The SINAMICS G120X 6SL3230-3YE26-1UF0 is an 11 kW frequency converter in the FSC frame, configured with DC terminals and an unfiltered output stage. The F-suffix designates the alternative ordering channel — electrically identical to the P-suffix variant. It delivers 35 A at 380–480 V 3 AC for pump, fan, and compressor applications.

What does the 1UF0 suffix configuration mean?

The suffix 1UF0 decodes as: DC terminals present (1), unfiltered output (U), and the F-suffix variant (F). The F-suffix is the alternative ordering channel — same hardware as the P-suffix, different procurement path. DC terminals allow direct du/dt filter connection for long motor cable runs. Without an integrated EMC filter, external measures are needed where conducted emissions compliance applies.

How does the F-suffix differ from the B-suffix at 11 kW?

The 1UF0 (F-suffix) omits the IOP-2 operator panel included on the 1UB0 (B-suffix). When commissioning is handled via fieldbus from a connected PLC, the F-suffix variant provides the same 11 kW drive hardware without the panel cost.
