The Siemens 6SL3520-0XC01-1AA0 is the I/O Control variant in the 0XC connector family of the SINAMICS G115D wall-mounted distributed drive platform, rated at 1.1 kW in the compact FSA frame (380 × 156 × 129 mm). With 3.1 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 for light conveyor sections in facilities using C-connector cable sets.

What does I/O Control mean in the 0XC FSA range?

The AA0 suffix designates I/O Control — Siemens' term for the hardwired command interface. Four programmable PNP digital inputs accept speed, direction, and enable signals from pushbuttons, relays, or a basic PLC output card. At 1.1 kW, this covers small belt turns, diverters, and singulation gates. The drive delivers the full G115D motor control suite — V/f, V/f with FCC, sensorless vector control — identical to the PROFINET variant. The C-connector means this drive shares cable sets with any 0XC02/03/04 drives at higher power levels on the same line. Commission via Mini-USB with TIA Portal Startdrive or SD card; once configured, only 24 V DC I/O signals are needed for operation.

How does this compare to I/O Control variants in 0XD or 1XB at 1.1 kW?

Electrically identical — same 3.1 A rated / 6.2 A overload, same I/O Control interface. All three are FSA frame. The difference is the connector: 0XC01 uses C-type, 1XB41/1XB01 use B-type, 0XD00 uses D-type. Choose based on your facility's cable standard. If you standardize on C-connector across the line, the 0XC01-1AA0 is your 1.1 kW I/O Control option.

What motor types are supported?

The drive supports IE3 asynchronous motors, IE4 synchronous reluctance motors, and SIMOGEAR geared motor combinations up to 1.1 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

Can this drive be upgraded to PROFINET later?

No. The communication interface is hardware-defined at order. If network integration is a possibility, select the AF0 variant — it provides both PROFINET and digital input fallback.

Is an external braking resistor required?

The integrated 180 V DC brake chopper is sufficient for 1.1 kW conveyor applications. An external braking resistor (minimum 200 Ω for FSA) is rarely needed at this power level.
