Alarm and fault indications
An alarm or a fault message indicates abnormal drive status. Most alarm and fault
causes can be identified and corrected using this information. If not, an ABB
representative should be contacted.
The four-digit code number in brackets after the message is for the fieldbus
communication.
The alarm/fault code is displayed on the 7-segment display of the drive. The
following table describes the indications given by the 7-segment display.
How to reset
The drive can be reset either by pressing the reset key on the PC tool ( ) or control
panel (RESET) or switching the supply voltage off for a while. When the fault has
been removed, the motor can be restarted.
A fault can also be reset from an external source by parameter 10.08 FAULT RESET
