The 6SL3230-3YE32-1AB0 is the B-suffix full-feature variant of the 22 kW C2-filtered G120X with DC link terminals. It combines a 61 A output stage, integrated Category C2 EMC filter, and built-in IOP-2 intelligent operator panel in the FSD frame format (200 × 472 × 239 mm, IP20).

IOP-2 operator panel: commissioning where the drive lives

The integrated IOP-2 provides a graphical interface for local drive setup, parameter adjustment, fault diagnostics, and parameter backup without external software. In water/wastewater facilities where drives are installed in distributed control cabinets, the IOP-2 enables on-site technicians to verify drive status, clear faults, and adjust setpoints directly — reducing reliance on remote access or laptop-based tools for routine tasks.

How the B-suffix completes the 1Ax group

The P-suffix (6SL3230-3YE32-1AP0) and F-suffix (6SL3230-3YE32-1AF0) share the same C2 filter and DC terminal hardware but omit the IOP-2 panel — commissioning on those variants is performed via the drive's fieldbus interface using Siemens Starter or TIA Portal. All three 1Ax variants share the FSD frame and suit pump, fan, and compressor drives in water/wastewater and HVAC. Choose the B-suffix when the maintenance workflow benefits from direct operator access at the drive, and P or F when all commissioning and diagnostics are handled remotely.
