Faults
Table 6.5 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
