When a 7.5 kW conveyor section must run without a control cabinet, what drives it?

The 6SL3520-2XB47-5AF0 is a SINAMICS G115D distributed drive: converter and SIMOGEAR geared motor in one wall-mounted unit at IP66, 7.5 kW at 200% overload for 3 s. It bolts to the machine frame — no enclosure, no long motor cable back to a central drive — which cuts cable cost and removes the cabinet-cooling load for the whole line.

If the line runs a networked safety chain, how is STO wired?

PROFINET with PROFIsafe is onboard, so the drive carries an F-address and joins the SIMATIC/TIA safety network directly — STO over the fieldbus, no separate safety relay. A single cable break on a ring topology is detected and the drive faults safe without relying on network messaging.

What overload and braking does a 7.5 kW belt motor need?

Belt 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, in a 425 x 180 x 169 mm FSC housing rated -30 to +55 C.
