Sizing the ACS580-01-046A-4 to the motor
The ABB ACS580-01-046A-4 is a lower-voltage AC drive in the ACS580 series, and the three numbers a buyer actually has to reconcile against the motor nameplate are heavy-duty 18.5, light-duty 22, and the nominal 22 — the same nominal figure appears against both light-duty and the nominal-rating line, which means ABB publishes 22 kW as the default operating point and 18.5 kW as the heavy-duty / constant-torque ceiling you have to respect when the load is a pump, compressor, or conveyor that does not back off. Max output current is 67.9 A. That figure is what sizes the output cabling and the line-side breaker against the motor's locked-rotor inrush. Footprint is 22.9 cm x 20.3 cm x 49 cm — that is a single-cabinet column, bookcase-mount in the usual ACS580-01 frame, and it leaves room above and below for the line reactor and the brake chopper wiring if the application is a vertical load or a fast-stop profile.
Same-frame sibling worth weighing against the BOM
Step one notch down the ACS580-01 family and you land on the ACS580-01-039A-4 — identical 22.9 cm x 20.3 cm x 49 cm frame, identical 11.8 Kg mass, but the current ceiling drops from 67.9 A to 56.9 A and the kW step falls to 15 heavy-duty / 18.5 light-duty / 18.5 nominal. That is a meaningful split for the panel builder or the MRO planner: the cabinet cut-out, gland plate pattern, and backplane footprint carry over unchanged between the two, but the contactor, output cable, and the brake-resistor thermal rating on the smaller unit are sized for the lower current — so if the panel was specified around the 039A and you are upgrading to the 046A for motor headroom, the wiring and the line-side protection have to be re-rated, not just the drive.
Sourcing reality for this order code
Shipping weight on the order is 13 Kg against the unit's 11.8 Kg, which is the packaging delta a receiving dock plans for, not a spec that drives selection — flag it once so the inbound scale check does not get flagged as a discrepancy.
