The 6SL3520-1XH67-5AA0 is the hardwired I/O baseline at the top of the G115D power range: 7.5 kW, 38 A continuous, FSC frame with integrated fan cooling, 4DI + 1AI control interface. For the system integrator whose control architecture uses a central PLC with analog and discrete I/O distributed to each machine section, the AA0 variant provides the simplest electrical interface to the largest G115D drive.

7.5 kW with hardwired control — when it makes sense

A 7.5 kW drive on a main conveyor segment in a brownfield facility may already have a dedicated PLC with spare analog outputs and digital I/O wired to the machine junction box. Adding PROFINET would require a network drop, a managed switch port, and IP address management — changes to the automation infrastructure that a hardwired drive does not demand. The AA0 variant accepts a 0-10 V speed reference and discrete run/reverse/fault-reset signals on the existing terminal strip, making it a drop-in replacement for an older drive without touching the network architecture. The PROFINET and EtherNet/IP ports remain on board for future migration, but commissioning on day one follows the same wiring practices the maintenance team already knows.
