The 6SL3520-0XA60-5AB0 provides PROFINET control and STO safety for 0.55 kW conveyor motors (1.7 A rated, 3.4 A overload). Safe Torque Off via F-DI or PROFIsafe means the drive can participate in zone-level safety functions — a light curtain break stops this zone without killing power to the entire line.

How does STO work in a distributed conveyor architecture?

Each G115D drive has dual-channel STO inputs. When a safety device (light curtain, e-stop, gate switch) triggers, STO removes torque from the motor within milliseconds while keeping the drive powered and on the PROFINET network. Diagnostics report exactly which zone triggered — no hunting for a tripped contactor in a remote cabinet. After clearing the safety condition, the drive restarts without a power cycle.

Key specifications

The drive operates from a 3 AC 380–480 V supply (45–66 Hz) with an output frequency range of 0–550 Hz. High-overload capability delivers 200% for 3 seconds and 150% for 57 seconds. The built-in RFI filter meets Category C2 requirements.
