n Minor Faults and Alarms
Refer to Table 6.5 for an overview of possible alarm codes. Conditions such as overvoltages can trip faults and alarms. It is
important to distinguish between faults and alarms to determine the proper corrective actions.
When the drive detects an alarm, the ALM indicator LED blinks and the alarm code display flashes. Most alarms trigger a
digital output programmed for alarm output (H2-oo = 10). A fault (not an alarm) is present if the ALM LED lights without
blinking. Refer to Faults on page 292
