The 6SL3230-3YE20-0UB0 pairs an Unfiltered 4 kW FSB power stage with an IOP-2 intelligent operator panel. The Unfiltered configuration defers EMC compliance to external measures — the right approach for IT networks, long motor cables needing output filters, or sites with cabinet-level filtering already in place. The IOP-2 provides a graphical commissioning wizard and real-time diagnostics at the drive front panel, eliminating the need for a laptop during parameter entry and fault finding.
