u Alarm and Error Displays
n Faults
Table 6.4 gives an overview of possible fault 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 a fault, the ALM indicator LED lights, the fault code appears on the HOA keypad, and the fault contact
DO-10 triggers. An alarm is present if the ALM LED blinks and the fault code on the HOA keypad flashes. Refer to Minor
Faults and Alarms on page 175 for a list of alarm codes.
