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 digital operator, and the fault
contact MA-MB-MC triggers. An alarm is present if the ALM LED blinks and the fault code on the digital operator flashes.
Refer to Minor Faults and Alarms on page 293 for a list of alarm codes.
