The SINAMICS G115D 6SL3520-2XA22-2AA0 is a 2.2 kW wall-mounted distributed drive in the FSB fanless frame with basic I/O (AA0 suffix). It is designed for horizontal conveyor sections in intralogistics, packaging, and assembly applications where the drive mounts directly on the machine frame near the motor. Natural convection cooling eliminates fan noise and maintenance while the IP65/IP66 enclosure withstands washdown and dust environments.

How does the AA0 differ from the AF0 at 2.2 kW?

Both variants share the same 2.2 kW power rating, FSB fanless frame (425 × 180 × 134 mm), IP65/IP66 protection, integrated C2 EMC filter, and braking chopper. The AA0 provides basic digital and analog I/O for hardwired start/stop and speed reference control — suitable for simple conveyor zones where the drive operates as a standalone unit with discrete signals from a local controller. The AF0 upgrades to PROFINET with PROFIsafe for networked operation with integrated safety over a single Ethernet cable.
