ABB ACS580-01-046A-4 22 kW wall-mounted variable speed drive

ABB ACS580-01-046A-4 wall-mounted variable speed drive: 22 kW, 45 A, 400 V, for three-phase machine speed and torque control.

System function and position

Rebuilt from individual evidence

Evidence-backed applications

Unknown: limits requiring verification

The ACS580-01-046A-4 is documented as a low-voltage AC general-purpose wall-mounted drive with 22 kW nominal power, 45 A nominal output current, and a 400 V rating.

Its documented system role is to control the speed and torque of a three-phase electric machine; ABB lists compressors, conveyors, mixers, pumps, centrifuges, and fans as ACS580-01 applications.

ABB's family documentation lists integrated Safe Torque Off, Modbus RTU, USB PC connection, EMC filtering, and option slots; confirm the installed configuration before relying on an option or interface.

Unknown: the installed electric machine, wiring, parameter set, fieldbus options, enclosure option, and site conditions for this specific unit.

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Controls the speed and torque of a three-phase electric machine in a general-purpose drive application.
System position: Sits between the three-phase AC supply and the electric machine that drives a process load.
Upstream / inputs: The upstream side is the documented three-phase 380-480 V supply and the drive control interface.
Downstream / outputs: Provides controlled machine operation for loads such as pumps, fans, conveyors, compressors, mixers, and centrifuges.
Limitations: Unknown: site-specific electric-machine compatibility, options, wiring, parameters, and installation conditions require verification.

Inferences

In a motor-driven machine, the drive sits between the three-phase AC supply and the motor that drives the process load.
Confidence: medium
Rationale: ABB documents this exact reference as a wall-mounted variable speed drive, says it controls three-phase motor speed and torque, and names motor-driven loads; the exact site wiring topology still requires verification.

Next action

The captured manufacturer evidence supports the exact identity, rating, and concrete drive function; verify the installation context before making a compatibility decision.

Verify the machine nameplate, wiring, installed options, enclosure, and parameter backup against ABB documentation before repair or replacement.
