The Siemens 6SL3520-1XC01-5AA0 is the I/O Control variant in the 1XC connector system of the SINAMICS G115D wall-mounted distributed drive family — the "1X"-prefix C-connector code system. Rated at 1.5 kW in the compact FSA frame (380 × 156 × 129 mm) with 4.1 A rated output (High Overload), 380–480 V 3-phase supply, and C-type connector, it provides hardwired digital input control with the AA0 terminal configuration — the third communication variant confirmed in the 1XC01 sub-series, alongside AF0 (PROFINET) and AB0 (Standard I/O).

What does I/O Control mean in the 1XC system?

The AA0 suffix provides four programmable PNP digital inputs for speed, direction, and enable — connected to pushbuttons, relays, or a basic PLC output card. The drive delivers the full G115D motor control suite — V/f, V/f with FCC, sensorless vector control — identical to the PROFINET variant in performance. The C-connector means this drive shares cable sets with any 0XC or 1XC drive on the same line. Commission via Mini-USB with TIA Portal Startdrive or SD card; day-to-day operation requires only 24 V DC I/O signals.

What motor types are supported?

The drive supports IE3 asynchronous motors, IE4 synchronous reluctance motors, and SIMOGEAR geared motor combinations up to 1.5 kW. Control modes: V/f (0–550 Hz), V/f with FCC, sensorless vector control (0–240 Hz). Integrated 180 V DC brake control. FSA frame: natural convection cooling, IP66 / UL Type 4X.

Frequently Asked Questions

Is an external braking resistor required?

The integrated 180 V DC brake chopper is sufficient for most 1.5 kW conveyor applications. An external braking resistor (minimum 200 Ω for FSA) is only needed for decline sections or high-inertia loads with frequent stops.
