What shows up on the workbench
The ABB ACH580-PDR-023A-4 is an ACH580-series motor drive from the ABB ACH580-PDR line, rated for 480 VAC operation and intended for the motor-drive slot in a control lineup. The ACH580 family is the HVAC/water/wastewater-flavored branch of the ABB drives catalog, but the -PDR form factor is built around the same panel-mount envelope the ACH580 ships in across its motor-drive class — so a buyer pulling this code is filling a motor-drive BOM line, not a logic or sensor slot.
