Table 6.3 Fault Displays (2)
■ Minor Faults and Alarms
Refer to Table 6.4 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-†† = 10). A fault (not an alarm) is present if the ALM LED lights without blinking.
Refer to
Faults on page 271 for information on fault codes.
