zones, each 2–3 metres apart, the AF0's daisy-chain topology eliminates 15–20 individual power drops and an Ethernet switch. The hardware savings typically exceed the AF0 premium after about 5 drives. For a single standalone 0.37 kW conveyor, the AA0 variant is the cost-effective choice.
