The 6SL3230-3YE40-1UF0 delivers 55 kW in the FSE frame with the 1UF0 suffix: DC terminals present, unfiltered, enhanced I/O. The F-variant adds more onboard digital and analog I/O channels over the basic 1UP0, supporting multi-signal pump and fan applications — flow, pressure, temperature, vibration monitoring — without external I/O expansion modules. DC-link terminal access enables either du/dt filter connection for long motor-cable runs or integration into common-DC-bus multi-drive systems. The unfiltered power stage relies on the installation's existing upstream EMC infrastructure or a C3 industrial grid for conducted-emissions compliance, keeping the drive-side BOM cost down.

The FSE enclosure measures 275 × 551 × 239 mm — IP20 / UL Open Type, control-cabinet mounted with forced ventilation. One frame below the FSF (305×709×360 mm), the FSE offers a more compact footprint for space-constrained cabinets at the 55 kW power level. Platform-standard G120X features include STO SIL 2 (terminals and PROFIsafe), integrated brake chopper, ECO-mode energy savings, onboard Profinet / USS / Modbus RTU, and IE2/IE3/IE4 motor support with V/f or sensorless vector control to 550 Hz. Light-overload rating: 110% for 60 seconds.
