Fault tracing

AULT TRACING
When an unusual operating condition is detected by the AC drive control diagnostics, the drive
initiates a notification visible, for example, on the keypad. The keypad will show the ordinal
number of the fault, the fault code and a short fault description.
The fault can be reset with the Reset button on the control keypad or via the I/O terminal. The
faults are stored in the Fault history menu which can be browsed. The different fault codes you
will find in the table below. This fault table presents only the faults related to the fieldbus in
use.
NOTE: When contacting distributor or factory because of a fault condition, always write down
all texts and codes on the keypad display and send a description of the problem together with
