Cause : PANEL LOSS comes when the drive has lost communication with the connected control panel or drive is in local control mode.

The A2008 code indicates a "Panel Loss Alarm" on your ABB ACS550 drive. This means that the drive has lost communication with the connected control panel.

To correct check:

  1. Communication lines and connections.
  2. Parameter 3002 PANEL COMM ERR.
  3. Parameters in Group 10: START/STOP/DIR and Group 11: REFERENCE SELECT (if drive operation is REM).
