Fault tracing

Fault history
When fault is detected, it is stored in the fault logger with a time stamp. The fault
history stores information on the 16 latest faults of the drive. Three of the latest faults
are stored at the beginning of a power switch off.
Signals 8.01 ACTIVE FAULT and 8.02 LAST FAULT store the fault codes of the most
recent faults.
Alarms can be monitored via alarm words 8.05 ALARM WORD 1 … 8.08 ALARM
WORD 4. Alarm information is lost at power switch off or fault reset.
