The 6SL3520-0XM00-5AA0 is the basic 0.55 kW variant of the SINAMICS G115D distributed drive. It targets cost-sensitive conveyor applications where the installation already provides EMC filtering and standard STO via F-DI is sufficient — delivering the full G115D mechanical robustness and control capability without the integrated C2 filter or PROFIsafe overhead.

What control modes does the G115D support?

All G115D variants share the same control firmware, supporting V/f control (linear, square-law, and parameterizable curves), V/f with Flux Current Control (FCC) for improved low-speed torque, V/f ECO for energy-optimized operation, and sensorless vector control for precise speed regulation without an encoder. A PID technology controller is built in for closed-loop process control — pressure, flow, or tension regulation without an external PLC. Pulse frequency is adjustable from 4 to 16 kHz in 2 kHz steps for acoustic noise tuning.

How does the G115D integrate with SIMATIC control systems?

The drive connects to any PROFINET or EtherNet/IP controller. For SIMATIC users, pre-configured TIA Portal macros and function blocks accelerate commissioning — the drive is auto-detected on the network and configured through the Siemens Startdrive engineering tool. A web server module is available for wireless commissioning via tablet or smartphone without software installation.

Frequently Asked Questions

What is the difference between the entry-level AA0 and the mid-range AB0?

The sole hardware difference is the integrated C2 EMC line filter. The AB0 includes it; the AA0 does not. All other hardware — power stage, control electronics, PROFINET/EtherNet/IP interface, STO via F-DI, fanless FSA enclosure — is identical. If your site-level EMC strategy already handles conducted emissions, the AA0 saves cost with no functional compromise.

Does the G115D support energy regeneration?

No. The G115D does not support regenerative braking back to the mains. For braking, it uses an integrated braking resistor (350 Ω, 10 W continuous for FSA) with an option for an external braking resistor (min. 200 Ω for FSA). The mechanical brake output is 180 V DC.
