When a 2.2 kW axis has to join the PROFINET machine network with safety built in, the 6SL3520-2XD02-2AF0 is the variant to specify. The F suffix brings PROFINET and EtherNet/IP with PROFIsafe, so STO (SIL 2 / PL d) rides the same cable as the control data - no separate safety wiring to the cabinet, and the drive shows up as a PROFIsafe node in the SIMATIC project.

At 11.8 A, 3AC 380-480 V, it is the 2.2 kW FSB frame (425 x 180 x 134 mm), IP65/IP66, UL Type 4X, with integrated C2 filter and brake chopper - a machine-mounted 2.2 kW node that talks Ethernet natively.

PROFINET with PROFIsafe, or a simpler link?

If the 2.2 kW motor is close to the panel and only needs run/stop, the 2AB0 (Local I/O) drops the network and the cost. If an ASi master already serves the machine, the 2AA0 is the low-cabling fit. The 2AF0 earns its place when you want one cable to carry control, diagnostics, and safe torque off - which on a SIMATIC PROFINET line is often the whole point of going distributed.
