What the G120XA frame at this rating actually drives
The Siemens 6SL3220-3YD46-0UB0 is a SINAMICS G120XA variable-frequency drive in the 110 kW IEC frame, sized for 400 V three-phase supplies and rated 201 A in low-overload duty (LO) with a maximum output of 222 A. Rated current 205 A at 380 V and 201 A at 400 V confirms the LO envelope is held across the European 380–400 V mains without de-rating; the rated-power figure sits at 110.00 kW IEC at 400 V LO.
Supply envelope and motor-side output
Line voltage is 380–440 V with a +10 % / −20 % tolerance band, so the drive rides through weak or lightly regulated industrial feeds and still holds 400 V nominal. Line frequency spans 47–63 Hz — the 50/60 Hz autotune is built in, no parameter swap needed for export builds. On the motor side, V/f control reaches 0–550 Hz and sensorless vector control 0–240 Hz; the default pulse frequency is 2 kHz, which keeps switching losses low at this frame size — expect to derate continuous output if you raise the carrier to quiet the motor acoustically.
Efficiency, losses, and the panel-side thermal budget
Efficiency is listed at 0.98 with a power loss of 2.270 kW — at 110 kW shaft output the drive sheds roughly 2.3 kW into the cabinet, which dictates the enclosure ventilation or cooling plan for a 19-inch or floor-standing build. Power factor sits in a 0.75–0.93 band depending on load and mains impedance, with a displacement factor of 0.99 — the variation is the harmonic content, not the fundamental. At 73.1 dB sound pressure level at 1 m the cold plate and fan noise is in line with mid-frame drives — cabinet mounting with attention to clearances matters more than acoustic treatment at this rating.
