What the 9.8 A and 4 kW decide for the motor load
The Siemens 6SL3220-3YE20-0AF0 is the 4 kW SINAMICS G120X frame, rated 9.8 A on a 3-phase input feeding a 3-phase output — the headline figure a panel builder matches against the motor FLA, not the kW nameplate, so a 4-pole motor drawing 8 A continuous sits inside the continuous rating with derating margin for the high carrier frequencies.
380–480 V supply and the fieldbus interfaces it lands on
Operating voltage 380–480 V across all three phases matches the European 400 V and US 480 V three-phase supplies without a transformer tap; the drive carries PROFINET and EtherNet/IP on the same comms card, so a controls cabinet already on either Ethernet-based fieldbus drops this frame onto the existing PLC I/O map without an extra gateway.
Frequency envelope, PWM, and the IP20 cabinet it lives in
The output stage runs from 0 Hz up to 550 Hz with a 4 kHz default PWM clock, and the input accepts 47–63 Hz — a wide enough envelope to bridge generator sets and 50/60 Hz mains without a configuration trip; rated –20 °C to +45 °C ambient in an IP20 enclosure, so the drive goes behind a panel door, not into washdown, and the depth/width of 218 × 73 mm at 232 mm tall sets the DIN-cabinet cut-out and the gland-plate cable bend room behind the unit.
Wiring side: screw terminals and the onboard relay
Power and control land on screw terminals, with one onboard relay output rated 30 VDC @ 5 A — enough to drive a brake release coil or a fault beacon directly off the drive without an interposing relay, simplifying the panel BOM at the smaller 4 kW frame.
