u Alarm and Error Displays
n Faults
Table 6.9 gives an overview of possible fault codes. As conditions such as overvoltage can trip both a fault and an alarm,
it is important to distinguish between faults and alarms in order to find the right corrective action.
When the drive detects a fault, the ALM indicator LEDs lights and the fault code appears on the display. The drive fault
contact MA-MB-MC will be triggered. If the ALM LED blinks and the code appearing on the operator screen is flashes,
then an alarm has been detected. See Minor Faults and Alarms on page 274 for a list of alarm codes.
