The 6SL3230-3YE16-1UB0 pairs 2.2 kW FSA unfiltered hardware with DC terminals and the IOP-2 intelligent operator panel. The IOP-2 provides a graphical, full-text commissioning interface directly on the drive — parameter setting, diagnostics, and fault acknowledgement in plain language, without a laptop or engineering software. This suits installations where the service technician accesses the drive through the cabinet door without TIA Portal — remote pump stations, HVAC plant rooms, or building services.
