22 kW pump and fan drive — what the ratings tell you
The 6SL3220-3YD32-0UB0: That LO rating means it's sized for variable-torque loads like centrifugal pumps and fans where the current demand stays below the nameplate most of the run time. The input accepts 380 to 440 V three-phase AC, +10 % / -20 %, which covers nominal 400 V grids across Europe and Asia with room for sag. Line frequency tolerance is 47 to 63 Hz, so it handles 50 Hz and 60 Hz supplies without reconfiguration. Output frequency reaches 550 Hz in V/f control mode — enough for high-speed spindle or centrifuge applications — while vector control tops out at 240 Hz, which covers most standard induction and permanent-magnet motor ranges.
Efficiency and thermal budget for panel planning
The power factor range of 0.75 to 0.93 tells you the drive's input stage draws reactive current at light load; if you're sizing upstream transformers or generators, budget for the lower end of that band. Sound pressure level is 62.2 dB at 1 m — about the noise of a quiet office printer. The 4 kHz pulse frequency is the default; raising it quiets the motor whine but increases switching losses, so factor that into the thermal calculation if you go above 4 kHz.
