The SINAMICS G115D 6SL3520-1XA20-3AA0 delivers 0.37 kW in the G115D wall-mounted drive family, using I/O Control for direct digital and analog signal integration. Its FSA frame mounts at the motor — no control cabinet required. Natural convection cooling and IP65 protection make it a fit-and-forget solution for light conveyor zones in intralogistics and packaging lines.

When should I choose I/O Control over a fieldbus?

The AA0 variant accepts speed setpoints via analog input (0–10 V or 4–20 mA) and discrete commands (start/stop, direction) via digital inputs. This is the right choice when the upstream controller uses basic PLC I/O modules without a fieldbus network — no gateway, no network configuration, just wire and run. The trade-off: each signal needs its own conductor, so total wiring grows with I/O count. For installations with more than a few drives on the same line, a fieldbus variant (AS-Interface or PROFINET) reduces total wiring.

What safety functions are built in?

Safe Torque Off (STO) is integrated via fail-safe digital input (F-DI), achieving SIL2/PLe without an external safety relay. The F-DI input accepts a 24 V signal from a safety PLC or safety relay. When de-energized, the drive cuts motor torque within milliseconds — safe for maintenance. No separate safety contactor is needed.

How does it fit into a conveyor system?

At 0.37 kW, this drive targets the lightest conveyor zones — small roller beds, belt curves, diverters, and accumulation zones where full-speed torque demand is modest. The 0–550 Hz output range supports both low-speed jogging for setup and full-speed operation. Combined with SIMOGEAR 2KJ8 geared motors, it forms a complete drive package that bolts directly to the conveyor frame.
