The 6SL3520-1XD01-1AA0 is a D-connector SINAMICS G115D with the 1X catalog prefix — 1.1 kW in FSA frame (380 × 156 × 129 mm, natural convection) with AA0 I/O Control. Rated for 3.1 A continuous output (HO) at 380–480 V three-phase, IP65 sealed. AA0 provides basic terminal-based control: digital inputs for start/stop and fixed-speed selection, analog input for speed reference — the simplest control path for standalone conveyor zones. The D-connector cable entry provides a distinct installation geometry compared to B-connector and C-connector alternatives, with no electrical performance difference at equivalent power and communication variant.

Why choose D-connector over B-connector or C-connector at 1.1 kW?

At 1.1 kW FSA, the G115D is now available with all three connector types: B-connector (1XB41/0XB41), C-connector (1XC01/0XC01), and D-connector (1XD01). The three connectors differ in cable entry geometry, termination style, and installation envelope — they are mechanical alternatives with identical electrical performance. D-connector provides a specific cable entry orientation suited to particular installation constraints. Choose based on the existing cable ecosystem in the facility and preferred mounting orientation — all three can coexist on the same PROFINET or I/O network. Consult the G115D operating instructions for dimensional drawings.
