The SINAMICS G120X 6SL3230-3YE30-1AB0 is an 18.5 kW frequency converter in the FSD frame size, combining an integrated Category C2 EMC filter, DC terminals for du/dt filter connection, and an IOP-2 operator panel. 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 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). This is the most feature-rich configuration at the 18.5 kW power level: the C2 filter provides built-in conducted emissions compliance for industrial environments, the DC terminals enable direct connection of a du/dt filter for motor winding protection on long cable runs, and the IOP-2 panel provides a local graphical interface for commissioning, parameterization, and diagnostics.

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

Both the 1AB0 and 0AB0 share the C2 EMC filter and IOP-2 operator panel at 18.5 kW in the FSD frame. The key difference is the first suffix digit: 1AB0 includes DC terminals, while 0AB0 does not. If the application involves long motor cable runs where voltage reflections could stress the motor insulation, the 1AB0's DC terminals allow a du/dt filter to be connected directly at the drive output — a capability the 0AB0 lacks. For standard cable lengths where a du/dt filter is not required, the 0AB0 provides the same core drive performance.
