The ABB ACS580-01-04A1-4 sits in the ACS580-01 family of general-purpose drives and is the -04 rating step with an A1 terminal style and a -4 enclosure suffix, as carried on the listing description. The brand of record is ABB (ASEA BROWN BOVERI), and the order code is the contract — ACS580-01-04A1-4 is what gets stamped on the PO and what the panel nameplate should be cross-checked against at goods-in.
What the suffix actually means at the panel
In the ACS580-01 order code convention, the -04A1-4 tail is a stack of three distinct choices — the rating frame (-04), the terminal/bypass style (A1), and the enclosure/IP class (-4) — so any substitute on the BOM has to repeat all three, not just the nominal kW step. A buyer cross-shopping a replacement inside the same family should treat a different A1 vs B1 terminal block, or a different enclosure IP rating, as a hard mismatch on the wiring side, even if the horsepower stamp is adjacent.
Commissioning posture
For an ACS580-01 install the usual first-power checks still apply: confirm the input feed matches the -4 enclosure class rating, bond the drive chassis to the panel ground bar with a short pigtail, and keep motor cable length inside the manufacturer's reflected-wave envelope — long runs to the motor need a dV/dt or sine filter rather than a longer cable. Parameter set should be loaded against the actual motor nameplate (voltage, FLA, cos φ, service factor) before the first ramp; sensorless-vector control on the ACS580 platform is only as good as the motor data it is fed.
