How to reset

The drive can be reset either by pressing the RESET key on the control panel or PC
tool, or by switching the supply voltage off for a while. When the fault is removed, the
motor can be restarted.
Faults can also be reset from an external source selected with parameter 46.80
FAULT RESET. In addition, the drive features an automatic fault reset function. For
more information, see section Drive faults on page 133.

Fault history

When a 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.
Parameters 08.01
the most recent faults.
Alarms can be monitored via alarm words
WORD 4. Alarm information is lost at power switch off or fault reset.
