What this drive is
The ABB ACS580-01-023A-4 is a general-purpose variable frequency drive in the ACS580 family, built as a wall-mount package for 3-phase 480 V AC supplies and rated 15 Hp in normal duty or 10 Hp in heavy duty. Output current tracks the duty class: 23 A on normal duty and 14 A on heavy duty — the duty selection, not the headline Hp number, is what determines whether a given motor fits on this frame. Frame R2 keeps the footprint at H 19.80" x W 5.1" x D 9.41", so panel cutout and wall bracing are set before the field wiring run is even pulled.
Reading the duty ratings
Normal duty to 15 Hp at 23 A covers quadratic-torque loads — fans, pumps, centrifugal blowers — where the motor does not need to hold rated torque down to standstill. Heavy duty to 10 Hp at 14 A is the constant-torque envelope: conveyors, mixers, extruders, anything that can stall against the load and demands full torque at low speed. Specifying by Hp alone is the usual mistake on this frame — the 23 A / 14 A pair is what the motor protection actually keys off, so the BOM line should name the duty class alongside the Hp figure.
Frame-mate within the ACS580-01 line
On the same 480 V 3-phase R2 wall-mount platform, the closest listed alternative in the ACS580-01 family is the ACS580-01-014A-4 — same voltage, same phase, same 10 Hp class on the headline figure, and a drop-in for the same enclosure footprint. The ACS580-01-027A-4 (20 Hp) and ACS580-01-012A-4 (5 Hp) sit one frame class above and below respectively — both share the ACS580-01 series but move to a different physical frame, so neither is a same-cutout swap.
Sourcing posture
The ACS580-01-023A-4 is specified as a standard ACS580 family member in the ABB general-purpose drive line, sourced to order against the BOM — quote the exact order code on the RFQ so the duty class and frame are unambiguous at intake.
