Headline ratings and motor fit
The 6SL3220-3YE28-0UF0 is a SINAMICS G120X frequency converter sized at 15 kW with a 30 A rated output current, driving three-phase induction or permanent-magnet motors up to that envelope on a 380–480 V supply — the figure that decides the BOM line is the 30 A continuous, not the kW, because motor nameplate FLA is what trips the drive on overload. Three-phase input on 47–63 Hz and three-phase output to the motor cover the standard industrial mains ranges; output frequency runs 0–550 Hz, which matters when the driven load is a high-speed spindle or a pump on a V-belt where head and flow need trimming outside the 50/60 Hz window. Default switching frequency is 4 kHz — raising it quiets motor whine but trims continuous output current per the SINAMICS derating curve, so cabinet-build sizing starts at 4 kHz and only steps up once the thermal budget is checked.
Plant-network and I/O
On-board PROFINET and EtherNet/IP means the drive drops into a Siemens PLC rack conversation and a Rockwell/Logix PAC conversation without a gateway card — one Ethernet cable handles cyclic process data, parameterisation, and diagnostics on either protocol. A single relay output (30 VDC, 5 A) handles the brake-release or fault-annunciation contact; discrete I/O is intentionally minimal because the heavy lifting is over the fieldbus, not the terminal block.
Cabinet footprint and ambient envelope
The converter body is 218 mm deep × 140 mm wide × 295 mm tall, an IP20 cabinet-mount format with screw terminations — designed to sit inside a sealed enclosure, not on the machine frame, so the panel builder allocates DIN or backplate space, gland-plate entries for the motor cable shield, and accounts for the 45 °C upper ambient around it. Operating range spans -20 °C to +45 °C; below 0 °C the cabinet heater brings the interior up before the drive is enabled, and above 40 °C the panel ventilation or filter-fan schedule is what keeps the drive inside its derating envelope.
Lifecycle position
The part sits in the mature lifecycle stage — not a fresh release, still factory-supported as a current-line G120X frame, but the planning signal is to confirm firmware compatibility and a spare slot against the BOM freeze rather than treat it as a brand-new series with a long roadmap tail.
