When a distributed drive must satisfy a networked safety chain, how is STO wired?

PROFINET with PROFIsafe is onboard, so the 6SL3520-2XC00-3AF0 is a native node on a SIMATIC/TIA safety network with an F-address — STO is handled over the fieldbus and no separate safety relay is needed. A single cable break on a ring topology is detected and the drive faults safe without relying on network messaging. For lines already running PROFIsafe, this removes a cabinet-mounted safety relay and its wiring.

What overload does a 0.37 kW conveyor roller need?

Roller duty is intermittent, so the drive is rated 200% of current for 3 s and 150% for 57 s. An integrated braking resistor is standard, so decelerating a light belt section is handled without an external module, in a 380 x 156 x 129 mm FSA housing rated -30 to +55 C.

Where does the drive mount?

This G115D bolts directly to the machine frame at IP66 — no enclosure, no long motor cable back to a central drive. That cuts cable cost and removes the cabinet-cooling load for the whole line.
