The SINAMICS G120X 6SL3230-3YE26-1AB0 is an 11 kW frequency converter in the FSC frame, combining an integrated Category C2 EMC filter, DC terminals for du/dt filter connection, and an IOP-2 operator panel. This is the most feature-rich configuration at the 11 kW power level. It delivers 35 A at 380–480 V 3 AC for pump, fan, and compressor applications.

What does the 1AB0 suffix configuration include?

The suffix 1AB0 decodes as: DC terminals present (1), integrated Category C2 EMC filter (A), and full-feature configuration with IOP-2 graphical operator panel (B). The C2 filter provides built-in conducted emissions compliance. DC terminals enable direct du/dt filter connection for motor winding protection on long cable runs. The IOP-2 panel enables local commissioning, parameterization, and diagnostics at the drive.

How does the 1AB0 compare to the 0AB0 variant?

Both share the C2 EMC filter and IOP-2 panel at 11 kW in the FSC frame. The difference is the first suffix digit: 1AB0 includes DC terminals for du/dt filter connection, while 0AB0 does not. For applications with long motor cable runs where voltage reflections could stress motor insulation, the 1AB0's DC terminals provide the necessary connection point.
