A591

Drive HW initialization

ABB · ACS580 General Purpose Drive

What does A591 mean?

The drive's hardware is undergoing its initialization process. While typically a brief startup event, persistent initialization can signal a deeper issue with the drive's hardware or firmware. The auxiliary code might provide more context on the specific stage of initialization.

Complete Troubleshooting Guide

  1. 1

    Check the auxiliary code displayed (if any) to pinpoint the specific initialization sub-status.

  2. 2

    Allow sufficient time for the initialization to complete, as some complex setups may take longer.

  3. 3

    If the drive remains in initialization state, power cycle the unit (switch off and on).

  4. 4

    If the problem persists, gather auxiliary code information and contact your local ABB representative.
