The SINAMICS G115D 6SL3520-0XH61-1AF0 stands out with dual-protocol support — PROFINET and EtherNet/IP in a single F-code drive. This 1.1 kW wall-mounted unit eliminates the need for protocol gateways when a production line mixes Siemens and Rockwell controllers, or when an end user standardizes on EtherNet/IP while the OEM prefers PROFINET. Rated IP65/IP66, it mounts directly on the machine with no control cabinet.

Why choose the dual-protocol variant?

In mixed-automation environments — automotive lines with Siemens PLCs on one cell and Rockwell on the next, or intralogistics systems where the integrator uses PROFINET but the end user's plant network is EtherNet/IP — the 1AF0 variant adapts without hardware changes. This reduces spare parts inventory and simplifies migration between controller platforms. All G115D technology functions — conveyor-specific macros, encoderless vector control, and integrated STO safety — remain available regardless of which protocol is active.

How does commissioning differ from the single-protocol models?

Commissioning follows the same workflow: DIP switches for basic motor data, SINAMICS SAM web server for wireless setup, or TIA Portal with Startdrive for full parameterization. The protocol selection (PROFINET or EtherNet/IP) is configured during setup — the drive detects the active network and auto-negotiates. The integrated 24 V DC PSU powers sensors and I/O without an external supply.

Frequently Asked Questions

Can I switch protocols after installation?

Yes. The protocol is selected via parameter setting, not hardware — reconfiguration is possible in the field without replacing the drive. This future-proofs machines that may be redeployed to different plants with different network standards.

What motors work with the 1AF0?

Same as all G115D wall-mounted units: SIMOGEAR 2KJ8 geared motors with IE3 asynchronous or IE4 synchronous reluctance motors. The 1.1 kW rating supports motor speeds from 300 to 1500 rpm (1:5 range) or 300 to 3000 rpm (1:10 range) depending on motor type.
