The 6SL3230-3YE32-1UB0 is the B-suffix full-feature variant of the 22 kW SINAMICS G120X in the unfiltered configuration with DC link terminals. It combines a 61 A output stage at 380–480 V 3 AC with a built-in IOP-2 intelligent operator panel, housed in an FSD frame (200 × 472 × 239 mm) for IP20 cabinet mounting.

IOP-2 panel: local commissioning without a laptop

The IOP-2 (Intelligent Operator Panel 2) provides a graphical display and keypad for drive parameterization, status monitoring, fault diagnostics, and parameter backup directly at the drive. For water/wastewater facilities where control cabinets are distributed across a plant, the IOP-2 allows on-site technicians to commission and troubleshoot without carrying a PC. The panel supports plain-text parameter descriptions and a guided startup wizard, reducing commissioning time versus software-only setup.

How the B-suffix compares to P and F alternatives

The P-suffix (6SL3230-3YE32-1UP0) and F-suffix (6SL3230-3YE32-1UF0) share the same unfiltered power stage and DC terminal provision but omit the IOP-2 panel — commissioning is handled remotely via the drive's fieldbus interface. Choose the B-suffix when local operator access is part of your maintenance workflow. All three variants share the FSD frame dimensions, and the unfiltered configuration requires an external EMC filter when Category C2 compliance per IEC 61800-3 is needed.
