9.1 Fault 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 code, the name and a short
description of the fault or alarm.
The notifications vary in consequence and required
action. Faults make the drive stop and require reset
of the drive. Alarms inform of unusual operating
conditions but the drive will continue running. Info
may require resetting but do not affect the functioning
of the drive.
For some faults you can program different responses
in the application. See parameter group Protections.
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
