Alarm and fault indications
Fault is indicated with a red LED. See section LEDs on page 356.
An alarm or fault message on the panel display indicates abnormal drive status.
Using the information given in this chapter, most alarm and fault causes can be identified and corrected. If not, contact an ABB representative.
The four digit code number in parenthesis after the fault is for the fieldbus communication. See chapters Fieldbus control with embedded fieldbus on page 301 and Fieldbus control with fieldbus adapter on page 325.

How to reset
The drive can be reset either by pressing the keypad key (basic control panel) or (assistant control panel), through digital input or fieldbus, or by switching the supply voltage off for a while. The source for the fault reset signal is selected by EXIT/RESET
336 Fault tracing parameter 1604 FAULT RESET SEL. When the fault has been removed, the motor can be restarted.

Fault history
When a fault is detected, it is stored in the fault history. The latest faults are stored together with the time stamp.
Parameters 0401 LAST FAULT, 0412 PREVIOUS FAULT 1 and 0413 PREVIOUS FAULT 2 store the most recent faults. Parameters 0404...0409 show drive operation data at the time the latest fault occurred. The assistant control panel provides
additional information about the fault history. See section Fault logger mode on page 101 for more information.
