The 6SL3230-3YE42-1UB0 delivers 75 kW (LO) / 55 kW (HO) in the FSF frame with the 1UB0 suffix: DC terminals present, unfiltered, full-feature I/O. The B-variant offers the richest onboard I/O and communication feature set among the unfiltered 75 kW G120X drives — the most digital and analog channels, the broadest fieldbus support — for complex pump stations, multi-zone HVAC systems, and process fans where the drive itself must coordinate multiple sensors and actuators without a dedicated PLC. DC-link terminals add the flexibility of du/dt filter connection for long motor cables or common DC-bus integration in multi-drive regenerative systems. The unfiltered power stage leverages existing upstream EMC infrastructure for conducted-emissions compliance.

FSF enclosure: 305 × 709 × 360 mm, 84 kg — IP20 / UL Open Type, control-cabinet mounted with forced ventilation. Common G120X equipment: STO SIL 2 (terminals + PROFIsafe), integrated brake chopper, ECO-mode energy optimization, Profinet / USS / Modbus RTU onboard, and IE2/IE3/IE4 motor support with V/f or sensorless vector control to 550 Hz. High-overload rating is 150% for 60 seconds for demanding-start applications.
