The 6SL3230-3YE36-1UB0 is the 37 kW G120X in the FSD frame with the 1UB0 suffix — 3C3 coating, unfiltered EMC, and the IOP-2 intelligent operator panel. Rated 102 A at low overload (150% for 60 seconds), it is the operator-accessible harsh-environment variant: the drive sits in a process cabinet with external EMC filtering, the 3C3 coating handles corrosive exposure, and the permanently mounted IOP-2 gives maintenance technicians local graphical access for commissioning and diagnostics without a PG/PC.

The IOP-2 provides a plain-text graphical display, guided commissioning wizards, and diagnostic readouts directly on the drive — valuable in wastewater or chemical plant installations where sending a technician back to the control room for every parameter check wastes time. The unfiltered configuration delegates EMC compliance to an external line filter or shielded cable strategy. FSD frame footprint: 200 × 472 × 239 mm, approximately 22 kg.
