The SINAMICS G120X 6SL3230-3YE28-1AF0 is a 15 kW frequency converter in the FSC frame size, combining an integrated Category C2 EMC filter and DC terminals for du/dt filter connection. It is designed for pump, fan, and compressor applications in water/wastewater, building technology, and HVAC sectors requiring reliable variable-speed control at 380–480 V 3 AC.

What does the 1AF0 suffix configuration mean?

The suffix 1AF0 decodes as: DC terminals present (1), integrated Category C2 EMC filter (A), and the F-suffix variant (F). The F-suffix designates the alternative ordering channel — electrically identical to the P-suffix variant but distinguished for procurement and logistics purposes. The integrated C2 filter ensures conducted emissions compliance without external EMC measures, and the DC terminals allow direct connection of a du/dt filter for motor winding protection on long cable runs.

How does the F-suffix differ from the B-suffix variant?

At the same 15 kW power rating with C2 EMC filter and DC terminals, the 1AF0 (F-suffix) omits the IOP-2 operator panel included on the 1AB0 (B-suffix). If commissioning is handled entirely via a connected controller over fieldbus, the F-suffix variant provides the same C2-filtered drive hardware with DC terminals without the panel cost. For applications requiring a local graphical interface, the B-suffix with IOP-2 is the appropriate choice.
