GE AF-650 GP Operating Instructions Manual page 51

Warnings
All warnings within the frequency converter are represented by a single bit within a warning word. A warning word is always an action parameter. Bit status FALSE
[0] means no warning, while bit status TRUE [1] means warning. Each bit status has a corresponding text string message. In addition to the warning word message
the master will also be notified via a change in the status word.
Alarms
Following an alarm message the frequency converter will enter a fault condition. Only after the fault has been rectified and the master has acknowledged the
alarm message by a bit in the Control Word, can the drive resume operation. All alarms within the drive are represented by a single bit within an alarm word. An
alarm word is always an action parameter. Bit status FALSE [0] means no alarm, while bit status TRUE [1] means alarm. In CIP, Alarms are divided in to two
categories:
- Major Recoverable Faults
- Major Unrecoverable Faults
Please refer to the following sections for a classification of the specific faults.
