Danfoss Vlt Error Code 2563 -

If you need to confirm that the issue is external and not the drive itself:

For critical processes (e.g., chiller plant, conveyor line), keep a spare drive and replace immediately. Then send the faulty drive to an authorized Danfoss repair center like Driveservice or Radwell . They will refurbish it with new capacitors and flashed firmware for a fraction of the new cost.
