What the line is reading on this BOM
The ABB ACH580-01-096A-4 is the 096A-4 rating in the ACH580-01 wall-mount series, sitting under the ABB Drives family in the motor-drives class used for HVAC and constant-torque pump and fan loads. At 28.58 kg the unit is a two-handed lift and the cabinet or backplate must be sized for that mass with clearance around the heat sink for cooling airflow.
Fit, ratings, and what to pin down before commissioning
The 01 form factor is the wall-mount IP21 package in the ACH580 family, so panel builders get a footprint that drops onto a standard backplate without larger-frame cabinet-mount hardware. For a 096A-4 rating the load profile is the usual HVAC and pump/fan sweet spot — sensorless vector covers the constant-torque case, and the firmware is tuned for pump curves and fan affinity laws rather than high-overload positioning duty, which is the ACH580's reason for existing alongside the ACS580 general-purpose line. Match the motor cable length to the drive's reflected-wave limit before energising; long runs may need a dV/dt or sine filter at the output to keep winding insulation inside its dv/dt window.
Where this unit sits against a same-class alternative
The closest same-frame alternate is the ACS580-01-078A-4, listed at 28.58 kg in the same Drives category — a general-purpose sibling rather than the ACH580's HVAC-tuned firmware, usable on a tight BOM line only when pump/fan macros are not required.
