Drive HW initialization

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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

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

2. 4

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