Faults
When the drive detects a fault, the ALM indicator LEDs remain lit without flashing. If the
LEDs flash, the drive has detected a minor fault or alarm. Refer to Minor Faults and
Alarms on page 124 for more information. Conditions such as overvoltage or external faults
can trip both faults and minor faults, therefore it is important to note whether the LEDs remain
lit or if the LEDs flash.

Minor Faults and Alarms
When a minor fault or alarm occurs, the ALM LED flashes and the text display shows an
alarm code. A fault has occurred if the text remains lit and does not flash. Refer to Alarm
Detection on page 134. An overvoltage situation, for example, can trigger both faults and
minor faults. It is therefore important to note whether the LEDs remain lit or if the LEDs flash.
