This alarm indicates that the drive’s internal pre-charge circuit has failed to function correctly. In simple terms, when a drive powers up, it must slowly charge its internal DC bus capacitors to prevent a massive inrush of current. The A910 alarm triggers when the drive detects that the DC bus voltage has not risen as expected within a set time frame.
