The 6SL3230-3YE40-1UP0 delivers 55 kW in the FSE frame — a mid-size G120X frame one step below the largest FSF. With the 1UP0 suffix it offers DC terminals for du/dt filter or common DC-bus connection, no integrated EMC filter (unfiltered), and basic onboard I/O (P-variant). The DC-link access is the defining feature: it enables integration into multi-drive common-DC-bus systems where regenerative energy from one axis can be shared, or connection of an external du/dt filter when long motor-cable runs demand voltage-reflection mitigation. At 55 kW rated with 149 A output and 110% overload for 60 seconds, this drive suits mid-size centrifugal pumps, cooling-tower fans, and industrial ventilation where the power requirement sits between the compact FSD and the heavy-duty FSF frames.

FSE enclosure: 275 × 551 × 239 mm — IP20 / UL Open Type, control-cabinet mounted with forced ventilation. More compact than the FSF (305×709×360 mm, 84 kg), the FSE fits space-constrained control cabinets while delivering the same 55 kW class output. All G120X variants include STO SIL 2 (terminals and PROFIsafe), integrated brake chopper, ECO-mode energy optimisation, Profinet / USS / Modbus RTU onboard, and support for IE2/IE3/IE4 motors with V/f or sensorless vector control to 550 Hz.
