Serial-fieldbus panels on a 200-240 V supply still need a correctly sized drive, and the 6SL3230-3YC28-0UB0 delivers: a 15 kW G120X converter with USS, Modbus RTU and BACnet MS/TP onboard, no transformer required.

When does the no-DC-terminal variant make sense?

This unit drops the DC terminals, so it is the simpler choice where no du/dt filter is needed. If long motor cables or older insulation call for one, the -1UB0 adds the DC terminal connection. Both output 73 A in an FSD frame, IP20, at 110% / 60 s overload.
