The SINAMICS G120X 6SL3230-3YE28-1UF0 is a 15 kW frequency converter in the FSC frame size, configured with DC terminals and an unfiltered output stage. 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 1UF0 suffix configuration mean?

The suffix 1UF0 decodes as: DC terminals present (1), unfiltered output with no integrated EMC filter (U), and the F-suffix variant (F). The F-suffix designates the alternative ordering channel — electrically identical to the P-suffix (standard catalog) variant but distinguished for procurement and logistics purposes. DC terminals allow direct connection of a du/dt filter to protect motor windings on long cable runs. Without an integrated EMC filter, external EMC measures must be applied where conducted emissions compliance is required.

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

At the same 15 kW power rating with DC terminals and unfiltered output, the 1UF0 (F-suffix) omits the IOP-2 operator panel included on the 1UB0 (B-suffix). If local graphical commissioning and diagnostics are not required — for example, when commissioning is handled entirely via a connected controller over fieldbus — the F-suffix variant provides the same drive hardware without the panel. For applications needing a local operator interface, the B-suffix with IOP-2 is the appropriate choice.
